102-673: The Pont Alexandre III is a deck arch bridge that spans the Seine in Paris . It connects the Champs-Élysées quarter with those of the Invalides and Eiffel Tower . The bridge is widely regarded as the most ornate, extravagant bridge in the city. It has been classified as a French monument historique since 1975. The Beaux-Arts style bridge, with its exuberant Art Nouveau lamps, cherubs , nymphs and winged horses at both ends,

204-537: A certain Tawagalawa , a possible Hittite rendering of the Greek name Eteocles , as brother of the king of Ahhiyawa. In c. 1250 BC, the first wave of destruction apparently occurred in various centres of mainland Greece for reasons that cannot be identified by archaeologists. In Boeotia , Thebes was burned to the ground, around that year or slightly later. Nearby Orchomenos was not destroyed at this time but

306-512: A deck arch bridge. Any part supported from arch below may have spandrels that are closed or open. The Sydney Harbour Bridge and the Bayonne Bridge are a through arch bridge which uses a truss type arch. Also known as a bowstring arch, this type of arch bridge incorporates a tie between two opposite ends of the arch. The tie is usually the deck and is capable of withstanding the horizontal thrust forces which would normally be exerted on

408-734: A fresco at Akrotiri , on Thera island, which possibly displays many warriors in boar's tusk helmets , a feature typical of Mycenaean warfare. In the early 15th century BC, commerce intensified with Mycenaean pottery reaching the western coast of Asia Minor , including Miletus and Troy , Cyprus , Lebanon , Palestine and Egypt . Early Mycenaean civilization from the Shaft Grave period generally showcases heavy influence from Minoan Crete in regards to e.g. art, infrastructure and symbols, while also maintaining some Helladic elements as well as some innovations, and some West Asian influences. A difference between Mycenaean and Minoan civilizations

510-609: A length of 167 feet (51 m) and span of 123 feet (37 m), is the world's first wholly stone open-spandrel segmental arch bridge, allowing a greater passage for flood waters. Bridges with perforated spandrels can be found worldwide, such as in China ( Zhaozhou Bridge , 7th century). Greece ( Bridge of Arta , 17th century) and Wales ( Cenarth Bridge , 18th century). In more modern times, stone and brick arches continued to be built by many civil engineers, including Thomas Telford , Isambard Kingdom Brunel and John Rennie . A key pioneer

612-634: A more sophisticated sociopolitical culture of their own. The most prominent site was Mycenae , after which the culture of this era is named. Other centers of power that emerged included Pylos , Tiryns , and Midea in the Peloponnese , Orchomenos , Thebes , and Athens in Central Greece , and Iolcos in Thessaly . Mycenaean settlements also appeared in Epirus , Macedonia , on islands in

714-445: A person, Enkhelyawon , at Pylos, who appears titleless in the written record but whom modern scholars regard as probably a king. A number of local officials positioned by the wanax appear to be in charge of the districts, such as ko-re-te ( koreter , '"governor"), po-ro-ko-re-te ( prokoreter , "deputy") and the da-mo-ko-ro ( damokoros , "one who takes care of a damos"), the latter probably being appointed to take charge of

816-566: A political reconstruction of Bronze Age Greece. Excavations at Miletus, southwest Asia Minor , indicate the existence of a Mycenaean settlement there already from c.  1450 BC , replacing the previous Minoan installations. This site became a sizable and prosperous Mycenaean center until the 12th century BC. Apart from the archaeological evidence, this is also attested in Hittite records, which indicate that Miletos (Milawata in Hittite)

918-448: A quantity of fill material (typically compacted rubble) above the arch in order to increase this dead-weight on the bridge and prevent tension from occurring in the arch ring as loads move across the bridge. Other materials that were used to build this type of bridge were brick and unreinforced concrete. When masonry (cut stone) is used the angles of the faces are cut to minimize shear forces. Where random masonry (uncut and unprepared stones)

1020-415: A result, masonry arch bridges are designed to be constantly under compression, so far as is possible. Each arch is constructed over a temporary falsework frame, known as a centring . In the first compression arch bridges, a keystone in the middle of the bridge bore the weight of the rest of the bridge. The more weight that was put onto the bridge, the stronger its structure became. Masonry arch bridges use

