196-487: A mosaic is a pattern or image made of small regular or irregular pieces of colored stone, glass or ceramic, held in place by plaster / mortar , and covering a surface. Mosaics are often used as floor and wall decoration, and were particularly popular in the Ancient Roman world. Mosaic today includes not just murals and pavements, but also artwork, hobby crafts, and industrial and construction forms. Mosaics have

392-545: A Carthaginian army there. This was the first time a European force had invaded the region. After this war he controlled most of south-east Sicily and had himself proclaimed king, in imitation of the Hellenistic monarchs of the east. Agathocles then invaded Italy ( c.  300 BC ) in defense of Tarentum against the Bruttians and Romans , but was unsuccessful. Greeks in pre-Roman Gaul were mostly limited to

588-406: A Hellenistic period is a 19th-century concept, and did not exist in ancient Greece . Although words related in form or meaning, e.g. Hellenist ( Ancient Greek : Ἑλληνιστής , Hellēnistēs ), have been attested since ancient times, it has been attributed to the 19th century German historian Johann Gustav Droysen , who in his classic work Geschichte des Hellenismus ( History of Hellenism ), coined

784-478: A binder. In Martin E. Weaver 's seminal work he says, "Mud plaster consists of clay or earth which is mixed with water to give a 'plastic' or workable consistency. If the clay mixture is too plastic it will shrink, crack and distort on drying. Sand, fine gravels and fibres were added to reduce the concentrations of fine clay particles which were the cause of the excessive shrinkage." Manure was often added for its fibre content. In some building techniques straw or grass

980-495: A bowl. Both of these themes were widely copied. Greek figural mosaics could have been copied or adapted paintings, a far more prestigious artform, and the style was enthusiastically adopted by the Romans so that large floor mosaics enriched the floors of Hellenistic villas and Roman dwellings from Britain to Dura-Europos . Most recorded names of Roman mosaic workers are Greek, suggesting they dominated high quality work across

1176-580: A bucket of plaster as part of a school art project. Plaster that contains powdered silica or asbestos presents health hazards if inhaled repeatedly. Asbestos is a known irritant when inhaled and can cause cancer, especially in people who smoke, and inhalation can also cause asbestosis . Inhaled silica can cause silicosis and (in very rare cases) can encourage the development of cancer . Persons working regularly with plaster containing these additives should take precautions to avoid inhaling powdered plaster, cured or uncured. Hellenistic After

1372-662: A carefully neutral posture and acting to preserve the balance of power between the major Hellenistic kingdoms. Initially, Rhodes had very close ties with the Ptolemaic kingdom. Rhodes later became a Roman ally against the Seleucids, receiving some territory in Caria for their role in the Roman–Seleucid War (192–188 BC). Rome eventually turned on Rhodes and annexed the island as a Roman province. The west Balkan coast

1568-578: A combined Theban and Athenian army at the Battle of Chaeronea after a decade of desultory conflict. In the aftermath, Philip formed the League of Corinth , effectively bringing the majority of Greece under his direct sway. He was elected Hegemon of the league, and a campaign against the Achaemenid Empire of Persia was planned. However in 336 BC, while this campaign was in its early stages, he

1764-477: A common Attic -based Greek dialect, known as Koine Greek , which became the lingua franca throughout the ancient world. During the Hellenistic period, Greek cultural influence reached its peak in the Mediterranean and beyond. Prosperity and progress in the arts , literature , theatre , architecture , music , mathematics , philosophy , and science characterize the era. The Hellenistic period saw

1960-466: A common practice at that time not just in the construction of Economy village when the settlement was founded in 1824. Specifications for the construction of, "Lock keepers houses on the Chesapeake and Ohio Canal, written about 1828, require stone walls to be laid with clay mortar, excepting 3 inches on the outside of the walls … which (are) to be good lime mortar and well pointed." The choice of clay

2156-480: A crab, a lobster, shrimps, mushrooms, flowers, a stag and two cruciform designs surround the smaller of the two inscriptions, which reads: In fulfilment of the vow (prayer) of those whose names God knows. This anonymous dedicatory inscription is a public demonstration of the benefactors' humility and an acknowledgement of God's omniscience. The abundant variety of natural life depicted in the Butrint mosaics celebrates

2352-467: A cult arose where human skulls were decorated with plaster and painted to appear lifelike. The Romans brought plaster-work techniques to Europe . Clay plaster is a mixture of clay , sand and water often with the addition of plant fibers for tensile strength over wood lath . Clay plaster has been used around the world at least since antiquity. Settlers in the American colonies used clay plaster on

2548-562: A deer, four young men wrestling a wild bull to the ground, and a gladiator resting in a state of fatigue, staring at his slain opponent. The mosaics decorated the walls of a cold plunge pool in a bath house within a Roman villa. The gladiator mosaic is noted by scholars as one of the finest examples of mosaic art ever seen – a "masterpiece comparable in quality with the Alexander Mosaic in Pompeii ." A specific genre of Roman mosaic

2744-425: A detergent agent (such as sodium dodecylbenzene sulfonate ). Plaster may also be used to create complex detailing for use in room interiors. These may be geometric (simulating wood or stone) or naturalistic (simulating leaves, vines, and flowers). These are also often used to simulate wood or stone detailing found in more substantial buildings. In modern days this material is also used for false ceiling . In this,

2940-403: A fire. Early versions of protective plasters often contain asbestos fibres, which since have been outlawed in many industrialized nations. Recent plasters for fire protection either contain cement or gypsum as binding agents as well as mineral wool or glass fiber to add mechanical strength. Vermiculite , polystyrene beads or chemical expansion agents are often added to decrease the density of

3136-604: A fleet. Ptolemy invaded Syria and defeated Antigonus' son, Demetrius Poliorcetes , in the Battle of Gaza of 312 BC which allowed Seleucus to secure control of Babylonia , and the eastern satrapies. In 310 BC, Cassander had young King Alexander IV and his mother Roxana murdered, ending the Argead dynasty which had ruled Macedon for several centuries. Antigonus then sent his son Demetrius to regain control of Greece. In 307 BC he took Athens, expelling Demetrius of Phaleron , Cassander's governor, and proclaiming

3332-416: A golden background date back to the 5th and to the 8th century, although it was restored many times later. The baptistery of the basilica, which was demolished in the 15th century, had a vault covered with gold-leaf tesserae, large quantities of which were found when the site was excavated. In the small shrine of San Vittore in ciel d'oro, now a chapel of Sant'Ambrogio, every surface is covered with mosaics from

3528-455: A hand-made and pleasing textured alternative to machine-made modern substrate finishes. But clay plaster finishes are rare and fleeting. According to Martin Weaver, "Many of North America's historic building interiors … are all too often … one of the first things to disappear in the frenzy of demolition of interiors which has unfortunately come to be a common companion to 'heritage preservation' in

3724-504: A league against Cassander's Macedon. The decisive engagement of the war came when Lysimachus invaded and overran much of western Anatolia, but was soon isolated by Antigonus and Demetrius near Ipsus in Phrygia . Seleucus arrived in time to save Lysimachus and utterly crushed Antigonus at the Battle of Ipsus in 301 BC. Seleucus' war elephants proved decisive; Antigonus was killed, and Demetrius fled back to Greece to attempt to preserve

3920-506: A liberator than a conqueror. In addition, much of the area conquered would continue to be ruled by the Diadochi , Alexander's generals and successors. Initially, the whole empire was divided among them; however, some territories were lost relatively quickly or only remained nominally under Macedonian rule. After 200 years, only much reduced and rather degenerate states remained, until the conquest of Ptolemaic Egypt by Rome. When Alexander

4116-467: A lime and sand mortar to provide a weather proof seal to protect from water penetration. This allowed a rendering of clay plaster and setting coat of thin lime and fine sand on exterior-walled rooms. Split lath was nailed with square cut lath nails, one into each framing member. With hand split lath the plasterer had the luxury of making lath to fit the cavity being plastered. Lengths of lath two to six foot are not uncommon at Economy Village. Hand split lath

4312-660: A log of straight grained wood of the required length. The log is split into quarters and then smaller and smaller bolts with wedges and a sledge. When small enough, a froe and mallet were used to split away narrow strips of lath. Farm animals provided hair and manure for the float coat of plaster. Fields of wheat and grains provided straw and hay to reinforce the clay plaster. But there was no uniformity in clay plaster recipes. Manure provides fiber for tensile strength as well as protein adhesive. Unlike casein used with lime plaster, hydrogen bonds of manure proteins are weakened by moisture. With braced timber-framed structures clay plaster

4508-706: A long history, starting in Mesopotamia in the 3rd millennium BC. Pebble mosaics were made in Tiryns in Mycenean Greece; mosaics with patterns and pictures became widespread in classical times, both in Ancient Greece and Ancient Rome . Early Christian basilicas from the 4th century onwards were decorated with wall and ceiling mosaics. Mosaic art flourished in the Byzantine Empire from

4704-609: A major form of artistic expression. The Roman church of Santa Costanza , which served as a mausoleum for one or more of the Imperial family, has both religious mosaic and decorative secular ceiling mosaics on a round vault, which probably represent the style of contemporary palace decoration. The mosaics of the Villa Romana del Casale near Piazza Armerina in Sicily are the largest collection of late Roman mosaics in situ in