1122-523: A straight entry passage lined with stone. Starting in the 15th century BC, the Mycenaeans began to spread their influence throughout the Aegean and Western Anatolia. By c.  1450 BC , the palace of Knossos was ruled by a Mycenaean elite who formed a hybrid Minoan-Mycenaean culture. Mycenaeans also colonized several other Aegean islands, reaching as far as Rhodes . Thus the Mycenaeans became

1224-454: A substantial part still standing and even used to carry vehicles. A more complete survey by the Italian scholar Vittorio Galliazzo found 931 Roman bridges, mostly of stone, in as many as 26 countries (including former Yugoslavia ). Roman arch bridges were usually semicircular , although a number were segmental arch bridges (such as Alconétar Bridge ), a bridge which has a curved arch that

1326-430: A three-hinged bridge has hinged in all three locations. Most modern arch bridges are made from reinforced concrete . This type of bridge is suitable where a temporary centring may be erected to support the forms, reinforcing steel, and uncured concrete. When the concrete is sufficiently set the forms and falseworks are then removed. It is also possible to construct a reinforced concrete arch from precast concrete , where

1428-541: A trade embargo imposed on Assyria. In general, in the second half of 13th century BC, trade was in decline in the Eastern Mediterranean, most probably due to the unstable political environment there. None of the defence measures appear to have prevented the final destruction and collapse of the Mycenaean states. A second destruction struck Mycenae in c. 1190 BC or shortly thereafter. This event marked

1530-613: A triangular corbel arch. The 4th century BC Rhodes Footbridge rests on an early voussoir arch. Although true arches were already known by the Etruscans and ancient Greeks , the Romans were – as with the vault and the dome – the first to fully realize the potential of arches for bridge construction. A list of Roman bridges compiled by the engineer Colin O'Connor features 330 Roman stone bridges for traffic, 34 Roman timber bridges and 54 Roman aqueduct bridges ,

1632-428: Is a masonry, or stone, bridge where each successively higher course (layer) cantilevers slightly more than the previous course. The steps of the masonry may be trimmed to make the arch have a rounded shape. The corbel arch does not produce thrust, or outward pressure at the bottom of the arch, and is not considered a true arch . It is more stable than a true arch because it does not have this thrust. The disadvantage

1734-453: Is complexity and monumentality; Mycenaean craftmanship and architecture are more simplified versions of Minoan ones, but are more monumental in size. Later phases of the Mycenaean civilization showcase more sophistication, eventually coming to surpass Minoan Crete after a few centuries. At the end of the Shaft Grave era, a new and more imposing type of elite burial emerged, the tholos : large circular burial chambers with high vaulted roofs and

1836-622: Is generally accepted as a Hittite term for Mycenaean Greece ( Achaeans in Homeric Greek), but a precise geographical definition of the term cannot be drawn from the texts. During this time, the kings of Ahhiyawa were evidently capable of dealing with their Hittite counterparts both on a diplomatic and military level. Moreover, Ahhiyawa achieved considerable political influence in parts of Western Anatolia, typically by encouraging anti-Hittite uprisings and collaborating with local vassal rulers. In c.  1400 BC , Hittite records mention

1938-452: Is less than a semicircle. The advantages of the segmental arch bridge were that it allowed great amounts of flood water to pass under it, which would prevent the bridge from being swept away during floods and the bridge itself could be more lightweight. Generally, Roman bridges featured wedge-shaped primary arch stones ( voussoirs ) of the same in size and shape. The Romans built both single spans and lengthy multiple arch aqueducts , such as

2040-524: Is no satisfactory explanation for the collapse of the Mycenaean palace systems. The two most common theories are population movement and internal conflict. The first attributes the destruction of Mycenaean sites to invaders. The hypothesis of a Dorian invasion , known as such in Ancient Greek tradition , that led to the end of Mycenaean Greece, is supported by sporadic archaeological evidence such as new types of burials, in particular cist graves, and