4900-622: A mixture of suitable plaster, sand, Portland cement and water which is normally applied to masonry interiors and exteriors to achieve a smooth surface. Interior surfaces sometimes receive a final layer of gypsum plaster. Walls constructed with stock bricks are normally plastered while face brick walls are not plastered. Various cement-based plasters are also used as proprietary spray fireproofing products. These usually use vermiculite as lightweight aggregate. Heavy versions of such plasters are also in use for exterior fireproofing, to protect LPG vessels, pipe bridges and vessel skirts. Cement plaster

5096-533: A more intimate and delicate style, of which The Angel before St Joachim — with its pastoral backdrop, harmonious gestures and pensive lyricism – is considered a superb example. The 9th- and 10th-century mosaics of the Hagia Sophia in Constantinople are truly classical Byzantine artworks. The north and south tympana beneath the dome was decorated with figures of prophets, saints and patriarchs. Above

5292-626: A new agreement with Antipater at the Treaty of Triparadisus . Antipater was made regent of the Empire, and the two kings were moved to Macedon. Antigonus remained in charge of Asia Minor, Ptolemy retained Egypt, Lysimachus retained Thrace and Seleucus I controlled Babylon . The second Diadochi war began following the death of Antipater in 319 BC. Passing over his own son, Cassander , Antipater had declared Polyperchon his successor as Regent . Cassander rose in revolt against Polyperchon (who

5488-471: A patient's head and neck, and liquid plaster is used to fill the impression and produce a plaster bust. The transparent material polymethyl methacrylate (Plexiglas, Perspex) is then vacuum formed over this bust to create a clear face mask which will hold the patient's head steady while radiation is being delivered. In dentistry, plaster is used for mounting casts or models of oral tissues. These diagnostic and working models are usually made from dental stone,

5684-454: A plaster positive was desired this would be constructed or cast to form a durable image artwork. As a model for stonecutters this would be sufficient. If intended for producing a bronze casting the plaster positive could be further worked to produce smooth surfaces. An advantage of this plaster image is that it is relatively cheap; should a patron approve of the durable image and be willing to bear further expense, subsequent molds could be made for

5880-410: A plaster secondary support. Some, like Michelangelo's Sistine Chapel ceiling , are executed in fresco , meaning they are painted on a thin layer of wet plaster, called intonaco ; the pigments sink into this layer so that the plaster itself becomes the medium holding them, which accounts for the excellent durability of fresco. Additional work may be added a secco on top of the dry plaster, though this

6076-407: A positive model of the limb and used in fabricating the final medical device. In addition, dentures (false teeth) are made by first taking a dental impression using a soft, pliable material that can be removed from around the teeth and gums without loss of fidelity and using the impression to creating a wax model of the teeth and gums. The model is used to create a plaster mold (which is heated so

6272-400: A primary advantage of the material is that it is resistant to a fire within a room and so can assist in reducing or eliminating structural damage or destruction provided the fire is promptly extinguished. Lime plaster is used for frescoes , where pigments , diluted in water, are applied to the still wet plaster. USA and Iran are the main plaster producers in the world. Cement plaster is

6468-420: A remarkable property of setting into a hard mass on wetting with water. CaSO 4 ⋅ 1 2 H 2 O + 1 1 2 H 2 O ⟶ CaSO 4 ⋅ 2 H 2 O {\displaystyle {\ce {CaSO4.1/2H2O + 1 1/2H2O -> CaSO4.2H2O}}} Plaster of Paris

6664-431: A rigid denture base. Moreover, in dentistry there are 5 types of gypsum products depending on their consistency and uses: 1) impression plaster (type 1), 2) model plaster (type 2), dental stones (types 3, 4 and 5) In orthotics and prosthetics, plaster bandages traditionally were used to create impressions of the patient's limb (or residuum). This negative impression was then, itself, filled with plaster of Paris, to create

6860-529: A similar iconography. 6th-century pieces are rare in Rome but the mosaics inside the triumphal arch of the basilica of San Lorenzo fuori le mura belong to this era. The Chapel of Ss. Primo e Feliciano in Santo Stefano Rotondo has very interesting and rare mosaics from the 7th century. This chapel was built by Pope Theodore I as a family burial place. In the 7th–9th centuries Rome fell under

7056-435: A standing army of mercenaries and a small core of Greco-Macedonian settlers. Promotion of immigration from Greece was important in the establishment of this system. Hellenistic monarchs ran their kingdoms as royal estates and most of the heavy tax revenues went into the military and paramilitary forces which preserved their rule from any kind of revolution. Macedonian and Hellenistic monarchs were expected to lead their armies on

7252-416: A stronger, harder and denser derivative of plaster which is manufactured from gypsum under pressure. Plaster is also used to invest and flask wax dentures, the wax being subsequently removed by "burning out," and replaced with flowable denture base material. The typically acrylic denture base then cures in the plaster investment mold. Plaster investments can withstand the high heat and pressure needed to ensure

7448-535: A summary of Arrian 's Events after Alexander , by Photios I of Constantinople . Lesser supplementary sources include Curtius Rufus , Pausanias , Pliny , and the Byzantine encyclopedia the Suda . In the field of philosophy, Diogenes Laërtius ' Lives and Opinions of Eminent Philosophers is the main source; works such as Cicero 's De Natura Deorum also provide some further detail of philosophical schools in

7644-579: Is Athens , which had been decisively defeated by Antipater in the Lamian war (323–322 BC) and had its port in the Piraeus garrisoned by Macedonian troops who supported a conservative oligarchy . After Demetrius Poliorcetes captured Athens in 307 BC and restored the democracy , the Athenians honored him and his father Antigonus by placing gold statues of them on the agora and granting them

7840-546: Is a panel in Hagia Sophia depicting Emperor John II and Empress Eirene with the Theotokos (1122–34). The empress with her long braided hair and rosy cheeks is especially capturing. It must be a lifelike portrayal because Eirene was really a redhead as her original Hungarian name, Piroska shows. The adjacent portrait of Emperor Alexios I Komnenos on a pier (from 1122) is similarly personal. The imperial mausoleum of

8036-462: Is accompanied by a slight expansion of volume. It is used in making casts for statues, toys , and more. The initial matrix consists mostly of orthorhombic crystals: the kinetic product. Over the next 72 hours, the rhombic crystals give way to an interlocking mass of monoclinic crystal needles, and the plaster increases in hardness and strength. If plaster or gypsum is heated to between 130 °C (266 °F) and 180 °C (350 °F), hemihydrate

8232-537: Is an example for conscious archaization as contemporary Byzantine rulers were bearded. A mosaic panel on the gallery shows Christ with Constantine Monomachos and Empress Zoe (1042–1055). The emperor gives a bulging money sack to Christ as a donation for the church. The dome of the Hagia Sophia Church in Thessaloniki is decorated with an Ascension mosaic (c. 885). The composition resembles

8428-525: Is commonly based on the reaction of gypsum plaster with water, where the water is selectively applied by the inkjet head. The chemical reaction that occurs when plaster is mixed with water is exothermic . When plaster sets, it can reach temperatures of more than 60 °C (140 °F) and, in large volumes, can burn the skin. In January 2007, a secondary school student in Lincolnshire , England sustained third-degree burns after encasing her hands in

8624-523: Is done with thin enameled glass and opaque stained glass. Modern mosaic art is made from any material in any size ranging from carved stone, bottle caps, and found objects. The earliest known examples of mosaics made of different materials were found at a temple building in Abra, Mesopotamia , and are dated to the second half of 3rd millennium BC. They consist of pieces of colored stones, shells and ivory. Excavations at Susa and Chogha Zanbil show evidence of

8820-456: Is formed, which will also re-form as gypsum if mixed with water. On heating to 180 °C (350 °F), the nearly water-free form, called γ-anhydrite (CaSO 4 · n H 2 O where n = 0 to 0.05) is produced. γ-anhydrite reacts slowly with water to return to the dihydrate state, a property exploited in some commercial desiccants . On heating above 250 °C (480 °F), the completely anhydrous form called β-anhydrite or dead burned plaster

9016-436: Is formed. Lime plaster is a mixture of calcium hydroxide and sand (or other inert fillers). Carbon dioxide in the atmosphere causes the plaster to set by transforming the calcium hydroxide into calcium carbonate ( limestone ). Whitewash is based on the same chemistry. To make lime plaster, limestone (calcium carbonate) is heated above approximately 850 °C (1600 °F) to produce quicklime (calcium oxide). Water

9212-735: Is generally less durable. Plaster (often called stucco in this context) is a far easier material for making reliefs than stone or wood, and was widely used for large interior wall-reliefs in Egypt and the Near East from antiquity into Islamic times (latterly for architectural decoration, as at the Alhambra ), Rome, and Europe from at least the Renaissance, as well as probably elsewhere. However, it needs very good conditions to survive long in unmaintained buildings – Roman decorative plasterwork

9408-490: Is mainly known from Pompeii and other sites buried by ash from Mount Vesuvius . Plaster may be cast directly into a damp clay mold. In creating this piece molds (molds designed for making multiple copies) or waste molds (for single use) would be made of plaster. This "negative" image, if properly designed, may be used to produce clay productions, which when fired in a kiln become terra cotta building decorations, or these may be used to create cast concrete sculptures. If

9604-477: Is not uniform like sawn lath. The straightness or waviness of the grain affected the thickness or width of each lath, and thus the spacing of the lath. The clay plaster rough coat varied to cover the irregular lath. Window and door trim as well as the mudboard (baseboard) acted as screeds. With the variation of the lath thickness and use of coarse straw and manure, the clay coat of plaster was thick in comparison to later lime-only and gypsum plasters. In Economy Village,

9800-839: Is obvious in the apse mosaic of San Michele in Affricisco , executed in 545–547 (largely destroyed; the remains in Berlin ). The last example of Byzantine mosaics in Ravenna was commissioned by bishop Reparatus between 673 and 679 in the Basilica of Sant'Apollinare in Classe. The mosaic panel in the apse showing the bishop with Emperor Constantine IV is obviously an imitation of the Justinian panel in San Vitale. The mosaic pavement of

9996-594: Is often used as an artistic material for casting. Plaster is also commonly spread over an armature (form), made of wire mesh, cloth, or other materials; a process for adding raised details. For these processes, limestone or acrylic based plaster may be employed, known as stucco. Products composed mainly of plaster of Paris and a small amount of Portland cement are used for casting sculptures and other art objects as well as molds. Considerably harder and stronger than straight plaster of Paris, these products are for indoor use only as they degrade in moist conditions. Plaster

10192-518: Is partially preserved. The so-called Tomb of the Julii , near the crypt beneath St Peter's Basilica , is a 4th-century vaulted tomb with wall and ceiling mosaics that are given Christian interpretations. The Rotunda of Galerius in Thessaloniki , converted into a Christian church during the course of the 4th century, was embellished with very high artistic quality mosaics. Only fragments survive of

10388-435: Is probably the most famous Byzantine mosaic in Constantinople. The Pammakaristos Monastery was restored by Michael Glabas , an imperial official, in the late 13th century. Only the mosaic decoration of the small burial chapel ( parekklesion ) of Glabas survived. This domed chapel was built by his widow, Martha around 1304–08. In the miniature dome the traditional Pantokrator can be seen with twelve prophets beneath. Unusually

10584-533: Is produced by heating gypsum to about 120–180 °C (248–356 °F) in a kiln: CaSO 4 ⋅ 2 H 2 O ⟶ heat CaSO 4 ⋅ 1 2 H 2 O + 1 1 2 H 2 O ↑ {\displaystyle {\ce {CaSO4.2H2O {\overset {heat}{{}->{}}}{CaSO4.1/2H2O}+ 1\!1/2 H2O ^}}} (released as steam). Plaster of Paris has

10780-419: Is stored in moisture -proof containers, because the presence of moisture can cause slow setting of plaster of Paris by bringing about its hydration, which will make it useless after some time. When the dry plaster powder is mixed with water, it rehydrates over time into gypsum. The setting of plaster slurry starts about 10 minutes after mixing and is complete in about 45 minutes. The setting of plaster of Paris

10976-421: Is then added to produce slaked lime (calcium hydroxide), which is sold as a wet putty or a white powder. Additional water is added to form a paste prior to use. The paste may be stored in airtight containers. When exposed to the atmosphere, the calcium hydroxide very slowly turns back into calcium carbonate through reaction with atmospheric carbon dioxide, causing the plaster to increase in strength. Lime plaster

11172-400: Is to replace conventional gypsum plasters in cases where the temperature can get too high for gypsum plaster to stay on the wall or ceiling. An example of a heat-resistant plaster composition is a mixture of Portland cement , gypsum, lime, exfoliated insulating aggregate ( perlite and vermiculite or mica ), phosphate shale , and small amounts of adhesive binder (such as Gum karaya ), and

11368-450: Is used to make dental models by pouring the material into dental impressions . Various types of models and moulds are made with plaster. In art, lime plaster is the traditional matrix for fresco painting; the pigments are applied to a thin wet top layer of plaster and fuse with it so that the painting is actually in coloured plaster. In the ancient world, as well as the sort of ornamental designs in plaster relief that are still used, plaster

11564-503: Is used. The walls are painted with the plaster which (in some countries) is nothing but calcium carbonate. After drying the calcium carbonate plaster turns white and then the wall is ready to be painted. Elsewhere in the world, such as the UK, ever finer layers of plaster are added on top of the plasterboard (or sometimes the brick wall directly) to give a smooth brown polished texture ready for painting. Mural paintings are commonly painted onto

11760-401: Is widely used as a support for broken bones; a bandage impregnated with plaster is moistened and then wrapped around the damaged limb, setting into a close-fitting yet easily removed tube, known as an orthopedic cast . Plaster is also used in preparation for radiotherapy when fabricating individualized immobilization shells for patients. Plaster bandages are used to construct an impression of

11956-421: Is worked in some way to produce relief decoration, rather than flat surfaces. The most common types of plaster mainly contain either gypsum , lime , or cement , but all work in a similar way. The plaster is manufactured as a dry powder and is mixed with water to form a stiff but workable paste immediately before it is applied to the surface. The reaction with water liberates heat through crystallization and

12152-785: The Venus de Milo . A form of Hellenistic architecture arose which especially emphasized the building of grand monuments and ornate decorations, as exemplified by structures such as the Pergamon Altar . The religious sphere of Greek religion expanded through syncretic facets to include new gods such as the Greco-Egyptian Serapis , eastern deities such as Attis and Cybele , and a syncretism between Hellenistic culture and Buddhism in Bactria and Northwest India . Scholars and historians are divided as to which event signals

12348-600: The Basilica of San Lorenzo , mosaics executed in the late 4th and early 5th centuries depict Christ with the Apostles and the Abduction of Elijah ; these mosaics are outstanding for their bright colors, naturalism and adherence to the classical canons of order and proportion. The surviving apse mosaic of the Basilica of Sant'Ambrogio , which shows Christ enthroned between Saint Gervasius and Saint Protasius and angels before

12544-775: The Byzantine Empire from the 6th to the 15th centuries. The majority of Byzantine mosaics were destroyed without trace during wars and conquests, but the surviving remains still form a fine collection. The great buildings of Emperor Justinian like the Hagia Sophia in Constantinople , the Nea Church in Jerusalem and the rebuilt Church of the Nativity in Bethlehem were certainly embellished with mosaics but none of these survived. Important fragments survived from

12740-648: The Greco-Bactrian kingdom ). It can be argued that some of the changes across the Macedonian Empire after Alexander's conquests and during the rule of the Diadochi would have occurred without the influence of Greek rule. As mentioned by Peter Green , numerous factors of conquest have been merged under the term Hellenistic period . Specific areas conquered by Alexander's invading army, including Egypt and areas of Asia Minor and Mesopotamia "fell" willingly to conquest and viewed Alexander as more of

12936-585: The Greek colonies in Illyria. Illyrians imported weapons and armor from the ancient Greeks (such as the Illyrian type helmet , originally a Greek type) and also adopted the ornamentation of ancient Macedon on their shields and their war belts (a single one has been found, dated 3rd century BC at modern Selcë e Poshtme , a part of Macedon at the time under Philip V of Macedon ). The Odrysian Kingdom

13132-686: The Iconoclastic destruction of the 8th century. Among the rare examples are the 6th-century Christ in majesty (or Ezekiel's Vision ) mosaic in the apse of the Church of Hosios David in Thessaloniki that was hidden behind mortar during those dangerous times. Nine mosaic panels in the Hagios Demetrios Church , which were made between 634 and 730, also escaped destruction. Unusually almost all represent Saint Demetrius of Thessaloniki , often with suppliants before him. This iconoclasm

13328-603: The Komnenos dynasty, the Pantokrator Monastery was certainly decorated with great mosaics but these were later destroyed. The lack of Komnenian mosaics outside the capital is even more apparent. There is only a "Communion of the Apostles" in the apse of the cathedral of Serres . A striking technical innovation of the Komnenian period was the production of very precious, miniature mosaic icons. In these icons

Although Eumenes , satrap of Cappadocia , defeated the rebels in Asia Minor, Perdiccas himself was murdered by his own generals Peithon , Seleucus , and Antigenes (possibly with Ptolemy's aid) during his invasion of Egypt ( c.  21 May to 19 June, 320 BC). Ptolemy came to terms with Perdiccas's murderers, making Peithon and Arrhidaeus regents in his place, but soon these came to

This resulted in an influx of Greek colonists and

13916-469: The Mediterranean coast of Provence , France . The first Greek colony in the region was Massalia , which became one of the largest trading ports of Mediterranean by the 4th century BC with 6,000 inhabitants. Massalia was also the local hegemon , controlling various coastal Greek cities like Nice and Agde . The coins minted in Massalia have been found in all parts of Liguro-Celtic Gaul. Celtic coinage

14112-568: The Ptolemaic Kingdom , which might otherwise have been lost, has been preserved in papyrological documents. This is particularly noteworthy given the limited documentation available for their Seleucid counterparts. Ancient Greece had traditionally been a fractious collection of fiercely independent city-states. After the Peloponnesian War (431–404 BC), Greece had fallen under a Spartan hegemony , in which Sparta

However, Emporion lost its political independence around 195 BC with the establishment of the Roman province of Hispania Citerior and by the 1st century BC had become fully Romanized in culture. The Hellenistic states of Asia and Egypt were run by an occupying imperial elite of Greco-Macedonian administrators and governors propped up by

14504-535: The " Nesiotic League " of the Cyclades . These federations involved a central government which controlled foreign policy and military affairs, while leaving most of the local governing to the city states , a system termed sympoliteia . In states such as the Achaean league, this also involved the admission of other ethnic groups into the federation with equal rights, in this case, non- Achaeans . The Achean league