2142-489: Is not able to solve the issue and that the majority of Hellenists believed Mycenaeans spoke a non-Indo-European Minoan language before Linear B was deciphered in 1952. Notwithstanding the above academic disputes, the mainstream consensus among modern Mycenologists is that Mycenaean civilization began around 1750 BC, earlier than the Shaft Graves, originating and evolving from the local socio-cultural landscape of

2244-432: Is that this type of arch is not suitable for large spans. In some locations it is necessary to span a wide gap at a relatively high elevation, such as when a canal or water supply must span a valley. Rather than building extremely large arches, or very tall supporting columns (difficult using stone), a series of arched structures are built one atop another, with wider structures at the base. Roman civil engineers developed

2346-402: Is used they are mortared together and the mortar is allowed to set before the falsework is removed. Traditional masonry arches are generally durable, and somewhat resistant to settlement or undermining. However, relative to modern alternatives, such bridges are very heavy, requiring extensive foundations . They are also expensive to build wherever labor costs are high. The corbel arch bridge

2448-594: The Aegean Sea , on the south-west coast of Asia Minor , and on Cyprus , while Mycenaean-influenced settlements appeared in the Levant and Italy . The Mycenaean Greeks introduced several innovations in the fields of engineering, architecture and military infrastructure , while trade over vast areas of the Mediterranean was essential for the Mycenaean economy. Their syllabic script , Linear B , offers

2550-610: The Alcántara Bridge . The Romans also introduced segmental arch bridges into bridge construction. The 330 m-long (1,080 ft) Limyra Bridge in southwestern Turkey features 26 segmental arches with an average span-to-rise ratio of 5.3:1, giving the bridge an unusually flat profile unsurpassed for more than a millennium. Trajan's bridge over the Danube featured open- spandrel segmental arches made of wood (standing on 40 m-high (130 ft) concrete piers). This

2652-550: The Dorian invasion or activities connected to the " Sea Peoples ". Additional theories such as natural disasters and climatic changes have also been suggested. The Mycenaean period became the historical setting of much ancient Greek literature and mythology , including the Trojan Epic Cycle . The Bronze Age in mainland Greece is generally termed as the " Helladic period " by modern archaeologists, after Hellas ,

2754-615: The Early and Middle Bronze Age in mainland Greece with influences from Minoan Crete . Towards the end of the Middle Bronze Age ( c.  1700 /1675 BC), a significant increase in the population and the number of settlements occurred. A number of centers of power emerged in southern mainland Greece dominated by a warrior elite society; while the typical dwellings of that era were an early type of megaron buildings, some more complex structures are classified as forerunners of

2856-525: The Levantine coast. Nevertheless, other regions on the edge of the Mycenaean world prospered, such as the Ionian islands , the northwestern Peloponnese, parts of Attica and a number of Aegean islands. The acropolis of Athens , oddly, appears to have avoided destruction. Athens and the eastern coast of Attica were still occupied in the 12th century BC, and were not destroyed or abandoned; this points to

2958-683: The Pont du Gard and Segovia Aqueduct . Their bridges featured from an early time onwards flood openings in the piers, e.g. in the Pons Fabricius in Rome (62 BC), one of the world's oldest major bridges still standing. Roman engineers were the first and until the Industrial Revolution the only ones to construct bridges with concrete , which they called Opus caementicium . The outside was usually covered with brick or ashlar , as in

3060-453: The Pylos archive, which is the best preserved one in the Mycenaean world, is generally taken as a representative one. The state was ruled by a king, the wanax (ϝάναξ), whose role was religious and perhaps also military and judicial. The wanax oversaw virtually all aspects of palatial life, from religious feasting and offerings to the distribution of goods, craftsmen and troops. Under him

3162-703: The Venetian Rialto bridge and the Fleischbrücke in Nuremberg (span-to-rise ratio 6.4:1) were founded on thousands of wooden piles, partly rammed obliquely into the grounds to counteract more effectively the lateral thrust. In China, the oldest existing arch bridge is the Zhaozhou Bridge of 605 AD, which combined a very low span-to-rise ratio of 5.2:1, with the use of spandrel arches (buttressed with iron brackets). The Zhaozhou Bridge, with