14700-445: The 12th century. The sack of Constantinople in 1204 caused the decline of mosaic art for the next five decades. After the reconquest of the city by Michael VIII Palaiologos in 1261 the Hagia Sophia was restored and a beautiful new Deesis was made on the south gallery. This huge mosaic panel with figures two and a half times lifesize is really overwhelming due to its grand scale and superlative craftsmanship. The Hagia Sophia Deesis

14896-445: The 4th century, still exist. The winemaking putti in the ambulatory of Santa Constanza still follow the classical tradition in that they represent the feast of Bacchus , which symbolizes transformation or change, and are thus appropriate for a mausoleum, the original function of this building. In another great Constantinian basilica, the Church of the Nativity in Bethlehem the original mosaic floor with typical Roman geometric motifs

15092-514: The 5th-century Ravenna , the capital of the Western Roman Empire , became the center of late Roman mosaic art. The Mausoleum of Galla Placidia was decorated with mosaics of high artistic quality in 425–430. The vaults of the small, cross-shaped structure are clad with mosaics on blue background. The central motif above the crossing is a golden cross in the middle of the starry sky. Another great building established by Galla Placidia

15288-720: The 6th to the 15th centuries; that tradition was adopted by the Norman Kingdom of Sicily in the 12th century, by the eastern-influenced Republic of Venice , and among the Rus . Mosaic fell out of fashion in the Renaissance , though artists like Raphael continued to practice the old technique. Roman and Byzantine influence led Jewish artists to decorate 5th and 6th century synagogues in the Middle East with floor mosaics. Figurative mosaic, but mostly without human figures,

15484-740: The Aegean (204–200 BC) and ignored Roman demands for non-intervention in Greece by invading Attica. In 198 BC, during the Second Macedonian War Philip was decisively defeated at Cynoscephalae by the Roman proconsul Titus Quinctius Flamininus and Macedon lost all its territories in Greece proper. Southern Greece was now thoroughly brought into the Roman sphere of influence , though it retained nominal autonomy. The end of Antigonid Macedon came when Philip V's son, Perseus,

15680-530: The Anastasis above the doors, while in the church the Theotokos (apse), Pentecost, scenes from Christ's life and ermit St Loukas (all executed before 1048). The scenes are treated with a minimum of detail and the panels are dominated with the gold setting. The Nea Moni Monastery on Chios was established by Constantine Monomachos in 1043–1056. The exceptional mosaic decoration of the dome showing probably

15876-564: The Apostles. The surviving remains are somewhat fragmented. Massilia remained a thriving port and a Christian spiritual center in Southern Gaul where favourable societal and economic conditions ensured the survival of mosaic art in the 5th and 6th centuries. The large baptistery, once the grandest building of its kind in Western Europe, had a geometric floor mosaic which is only known from 19th century descriptions. Other parts of

16072-816: The Athenians in the Chremonidean War , and then against the Achaean League of Aratus of Sicyon . Under the Antigonids, Macedonia was often short on funds, the Pangaeum mines were no longer as productive as under Philip II, the wealth from Alexander's campaigns had been used up and the countryside pillaged by the Gallic invasion . A large number of the Macedonian population had also been resettled abroad by Alexander or had chosen to emigrate to

16268-577: The Dormition in Nicaea . The crosses were substituted with the image of the Theotokos in both churches after the victory of the Iconodules (787–797 and in 8th–9th centuries respectively, the Dormition church was totally destroyed in 1922). A similar Theotokos image flanked by two archangels were made for the Hagia Sophia in Constantinople in 867. The dedication inscription says: "The images which

16464-633: The Great of the capital of the Roman Empire to Constantinople in AD 330. Though this scope of suggested dates demonstrates a range of academic opinion, a generally accepted date by most of scholarship has been that of 31/30 BC. The word originated from ancient Greek Ἑλληνιστής ( Hellēnistḗs , "one who uses the Greek language"), from Ἑλλάς ( Hellás , "Greece"); as if "Hellenist" + "ic". The idea of

16660-400: The Great died (10 June 323 BC), he left behind a sprawling empire that was composed of many essentially autonomous territories called satrapies . Without a chosen successor, there were immediate disputes among his generals as to who should be king of Macedon. These generals became known as the Diadochi ( ‹See Tfd› Greek : Διάδοχοι , Diadokhoi , meaning "Successors"). Meleager and

16856-643: The Great's Hunt and the Four Seasons . In 1913 the Zliten mosaic , a Roman mosaic famous for its many scenes from gladiatorial contests, hunting and everyday life, was discovered in the Libyan town of Zliten . In 2000 archaeologists working in Leptis Magna , Libya , uncovered a 30 ft length of five colorful mosaics created during the 1st or 2nd century AD. The mosaics show a warrior in combat with

17052-461: The Greek figural style was mostly formed in the 3rd century BC. Mythological subjects, or scenes of hunting or other pursuits of the wealthy, were popular as the centrepieces of a larger geometric design, with strongly emphasized borders. Pliny the Elder mentions the artist Sosus of Pergamon by name, describing his mosaics of the food left on a floor after a feast and of a group of doves drinking from

17248-696: The Greek world, making the endless conflicts between the cities that had marked the 5th and 4th centuries BC seem petty and unimportant. It led to a steady emigration, particularly of the young and ambitious, to the new Greek empires in the east. Many Greeks migrated to Alexandria , Antioch , and the many other new Hellenistic cities founded in Alexander's wake, as far away as modern Afghanistan and Pakistan . Independent city states were unable to compete with Hellenistic kingdoms and were usually forced to ally themselves to one of them for defense, giving honors to Hellenistic rulers in return for protection. One example

17444-635: The Greeks during the 8th century BC. In 4th-century BC Sicily the leading Greek city and hegemon was Syracuse . During the Hellenistic period the leading figure in Sicily was Agathocles of Syracuse (361–289 BC) who seized the city with an army of mercenaries in 317 BC. Agathocles extended his power throughout most of the Greek cities in Sicily, fought a long war with the Carthaginians , at one point invading Tunisia in 310 BC and defeating

17640-577: The Hellenistic period breaks off after the battle of Ipsus (301 BC). Another important source, Plutarch 's ( c.  AD 50  – c.  120 ) Parallel Lives although more preoccupied with issues of personal character and morality, outlines the history of important Hellenistic figures. Appian of Alexandria (late 1st century AD–before 165) wrote a history of the Roman empire that includes information of some Hellenistic kingdoms. Other sources include Justin 's (2nd century AD) epitome of Pompeius Trogus ' Historiae Philipicae and

17836-488: The Hellenistic period is Polybius of Megalopolis (c. 200–118), a statesman of the Achaean League until 168 BC when he was forced to go to Rome as a hostage. His Histories eventually grew to a length of forty books, covering the years 220 to 167 BC. The most important source after Polybius is Diodorus Siculus who wrote his Bibliotheca historica between 60 and 30 BC and reproduced some important earlier sources such as Hieronymus, but his account of

18032-494: The Hellenistic period. Inscriptions on stone or metal were commonly erected throughout the Greek world for public display, a practice which originated well before the time of Alexander the Great, but saw substantial expansion during the Hellenistic Period. The majority of these inscriptions are located on the Greek mainland , the Greek islands , and western Asia Minor . While they become increasingly rare towards

18228-599: The Hellenistic period. It became a center of culture and commerce, its coins were widely circulated and its philosophical schools became one of the best in the Mediterranean. After holding out for one year under siege by Demetrius Poliorcetes (305–304 BC), the Rhodians built the Colossus of Rhodes to commemorate their victory. They retained their independence by the maintenance of a powerful navy, by maintaining

18424-470: The Macedonians themselves were looked down upon as semi-barbaric by the rest of the Greeks. However, Macedon controlled a large area and had a relatively strong centralized government, in comparison to most Greek states. Philip II was a strong and expansionist king who took every opportunity to expand Macedonian territory. In 352 BC he annexed Thessaly and Magnesia . In 338 BC, Philip defeated

18620-612: The Vrina Plain basilica of Butrint , Albania appear to pre-date that of the Baptistery by almost a generation, dating to the last quarter of the 5th or the first years of the 6th century. The mosaic displays a variety of motifs including sea-creatures, birds, terrestrial beasts, fruits, flowers, trees and abstracts – designed to depict a terrestrial paradise of God's creation. Superimposed on this scheme are two large tablets, tabulae ansatae, carrying inscriptions. A variety of fish,

18816-460: The ancient Egyptian bureaucracy, highly centralized and focused on squeezing as much revenue out of the population as possible through tariffs, excise duties, fines, taxes, and so forth. A whole class of petty officials, tax farmers, clerks, and overseers made this possible. The Egyptian countryside was directly administered by this royal bureaucracy. External possessions such as Cyprus and Cyrene were run by strategoi , military commanders appointed by

19012-459: The apse is decorated with a Deesis , probably due to the funerary function of the chapel. Plaster Plaster is a building material used for the protective or decorative coating of walls and ceilings and for moulding and casting decorative elements. In English, "plaster" usually means a material used for the interiors of buildings, while "render" commonly refers to external applications. The term stucco refers to plasterwork that

19208-530: The basilica of Santa Maria Maggiore . The 27 surviving panels of the nave are the most important mosaic cycle in Rome of this period. Two other important 5th century mosaics are lost but we know them from 17th-century drawings. In the apse mosaic of Sant'Agata dei Goti (462–472, destroyed in 1589) Christ was seated on a globe with the twelve Apostles flanking him, six on either side. At Sant'Andrea in Catabarbara (468–483, destroyed in 1686) Christ appeared in

19404-477: The center, flanked on either side by three Apostles. Four streams flowed from the little mountain supporting Christ. The original 5th-century apse mosaic of the Santa Sabina was replaced by a very similar fresco by Taddeo Zuccari in 1559. The composition probably remained unchanged: Christ flanked by male and female saints, seated on a hill while lambs drinking from a stream at its feet. All three mosaics had

19600-442: The city free again. Demetrius now turned his attention to Ptolemy, defeating his fleet at the Battle of Salamis and taking control of Cyprus. In the aftermath of this victory, Antigonus took the title of king ( basileus ) and bestowed it on his son Demetrius Poliorcetes , the rest of the Diadochi soon followed suit. Demetrius continued his campaigns by laying siege to Rhodes and conquering most of Greece in 302 BC, creating

19796-550: The country, especially in the region of the Faiyum . Alexandria , a major center of Greek culture and trade, became his capital city. As Egypt's first port city, it became the main grain exporter in the Mediterranean. The Egyptians begrudgingly accepted the Ptolemies as the successors to the pharaohs of independent Egypt, though the kingdom went through several native revolts. Ptolemy I began to order monetary contributions from

19992-445: The creation of a wax image to be used in lost wax casting , a far more expensive process. In lieu of producing a bronze image suitable for outdoor use the plaster image may be painted to resemble a metal image; such sculptures are suitable only for presentation in a weather-protected environment. Plaster expands while hardening then contracts slightly just before hardening completely. This makes plaster excellent for use in molds, and it

20188-486: The crown. Under Ptolemy II , Callimachus , Apollonius of Rhodes , Theocritus , and a host of other poets including the Alexandrian Pleiad made the city a center of Hellenistic literature. Ptolemy himself was eager to patronise the library, scientific research and individual scholars who lived on the grounds of the library. He and his successors also fought a series of wars with the Seleucids, known as

20384-600: The death of Pyrrhus, Epirus remained a minor power. In 233 BC the Aeacid royal family was deposed and a federal state was set up called the Epirote League . The league was conquered by Rome in the Third Macedonian War (171–168 BC). Antigonus II , a student of Zeno of Citium , spent most of his rule defending Macedon against Epirus and cementing Macedonian power in Greece, first against

20580-665: The decoration scheme first used in Emperor Basil I 's Nea Ekklesia . Not only this prototype was later totally destroyed but each surviving composition is battered so it is necessary to move from church to church to reconstruct the system. An interesting set of Macedonian-era mosaics make up the decoration of the Hosios Loukas Monastery. In the narthex there is the Crucifixion, the Pantokrator and

20776-488: The eastern regions, they are not entirely absent there, and they are most notably featured in public buildings and sanctuaries . The content of these inscriptions is diverse, encompassing royal correspondence addressed to cities or individuals, municipal and legal edicts, decrees commemorating rulers, officials, and individuals for their contributions, as well as laws, treaties, religious rulings, and dedications. Despite challenges in their interpretation, inscriptions are often

20972-570: The empire; no doubt most ordinary craftsmen were slaves. Splendid mosaic floors are found in Roman villas across North Africa , in places such as Carthage , and can still be seen in the extensive collection in Bardo Museum in Tunis , Tunisia . There were two main techniques in Greco-Roman mosaic: opus vermiculatum used tiny tesserae , typically cubes of 4 millimeters or less, and

21168-469: The end of the Hellenistic era. There is a wide chronological range of proposed dates that have included the final conquest of the Greek heartlands by the expansionist Roman Republic in 146 BC following the Achaean War , the final defeat of the Ptolemaic Kingdom at the Battle of Actium in 31 BC, the end of the reign of the Roman emperor Hadrian in AD 138, and the move by the emperor Constantine

21364-423: The episcopal complex were also decorated with mosaics as new finds, that were unearthed in the 2000s, attest. The funerary basilica of Saint Victor , built in a quarry outside the walls, was decorated with mosaics but only a small fragment with blue and green scrolls survived on the intrados of an arch (the basilica was later buried under a medieval abbey). A mosaic pavement depicting humans, animals and plants from

21560-531: The export of Greek culture and language to these new realms, a breadth spanning as far as modern-day India. These new Greek kingdoms were also influenced by regional indigenous cultures, adopting local practices where deemed beneficial, necessary, or convenient. Hellenistic culture thus represents a fusion of the ancient Greek world with that of the Western Asian, Northeastern African, and Southwestern Asian worlds. The consequence of this mixture gave rise to

21756-592: The famous Bikini Girls , showing women undertaking a range of sporting activities in garments that resemble 20th Century bikinis . The peristyle , the imperial apartments and the thermae were also decorated with ornamental and mythological mosaics. Other important examples of Roman mosaic art in Sicily were unearthed on the Piazza Vittoria in Palermo where two houses were discovered. The most important scenes there depicted are an Orpheus mosaic , Alexander

21952-416: The field, along with a group of privileged aristocratic companions or friends ( hetairoi , philoi ) which dined and drank with the king and acted as his advisory council. The monarch was also expected to serve as a charitable patron of the people; this public philanthropy could mean building projects and handing out gifts but also promotion of Greek culture and religion. Ptolemy , a somatophylax , one of

22148-639: The finished product and increase thermal insulation. One differentiates between interior and exterior fireproofing. Interior products are typically less substantial, with lower densities and lower cost. Exterior products have to withstand harsher environmental conditions. A rough surface is typically forgiven inside of buildings as dropped ceilings often hide them. Fireproofing plasters are losing ground to more costly intumescent and endothermic products, simply on technical merit. Trade jurisdiction on unionized construction sites in North America remains with

22344-471: The first glazed tiles, dating from around 1500 BC. However, mosaic patterns were not used until the times of Sassanid Empire and Roman influence. Bronze Age pebble mosaics have been found at Tiryns ; mosaics of the 4th century BC are found in the Macedonian palace-city of Aegae , and the 4th-century BC mosaic of The Beauty of Durrës discovered in Durrës , Albania in 1916, is an early figural example;

22540-615: The great baptistries in Ravenna , with apostles standing between palms and Christ in the middle. The scheme is somewhat unusual as the standard post-Iconoclastic formula for domes contained only the image of the Pantokrator . There are very few existing mosaics from the Komnenian period but this paucity must be due to accidents of survival and gives a misleading impression. The only surviving 12th-century mosaic work in Constantinople

22736-464: The growing power and ambition of Antigonus. He began removing and appointing satraps as if he were king and also raided the royal treasuries in Ecbatana , Persepolis and Susa , making off with 25,000 talents . Seleucus was forced to flee to Egypt and Antigonus was soon at war with Ptolemy, Lysimachus, and Cassander. He then invaded Phoenicia , laid siege to Tyre , stormed Gaza and began building

22932-441: The guise of building rehabilitation." Gypsum plaster, also known as plaster of Paris , is a white powder consisting of calcium sulfate hemihydrate . The natural form of the compound is the mineral bassanite . The name "plaster of Paris" was given because it was originally made by heating gypsum from a large deposit at Montmartre , a hill in the north end of Paris . Gypsum plaster, gypsum powder, or plaster of Paris,

23128-530: The hart panteth after the water brooks, so panteth my soul after thee, O God." Water-birds and fish and other sea-creatures can indicate baptism as well as the members of the Church who are christened. Christian mosaic art also flourished in Rome, gradually declining as conditions became more difficult in the Early Middle Ages . 5th century mosaics can be found over the triumphal arch and in the nave of

23324-514: The house with clay and lime, and to fill, lath, and plaister them with lime and haire besides; and to siele and lath them overhead with lime; also to fill, lath, and plaster the kitchen up to the wall plate on every side. 6. The said Daniel Andrews is to find lime, bricks, clay, stone, haire, together with laborers and workmen." Records of the New Haven colony in 1641 mention clay and hay as well as lime and hair also. In German houses of Pennsylvania

23520-400: The huge territories Alexander had conquered became subject to a strong Greek influence ( Hellenization ) for the next two or three centuries, until the rise of Rome in the west, and of Parthia in the east. As the Greek and Levantine cultures mingled, the development of a hybrid Hellenistic culture began, and persisted even when isolated from the main centres of Greek culture (for instance, in

23716-519: The hydrated plaster then hardens. Plaster can be relatively easily worked with metal tools and sandpaper and can be moulded, either on site or in advance, and worked pieces can be put in place with adhesive . Plaster is suitable for finishing rather than load-bearing, and when thickly applied for decoration may require a hidden supporting framework. Forms of plaster have several other uses. In medicine, plaster orthopedic casts are still often used for supporting set broken bones. In dentistry, plaster

23912-609: The impostors had cast down here pious emperors have again set up." In the 870s the so-called large sekreton of the Great Palace of Constantinople was decorated with the images of the four great iconodule patriarchs. The post-Iconoclastic era was the heyday of Byzantine art with the most beautiful mosaics executed. The mosaics of the Macedonian Renaissance (867–1056) carefully mingled traditionalism with innovation. Constantinopolitan mosaics of this age followed

24108-399: The infantry supported the candidacy of Alexander's half-brother, Philip Arrhidaeus , while Perdiccas , the leading cavalry commander, supported waiting until the birth of Alexander's child by Roxana . After the infantry stormed the palace of Babylon , a compromise was arranged – Arrhidaeus (as Philip III) should become king and should rule jointly with Roxana's child, assuming that it