3264-467: The collapse of Bronze Age culture in the eastern Mediterranean, to be followed by the Greek Dark Ages , a recordless transitional period leading to Archaic Greece where significant shifts occurred from palace-centralized to decentralized forms of socio-economic organization (including the extensive use of iron ). Various theories have been proposed for the end of this civilization, among them

3366-544: The ethnonym Danaoi ( Greek : Δαναοί ), the name of the mythical dynasty that ruled in the region of Argos, also used as an ethnonym for the Greek people by Homer. In the official records of another Bronze Age empire, that of the Hittites in Anatolia , various references from c.  1400 BC to 1220 BC mention a country named Ahhiyawa . Recent scholarship, based on textual evidence, new interpretations of

3468-519: The ethnonyms Achaeans , Danaans , and Argives to refer to the besiegers, and these names appear to have passed down from the time they were in use to the time when Homer applied them as collective terms in his Iliad . There is an isolated reference to a-ka-wi-ja-de in the Linear B records in Knossos , Crete dated to c.  1400 BC , which presumably refers to a Mycenaean (Achaean) state on

3570-470: The sculptures that feature prominently on the bridge. Four gilt-bronze statues of Fames watch over the bridge, supported on massive 17 metres (56 ft) masonry socles , that provide stabilizing counterweight for the arch, without interfering with monumental views. The socles are crowned by Fames restraining Pegasus . The nymph reliefs are at the centres of the arches over the Seine, memorials to

3672-565: The 15th century, even featured a span length of 72 m (236 ft), not matched until 1796. Constructions such as the acclaimed Florentine segmental arch bridge Ponte Vecchio (1345) combined sound engineering (span-to-rise ratio of over 5.3 to 1) with aesthetical appeal. The three elegant arches of the Renaissance Ponte Santa Trinita (1569) constitute the oldest elliptic arch bridge worldwide. Such low rising structures required massive abutments , which at

3774-652: The Ahhiyawans. These Ekwesh were mentioned as a group of the Sea People . Scholars have proposed different theories on the origins of the Mycenaeans. According to one theory, Mycenaean civilization reflected the exogenous imposition of archaic Indo-Europeans from the Eurasian steppe onto the pre-Mycenaean local population. An issue with this theory, however, is the very tenuous material and cultural relationship between Aegean and northern steppe populations during

3876-621: The Bronze Age. Another theory proposes that Mycenaean culture in Greece dates back to circa 3000 BC with Indo-European migrants entering a mainly-depopulated area; other hypotheses argue for a date as early as the seventh millennium BC (with the spread of agriculture ) and as late as 1600 BC (with the spread of chariot technology ). In a 2017 genetic study conducted by Lazaridis et al., "the Minoans and Mycenaeans were genetically similar, [but]

3978-719: The Franco-Russian Alliance. The Nymphs of the Seine has a relief of the arms of Paris, and faces the Nymphs of the Neva with the arms of Imperial Russia . They are both executed in hammered copper over forms by Georges Récipon . In the same political spirit, the Trinity Bridge in Saint Petersburg was conceived as a memorial to the Franco-Russian Alliance. It was designed by Gustave Eiffel , and

4080-547: The Greek mainland. Egyptian records mention a T(D)-n-j or Danaya ( Tanaju ) land for the first time c.  1437 BC , during the reign of Pharaoh Thutmoses III (r. 1479–1425 BC). This land is geographically defined in an inscription from the reign of Amenhotep III (r. c.  1390 –1352 BC), where a number of Danaya cities are mentioned, which cover the largest part of southern mainland Greece. Among them, cities such as Mycenae, Nauplion, and Thebes have been identified with certainty. Danaya has been equated with

4182-464: The Greek name for Greece . This period is divided into three subperiods: The Early Helladic (EH) period ( c.  3200 –2000 BC) was a time of prosperity with the use of metals and a growth in technology, economy and social organization. The Middle Helladic (MH) period ( c.  2000 –1700/1675 BC ) faced a slower pace of development, as well as the evolution of megaron -type dwellings and cist grave burials. The last phase of Middle Helladic,