24304-693: The influence of Byzantine art, noticeable on the mosaics of Santa Prassede , Santa Maria in Domnica , Sant'Agnese fuori le Mura , Santa Cecilia in Trastevere , Santi Nereo e Achilleo and the San Venanzio chapel of San Giovanni in Laterano . The great dining hall of Pope Leo III in the Lateran Palace was also decorated with mosaics. They were all destroyed later except for one example,

24500-436: The interiors of their houses: "Interior plastering in the form of clay antedated even the building of houses of frame, and must have been visible in the inside of wattle filling in those earliest frame houses in which … wainscot had not been indulged. Clay continued in use long after the adoption of laths and brick filling for the frame." Where lime was not easily accessible it was rationed and usually substituted with clay as

24696-655: The language of administration and of the nobility. The nobility also adopted Greek fashions in dress , ornament, and military equipment, spreading it to the other tribes. Thracian kings were among the first to be Hellenized . After 278 BC the Odrysians had a strong competitor in the Celtic Kingdom of Tylis ruled by the kings Comontorius and Cavarus , but in 212 BC they conquered their enemies and destroyed their capital. Southern Italy ( Magna Graecia ) and south-eastern Sicily had been colonized by

24892-599: The latest war between Macedon and the Greek leagues ( the Social War of 220–217 BC) to an end, and at this time he controlled all of Greece except Athens, Rhodes and Pergamum. In 215 BC Philip, with his eye on Illyria , formed an alliance with Rome's enemy Hannibal of Carthage , which led to Roman alliances with the Achaean League , Rhodes and Pergamum. The First Macedonian War broke out in 212 BC, and ended inconclusively in 205 BC. Philip continued to wage war against Pergamum and Rhodes for control of

25088-489: The lime top coats are thin veneers often an eighth inch or less attesting to the scarcity of limestone supplies there. Clay plasters with their lack of tensile and compressive strength fell out of favor as industrial mining and technology advances in kiln production led to the exclusive use of lime and then gypsum in plaster applications. However, clay plasters still exist after hundreds of years clinging to split lath on rusty square nails. The wall variations and roughness reveal

25284-480: The mix. Because plaster of Paris sets quickly, "retardants" were used to slow setting time enough to allow workers to mix large working quantities of lime putty plaster. A modern form of this method uses expanded metal mesh over wood or metal structures, which allows a great freedom of design as it is adaptable to both simple and compound curves. Today this building method has been partly replaced with drywall , also composed mostly of gypsum plaster. In both these methods,

25480-586: The mosaic floor of the Great Palace of Constantinople which was commissioned during Justinian 's reign. The figures, animals, plants all are entirely classical but they are scattered before a plain background. The portrait of a moustached man, probably a Gothic chieftain, is considered the most important surviving mosaic of the Justinianian age. The so-called small sekreton of the palace was built during Justin II 's reign around 565–577. Some fragments survive from

25676-535: The mosaic of the Exaltation of Adam. In the apse the Ascension of Christ. The Annunciation occupies the two pillars next to the altar." The Daphni Monastery houses the best preserved complex of mosaics from the early Comnenan period (ca. 1100) when the austere and hieratic manner typical for the Macedonian epoch and represented by the awesome Christ Pantocrator image inside the dome, was metamorphosing into

25872-719: The mosaics of this vaulted room. The vine scroll motifs are very similar to those in the Santa Constanza and they still closely follow the Classical tradition. There are remains of floral decoration in the Church of the Acheiropoietos in Thessaloniki (5th–6th centuries). In the 6th century, Ravenna , the capital of Byzantine Italy, became the center of mosaic making. Istria also boasts some important examples from this era. The Euphrasian Basilica in Parentium

26068-554: The native population did not always mix; the Greeks moved and brought their own culture, but interaction did not always occur. While a few fragments exist, there are no complete surviving historical works that date to the hundred years following Alexander's death. The works of the major Hellenistic historians Hieronymus of Cardia (who worked under Alexander, Antigonus I and other successors), Duris of Samos and Phylarchus , which were used by surviving sources , are all lost. The earliest and most credible surviving source for

26264-430: The new eastern Greek cities. Up to two-thirds of the population emigrated, and the Macedonian army could only count on a levy of 25,000 men, a significantly smaller force than under Philip II. Antigonus II ruled until his death in 239 BC. His son Demetrius II soon died in 229 BC, leaving a child (Philip V) as king, with the general Antigonus Doson as regent. Doson led Macedon to victory in

26460-415: The nine orders of the angels was destroyed in 1822 but other panels survived (Theotokos with raised hands, four evangelists with seraphim, scenes from Christ's life and an interesting Anastasis where King Salomon bears resemblance to Constantine Monomachos). In comparison with Osios Loukas Nea Moni mosaics contain more figures, detail, landscape and setting. Another great undertaking by Constantine Monomachos

26656-406: The only source available for understanding numerous events in Greek history. Papyrus served as the predominant medium for handwritten documents across the Hellenistic world, though its production was confined to Egypt . Due to Egypt's arid climate , papyrus manuscripts was almost exclusively preserved there as well. That being said, the different historical periods are not represented equally in

26852-517: The original 4th-century cathedral of Aquileia has survived in the later medieval church. This mosaic adopts pagan motifs such as the Nilotic scene, but behind the traditional naturalistic content is Christian symbolism such as the ichthys . The 6th-century early Christian basilicas of Sant' Eufemia it:Basilica di Sant'Eufemia (Grado) and Santa Maria delle Grazie in Grado also have mosaic floors. In

27048-470: The original decoration, especially a band depicting saints with hands raised in prayer, in front of complex architectural fantasies. In the following century Ravenna , the capital of the Western Roman Empire , became the center of late Roman mosaic art (see details in Ravenna section). Milan also served as the capital of the western empire in the 4th century. In the St Aquilinus Chapel of

27244-569: The papyrological documents. Texts from the reign of Ptolemy I are notably scarce, while those from the reign of Ptolemy II are more frequently encountered, this is owing in part to the large quantities of papyri which were stuffed into human and animal mummies during his rule. Papyri have been classified into public and private documents, including literary texts, laws and regulations, official correspondence, petitions , records, and archives or collections of documents belonging to individuals of position and authority. Significant information about

27440-491: The people and, as a result, rewarded cities with high contributions with royal benefaction. This often resulted in the formation of a royal cult within the city. Reservations about this activity slowly dissipated as this worship of mortals was justified by the precedent of the worshipping of Greek heroes. The Ptolemies took on the traditions of the Egyptian Pharaohs , such as marrying their siblings ( Ptolemy II

27636-403: The plasterers, regardless of whether the plaster is decorative in nature or is used in passive fire protection. Cementitious and gypsum based plasters tend to be endothermic. Fireproofing plasters are closely related to firestop mortars. Most firestop mortars can be sprayed and tooled very well, due to the fine detail work that is required of firestopping. Powder bed and inkjet head 3D printing

27832-575: The pope with a model of the church (destroyed in 1607). The fragment of an 8th-century mosaic, the Epiphany is one of the very rare remaining pieces of the medieval decoration of Old St. Peter's Basilica , demolished in the late 16th century. The precious fragment is kept in the sacristy of Santa Maria in Cosmedin . It proves the high artistic quality of the destroyed St. Peter's mosaics. Mosaics were more central to Byzantine culture than to that of Western Europe. Byzantine church interiors were generally covered with golden mosaics. Mosaic art flourished in

28028-400: The powder form is converted in a sheet form and the sheet is then attached to the basic ceiling with the help of fasteners. It is done in various designs containing various combinations of lights and colors. The common use of this plaster can be seen in the construction of houses. Post-construction, direct painting is possible (which is commonly seen in French architecture), but elsewhere plaster

28224-401: The principal door from the narthex we can see an Emperor kneeling before Christ (late 9th or early 10th century). Above the door from the southwest vestibule to the narthex another mosaic shows the Theotokos with Justinian and Constantine . Justinian I is offering the model of the church to Mary while Constantine is holding a model of the city in his hand. Both emperors are beardless – this

28420-428: The remnants of his rule, thereby recapturing a rebellious Athens. Meanwhile, Lysimachus took over Ionia , Seleucus took Cilicia , and Ptolemy captured Cyprus . After Cassander's death in c.  298 BC , however, Demetrius, who still maintained a sizable loyal army and fleet, invaded Macedon, seized the Macedonian throne (294 BC) and conquered Thessaly and most of central Greece (293–291 BC). He

28616-408: The richness of God's creation; some elements also have specific connotations. The kantharos vase and vine refer to the eucharist , the symbol of the sacrifice of Christ leading to salvation. Peacocks are symbols of paradise and resurrection; shown eating or drinking from the vase they indicate the route to eternal life. Deer or stags were commonly used as images of the faithful aspiring to Christ: "As

28812-408: The rise of New Comedy , Alexandrian poetry , translation efforts such as the Septuagint , and the philosophies of Stoicism , Epicureanism , and Pyrrhonism . In science, the works of the mathematician Euclid and the polymath Archimedes are exemplary. Sculpture during this period was characterized by intense emotion and dynamic movement, as seen in sculptural works like the Dying Gaul and

29008-415: The second half of the 5th century. Saint Victor is depicted in the center of the golden dome, while figures of saints are shown on the walls before a blue background. The low spandrels give space for the symbols of the four Evangelists. Albingaunum was the main Roman port of Liguria . The octagonal baptistery of the town was decorated in the 5th century with high quality blue and white mosaics representing

29204-433: The second half of the 6th century. Outstanding examples of Byzantine mosaic art are the later phase mosaics in the Basilica of San Vitale and Basilica of Sant'Apollinare Nuovo. The mosaic depicting Emperor Saint Justinian I and Empress Theodora in the Basilica of San Vitale were executed shortly after the Byzantine conquest. The mosaics of the Basilica of Sant'Apollinare in Classe were made around 549. The anti-Arian theme

29400-420: The seven bodyguards who served as Alexander the Great 's generals and deputies, was appointed satrap of Egypt after Alexander's death in 323 BC. In 305 BC, he declared himself King Ptolemy I, later known as "Soter" (saviour) for his role in helping the Rhodians during the siege of Rhodes . Ptolemy built new cities such as Ptolemais Hermiou in upper Egypt and settled his veterans throughout

29596-404: The small tesserae (with sides of 1 mm or less) were set on wax or resin on a wooden panel. These products of extraordinary craftmanship were intended for private devotion. The Louvre Transfiguration is a very fine example from the late 12th century. The miniature mosaic of Christ in the Museo Nazionale at Florence illustrates the more gentle, humanistic conception of Christ which appeared in

29792-420: The so-called Triclinio Leoniano of which a copy was made in the 18th century. Another great work of Pope Leo, the apse mosaic of Santa Susanna , depicted Christ with the Pope and Charlemagne on one side, and SS. Susanna and Felicity on the other. It was plastered over during a renovation in 1585. Pope Paschal I (817–824) embellished the church of Santo Stefano del Cacco with an apsidal mosaic which depicted

29988-407: The spread of Greek culture was not the generalized phenomenon that the term implies. Some areas of the conquered world were more affected by Greek influences than others. The term Hellenistic also implies that the Greek populations were of majority in the areas in which they settled, but in many cases, the Greek settlers were actually the minority among the native populations. The Greek population and

30184-444: The term Hellenistic to refer to and define the period when Greek culture spread in the non-Greek world after Alexander's conquest. Following Droysen, Hellenistic and related terms, e.g. Hellenism , have been widely used in various contexts; a notable such use is in Culture and Anarchy by Matthew Arnold , where Hellenism is used in contrast with Hebraism . The major issue with the term Hellenistic lies in its convenience, as

30380-431: The title of king. Athens later allied itself to Ptolemaic Egypt to throw off Macedonian rule, eventually setting up a religious cult for the Ptolemaic kings and naming one of the city's phyles in honour of Ptolemy for his aid against Macedon. In spite of the Ptolemaic monies and fleets backing their endeavors, Athens and Sparta were defeated by Antigonus II during the Chremonidean War (267–261 BC). Athens

30576-450: The tradition in the 6th century, as the mosaics of the Arian Baptistry , Baptistry of Neon , Archbishop's Chapel , and the earlier phase mosaics in the Basilica of San Vitale and Basilica of Sant'Apollinare Nuovo testify. After 539, Ravenna was reconquered by the Romans in the form of the Eastern Roman Empire (Byzantine Empire) and became the seat of the Exarchate of Ravenna . The greatest development of Christian mosaics unfolded in

30772-426: The tripartite territorial division of the Hellenistic age was in place, with the main Hellenistic powers being Macedon under Demetrius's son Antigonus II Gonatas , the Ptolemaic kingdom under Ptolemy 's son Ptolemy II and the Seleucid empire under Seleucus' son Antiochus I Soter . Epirus was a northwestern Greek kingdom in the western Balkans ruled by the Molossian Aeacidae dynasty. Epirus

30968-472: The use of clay persisted. Old Economy Village is one such German settlement. The early Nineteenth-Century utopian village in present-day Ambridge , Pennsylvania, used clay plaster substrate exclusively in the brick and wood frame high architecture of the Feast Hall, Great House and other large and commercial structures as well as in the brick, frame and log dwellings of the society members. The use of clay in plaster and in laying brickwork appears to have been

31164-438: The war against the Spartan king Cleomenes III , and occupied Sparta . Philip V , who came to power when Doson died in 221 BC, was the last Macedonian ruler with both the talent and the opportunity to unite Greece and preserve its independence against the "cloud rising in the west": the ever-increasing power of Rome. He was known as "the darling of Hellas". Under his auspices the Peace of Naupactus (217 BC) brought

31360-582: The wax melts and flows out) and the denture materials are injected into the mold. After a curing period, the mold is opened and the dentures are cleaned up and polished. Plasters have been in use in passive fire protection , as fireproofing products, for many decades. Gypsum plaster releases water vapor when exposed to flame, acting to slow the spread of the fire, for as much as an hour or two depending on thickness. Plaster also provides some insulation to retard heat flow into structural steel elements, that would otherwise lose their strength and collapse in

31556-422: The world, and are protected as a UNESCO World Heritage Site . The large villa rustica , which was probably owned by Emperor Maximian , was built largely in the early 4th century. The mosaics were covered and protected for 700 years by a landslide that occurred in the 12th Century. The most important pieces are the Circus Scene , the 64m long Great Hunting Scene , the Little Hunt , the Labours of Hercules and

31752-503: The world. Many materials other than traditional stone, ceramic tesserae, enameled and stained glass may be employed, including shells, beads, charms, chains, gears, coins, and pieces of costume jewelry. Traditional mosaics are made of small cubes of roughly square pieces of stone or hand made glass enamel of different colours, known as tesserae . Some of the earliest mosaics were made of natural pebbles, originally used to reinforce floors. Mosaic skinning (covering objects with mosaic glass)

31948-421: Was a boy (as it was, becoming Alexander IV ). Perdiccas himself would become regent ( epimeletes ) of the empire, and Meleager his lieutenant. Soon, however, Perdiccas had Meleager and the other infantry leaders murdered and assumed full control. The generals who had supported Perdiccas were rewarded in the partition of Babylon by becoming satraps of the various parts of the empire, but Perdiccas' position

32144-431: Was a common building material for wall surfaces in a process known as lath and plaster , whereby a series of wooden strips on a studwork frame was covered with a semi-dry plaster that hardened into a surface. The plaster used in most lath and plaster construction was mainly lime plaster , with a cure time of about a month. To stabilize the lime plaster during curing, small amounts of plaster of Paris were incorporated into

32340-548: Was a union of Thracian tribes under the kings of the powerful Odrysian tribe. Various parts of Thrace were under Macedonian rule under Philip II of Macedon , Alexander the Great , Lysimachus , Ptolemy II , and Philip V but were also often ruled by their own kings. The Thracians and Agrianes were widely used by Alexander as peltasts and light cavalry , forming about one-fifth of his army. The Diadochi also used Thracian mercenaries in their armies and they were also used as colonists. The Odrysians used Greek as

32536-403: Was able to drive out the Macedonians from the Peloponnese and free Corinth, which duly joined the league. One of the few city states who managed to maintain full independence from the control of any Hellenistic kingdom was Rhodes . With a skilled navy to protect its trade fleets from pirates and an ideal strategic position covering the routes from the east into the Aegean, Rhodes prospered during

32732-400: Was almost certainly because of nearby Muslims' beliefs. In the Iconoclastic era , figural mosaics were also condemned as idolatry. The Iconoclastic churches were embellished with plain gold mosaics with only one great cross in the apse like the Hagia Irene in Constantinople (after 740). There were similar crosses in the apses of the Hagia Sophia Church in Thessaloniki and in the Church of

32928-483: Was also a center of education, where Celts went to learn Greek. A staunch ally of Rome, Massalia retained its independence until it sided with Pompey in 49 BC and was then taken by Caesar's forces . The city of Emporion (modern Empúries ), originally founded by Archaic-period settlers from Phocaea and Massalia in the 6th century BC near the village of Sant Martí d'Empúries (located on an offshore island that forms part of L'Escala , Catalonia , Spain ),

33124-420: Was also widely used to create large figurative reliefs for walls, though few of these have survived. Plaster was first used as a building material and for decoration in the Middle East at least 7,000 years ago. In Egypt, gypsum was burned in open fires, crushed into powder, and mixed with water to create plaster, used as a mortar between the blocks of pyramids and to provide a smooth wall facing. In Jericho,

33320-425: Was an ally of Macedon during the reigns of Philip II and Alexander. In 281 Pyrrhus (nicknamed "the eagle", aetos ) invaded southern Italy to aid the city state of Tarentum . Pyrrhus defeated the Romans in the Battle of Heraclea and at the Battle of Asculum . Though victorious, he was forced to retreat due to heavy losses, hence the term " Pyrrhic victory ". Pyrrhus then turned south and invaded Sicily but

33516-477: Was assassinated by Ptolemy Ceraunus ("the thunderbolt"), who had taken refuge at the Seleucid court and then had himself acclaimed as king of Macedon. Ptolemy was killed when Macedon was invaded by Gauls in 279 BC —his head stuck on a spear—and the country fell into anarchy. Antigonus II Gonatas invaded Thrace in the summer of 277 and defeated a large force of 18,000 Gauls. He was quickly hailed as king of Macedon and went on to rule for 35 years. At this point