4284-520: The Greek peninsula after the end of this cultural period. Lastly, the decipherment marked the advent of an Indo-European language in the Aegean region in contrast to unrelated prior languages spoken in adjoining areas. Various collective terms for the inhabitants of Mycenaean Greece were used by Homer in his 8th-century BC epic the Iliad in reference to the Trojan War . Homer interchangeably used

4386-618: The Hittite inscriptions, and recent surveys of archaeological evidence about Mycenaean–Anatolian contacts during this period, concludes that the term Ahhiyawa must have been used in reference to the Mycenaean world (land of the Achaeans), or at least to a part of it. This term may have also had broader connotations in some texts, possibly referring to all regions settled by Mycenaeans or regions under direct Mycenaean political control. Another similar ethnonym, Ekwesh , in twelfth century BC Egyptian inscriptions has been commonly identified with

4488-625: The Middle East, based on the considerable greater quantities of Mycenaean goods found there. On the other hand, trade with the Hittite lands in central Anatolia appears to have been limited. Trade with Troy is also well attested, while Mycenaean trade routes expanded further to the Bosphorus and the shores of the Black Sea . Mycenaean swords have been found as far away as Georgia in

4590-552: The Middle Helladic III ( c.  1750 –1675 BC), along with the Late Helladic (LH) period ( c.  1700 /1675–1050 BC) roughly coincide with Mycenaean Greece. The Late Helladic period is further divided into LHI and LHII, both of which coincide with the middle phase of Mycenaean Greece ( c.  1700 /1675–1420 BC), and LHIII ( c.  1420 –1050 BC), the period of expansion, and decline of

4692-558: The Mycenaean Linear B script, a writing system adapted for the use of the ( Indo-European ) Greek language of the Late Bronze Age , demonstrated the continuity of Greek speech from the second millennium BC into the eighth century BC when a new Phoenician-derived alphabetic script emerged. Moreover, it revealed that the bearers of Mycenaean culture were ethnically connected with the populations that resided in

4794-495: The Mycenaean acropolis. It appears that after this first wave of destruction a short-lived revival of Mycenaean culture followed. Mycenaean Greece continues to be mentioned in international affairs, particularly in Hittite records. In c.  1220 BC , the king of Ahhiyawa is again reported to have been involved in an anti-Hittite uprising in western Anatolia. Another contemporary Hittite account reports that Ahhiyawan ships should avoid Assyrian -controlled harbors, as part of

4896-683: The Mycenaean civilization. The transition period from the Bronze Age to the Iron Age in Greece is known as Sub-Mycenaean ( c.  1050 –1000 BC). Based on recent research, Alex Knodell (2021) considers the beginning of Mycenaean occupation in Peloponnese in Middle Helladic III ( c.  1750 –1675 BC), and divides the whole Mycenaean time into three cultural periods: Early Mycenaean ( c.  1750 –1400 BC), Palatial Bronze Age ( c.  1400 –1200 BC), and Postpalatial Bronze Age ( c.  1200 –1050 BC). The decipherment of

4998-471: The Mycenaean palatial states were newcomers or populations that already resided in Mycenaean Greece. Recent archaeological findings tend to favor the latter scenario. Additional theories, concerning natural factors , such as climate change, droughts, or earthquakes have also been proposed. Another theory considers the decline of the Mycenaean civilization as a manifestation of a common pattern for

5100-478: The Mycenaeans differed from Minoans in deriving additional ancestry from an ultimate source related to the hunter–gatherers of eastern Europe and Siberia, introduced via a proximal source related to the inhabitants of either the Eurasian steppe or Armenia." However, Lazaridis et al. admit that their research "does not settle th[e] debate" on Mycenaean origins. Historian Bernard Sergent notes that archaeology alone

5202-592: The Near East, Apulia in Italy and Spain . From that time period ( c.  1400 BC ), the palace of Knossos has yielded the earliest records of the Greek Linear B script, based on the previous Linear A of the Minoans. The use of the new script spread in mainland Greece and offers valuable insight into the administrative network of the palatial centers. However, the unearthed records are too fragmentary for

5304-436: The abutments of an arch bridge. The deck is suspended from the arch. The arch is in compression, in contrast to a suspension bridge where the catenary is in tension. A tied-arch bridge can also be a through arch bridge. An arch bridge with hinges incorporated to allow movement between structural elements. A single-hinged bridge has a hinge at the crown of the arch , a two-hinged bridge has hinges at both springing points and