33712-530: Was assassinated. Succeeding his father, Alexander took over the Persian war himself. During a decade of campaigning, Alexander conquered the whole Persian Empire , overthrew the Persian king Darius III . The conquered lands included Asia Minor , Assyria , the Levant , Egypt , Mesopotamia , Media , Persia , and parts of modern-day Afghanistan , Pakistan , and the steppes of central Asia. The years of constant campaigning had taken their toll, however, and Alexander died in 323 BC. After his death,

33908-404: Was because of its low cost, but also the availability. At Economy, root cellars dug under the houses yielded clay and sand (stone), or the nearby Ohio river yielded washed sand from the sand bars; and lime outcroppings and oyster shell for the lime kiln . The surrounding forests of the new village of Economy provided straight grain, old- growth oak trees for lath. Hand split lath starts with

34104-414: Was built in the middle of the 6th century and decorated with mosaics depicting the Theotokos flanked by angels and saints. Fragments remain from the mosaics of the Church of Santa Maria Formosa in Pola . These pieces were made during the 6th century by artists from Constantinople. Their pure Byzantine style is different from the contemporary Ravennate mosaics. Very few early Byzantine mosaics survived

34300-404: Was called asaroton (Greek for "unswept floor"). It depicted in trompe-l'œil style the feast leftovers on the floors of wealthy houses. With the building of Christian basilicas in the late 4th century, wall and ceiling mosaics were adopted for Christian uses. The earliest examples of Christian basilicas have not survived, but the mosaics of Santa Constanza and Santa Pudenziana , both from

34496-400: Was crushed at the Battle of Sellasia (222 BC) by the Achaean league and Macedon, who restored the power of the ephors . Other city states formed federated states in self-defense, such as the Aetolian League ( est. 370 BC), the Achaean League ( est. 280 BC), the Boeotian league , the "Northern League" ( Byzantium , Chalcedon , Heraclea Pontica and Tium ) and

34692-405: Was defeated and captured by the Romans in the Third Macedonian War (171–168 BC). During the Hellenistic period, the importance of Greece proper within the Greek-speaking world declined sharply. The great centers of Hellenistic culture were Alexandria and Antioch , capitals of Ptolemaic Egypt and Seleucid Syria respectively. The conquests of Alexander greatly widened the horizons of

34888-570: Was defeated in 288 BC when Lysimachus of Thrace and Pyrrhus of Epirus invaded Macedon on two fronts, and quickly carved up the kingdom for themselves. Demetrius fled to central Greece with his mercenaries and began to build support there and in the northern Peloponnese. He once again laid siege to Athens after they turned on him, but then struck a treaty with the Athenians and Ptolemy, which allowed him to cross over to Asia Minor and wage war on Lysimachus' holdings in Ionia , leaving his son Antigonus Gonatas in Greece. After initial successes, he

35084-409: Was first introduced in America around 1909 and was often called by the generic name adamant plaster after a prominent manufacturer of the time. The advantages of cement plaster noted at that time were its strength, hardness, quick setting time and durability. Heat-resistant plaster is a building material used for coating walls and chimney breasts and for use as a fire barrier in ceilings. Its purpose

35280-400: Was forced to surrender to Seleucus in 285 BC and later died in captivity. Lysimachus, who had seized Macedon and Thessaly for himself, was forced into war when Seleucus invaded his territories in Asia Minor and was defeated and killed in 281 BC at the Battle of Corupedium , near Sardis . Seleucus then attempted to conquer Lysimachus' European territories in Thrace and Macedon, but he

35476-463: Was influenced by Greek designs, and Greek letters can be found on various Celtic coins, especially those of Southern France . Traders from Massalia ventured inland deep into France on the Rivers Durance and Rhône , and established overland trade routes deep into Gaul , and to Switzerland and Burgundy . The Hellenistic period saw the Greek alphabet spread into southern Gaul from Massalia (3rd and 2nd centuries BC) and according to Strabo , Massalia

35672-452: Was inhabited by various Illyrian tribes and kingdoms such as the kingdom of the Dalmatae and of the Ardiaei , who often engaged in piracy under Queen Teuta (reigned 231–227 BC). Further inland was the Illyrian Paeonian Kingdom and the tribe of the Agrianes . Illyrians on the coast of the Adriatic were under the effects and influence of Hellenisation and some tribes adopted Greek, becoming bilingual due to their proximity to

35868-426: Was joined by Eumenes) and was supported by Antigonus, Lysimachus and Ptolemy. In 317 BC, Cassander invaded Macedonia, attaining control of Macedon, sentencing Olympias to death and capturing the boy king Alexander IV , and his mother. In Asia, Eumenes was betrayed by his own men after years of campaign and was given up to Antigonus who had him executed. The third war of the Diadochi broke out because of

36064-437: Was laid on site. There was a distinct native Italian style using black on a white background, which was no doubt cheaper than fully coloured work. In Rome, Nero and his architects used mosaics to cover some surfaces of walls and ceilings in the Domus Aurea , built 64 AD, and wall mosaics are also found at Pompeii and neighbouring sites. However it seems that it was not until the Christian era that figural wall mosaics became

36260-468: Was pre-eminent but not all-powerful. Spartan hegemony was succeeded by a Theban hegemony after the Battle of Leuctra (371 BC), but after the Battle of Mantinea (362 BC) , all of Greece was so weakened that no one state could claim pre-eminence. It was against this backdrop that the ascendancy of Macedon began, under king Philip II . Macedon was located at the periphery of the Greek world, and although its royal family claimed Greek descent,

36456-417: Was produced in workshops in relatively small panels which were transported to the site glued to some temporary support. The tiny tesserae allowed very fine detail, and an approach to the illusionism of painting. Often small panels called emblemata were inserted into walls or as the highlights of larger floor-mosaics in coarser work. The normal technique was opus tessellatum , using larger tesserae, which

36652-413: Was reestablished in the 5th century BC with a new city ( neapolis ) on the Iberian mainland . Emporion contained a mixed population of Greek colonists and Iberian natives, and although Livy and Strabo assert that they lived in different quarters , these two groups were eventually integrated. The city became a dominant trading hub and center of Hellenistic civilization in Iberia, eventually siding with

36848-413: Was shaky because, as Arrian writes, "everyone was suspicious of him, and he of them". The first of the Diadochi wars broke out when Perdiccas planned to marry Alexander's sister Cleopatra and began to question Antigonus I Monophthalmus ' leadership in Asia Minor . Antigonus fled for Greece, and then, together with Antipater and Craterus (the satrap of Cilicia who had been in Greece fighting

37044-448: Was the church of San Giovanni Evangelista . She erected it in fulfillment of a vow that she made having escaped from a deadly storm in 425 on the sea voyage from Constantinople to Ravenna. The mosaics depicted the storm, portraits of members of the western and eastern imperial family and the bishop of Ravenna, Peter Chrysologus . They are known only from Renaissance sources because almost all were destroyed in 1747. Ostrogoths kept alive

37240-457: Was the first to adopt this custom), having themselves portrayed on public monuments in Egyptian style and dress, and participating in Egyptian religious life. The Ptolemaic ruler cult portrayed the Ptolemies as gods, and temples to the Ptolemies were erected throughout the kingdom. Ptolemy I even created a new god, Serapis , who was a combination of two Egyptian gods: Apis and Osiris, with attributes of Greek gods . Ptolemaic administration was, like

37436-425: Was the restoration of the Church of the Holy Sepulchre in Jerusalem between 1042 and 1048. Nothing survived of the mosaics which covered the walls and the dome of the edifice but the Russian abbot Daniel, who visited Jerusalem in 1106–1107 left a description: "Lively mosaics of the holy prophets are under the ceiling, over the tribune. The altar is surmounted by a mosaic image of Christ. In the main altar one can see

37632-491: Was then occupied by Macedonian troops, and run by Macedonian officials. Sparta remained independent, but it was no longer the leading military power in the Peloponnese . The Spartan king Cleomenes III (235–222 BC) staged a military coup against the conservative ephors and pushed through radical social and land reforms in order to increase the size of the shrinking Spartan citizenry able to provide military service and restore Spartan power. Sparta's bid for supremacy

37828-404: Was unsuccessful and returned to Italy. After the Battle of Beneventum (275 BC) Pyrrhus lost all his Italian holdings and left for Epirus. Pyrrhus then went to war with Macedonia in 275 BC, deposing Antigonus II Gonatas and briefly ruling over Macedonia and Thessaly until 272. Afterwards, he invaded southern Greece and was killed in battle against Argos in 272 BC. After

38024-426: Was used as reinforcement. In the Earliest European settlers' plasterwork, a mud plaster was used McKee wrote, of a circa 1675 Massachusetts contract that specified the plasterer, "Is to lath and siele the four rooms of the house betwixt the joists overhead with a coat of lime and haire upon the clay; also to fill the gable ends of the house with ricks and plaister them with clay. 5. To lath and plaster partitions of

38220-424: Was used on interior walls and ceilings as well as exterior walls as the wall cavity and exterior cladding isolated the clay plaster from moisture penetration. Application of clay plaster in brick structures risked water penetration from failed mortar joints on the exterior brick walls. In Economy Village, the rear and middle wythes of brick dwelling walls are laid in a clay and sand mortar with the front wythe bedded in

38416-442: Was widely used on religious buildings and palaces in early Islamic art , including Islam's first great religious building, the Dome of the Rock in Jerusalem , and the Umayyad Mosque in Damascus . Such mosaics went out of fashion in the Islamic world after the 8th century, except for geometrical patterns in techniques such as zellij , which remain popular in many areas. Modern mosaics are made by artists and craftspeople around