5406-593: The acropolis of Mycenae, in particular the Grave Circles A and B , signified the elevation of a native Greek-speaking royal dynasty whose economic power depended on long-distance sea trade. During this period, the Mycenaean centers witnessed increased contact with the outside world, especially with the Cyclades and the Minoan centers on the island of Crete . Mycenaean presence appears to be also depicted in

5508-689: The activity of the Sea Peoples in the Eastern Mediterranean. They caused widespread destruction in Anatolia and the Levant and were finally defeated by Pharaoh Ramesses III in c. 1175 BC. One of the ethnic groups that comprised these people were the Eqwesh , a name that appears to be linked with the Ahhiyawa of the Hittite inscriptions. Alternative scenarios propose that the fall of Mycenaean Greece

5610-416: The arch and the deck is known as the spandrel . If the spandrel is solid, usually the case in a masonry or stone arch bridge, the bridge is called a closed-spandrel deck arch bridge . If the deck is supported by a number of vertical columns rising from the arch, the bridge is known as an open-spandrel deck arch bridge . The Alexander Hamilton Bridge is an example of an open-spandrel arch bridge. Finally, if

5712-400: The arch is built in two halves which are then leaned against each other. Many modern bridges, made of steel or reinforced concrete, often bear some of their load by tension within their structure. This reduces or eliminates the horizontal thrust against the abutments and allows their construction on weaker ground. Structurally and analytically they are not true arches but rather a beam with

5814-422: The arch supports the deck only at the top of the arch, the bridge is called a cathedral arch bridge . This type of bridge has an arch whose base is at or below the deck, but whose top rises above it, so the deck passes through the arch. The central part of the deck is supported by the arch via suspension cables or tie bars, as with a tied-arch bridge . The ends of the bridge may be supported from below, as with

5916-548: The architects Joseph Cassien-Bernard  [ fr ] and Gaston Cousin , was constrained by the need to keep the bridge from obscuring the view of the Champs-Élysées or the Invalides . The bridge was built by the engineers Jean Résal and Amédée Alby  [ fr ] . It was inaugurated in 1900 for the Exposition Universelle ( universal exhibition ) World's Fair, as were the nearby Grand Palais and Petit Palais . Numerous sculptors provided

6018-416: The coast of southern Anatolia, displays the established trade routes that supplied the Mycenaeans with all the raw materials and items that the economy of Mycenaean Greece needed, such as copper and tin for the production of bronze products. A chief export of the Mycenaeans was olive oil , which was a multi-purpose product. Cyprus appears to be the principal intermediary station between Mycenaean Greece and

6120-489: The commune. A council of elders was chaired, the ke-ro-si-ja (cf. γερουσία, gerousía ). The basileus , who in later Greek society was the name of the king, refers to communal officials. In general, Mycenaean society appears to have been divided into two groups of free men: the king's entourage, who conducted administrative duties at the palace, and the people, da-mo . These last were watched over by royal agents and were obliged to perform duties for and pay taxes to

6222-691: The decline of many ancient civilizations: the Minoan, the Harappan and the Western Roman Empire; the reason for the decline is migration due to overpopulation. The period following the end of Mycenaean Greece, c. 1100–800 BC, is generally termed the " Greek Dark Ages ". Mycenaean palatial states, or centrally organized palace-operating polities, are recorded in ancient Greek literature and mythology (e.g., Iliad , Catalogue of Ships ) and confirmed by discoveries made by modern archaeologists such as Heinrich Schliemann . Each Mycenaean kingdom

This type is still used in canal viaducts and roadways as it has a pleasing shape, particularly when spanning water, as the reflections of the arches form a visual impression of circles or ellipses. This type of bridge comprises an arch where the deck is completely above the arch. The area between

6426-664: The dominant center was probably located in Thebes or in Mycenae, with the latter state being the most probable center of power. The Neolithic agrarian village (6000 BC) constituted the foundation of Bronze Age political culture in Greece. The vast majority of the preserved Linear B records deal with administrative issues and give the impression that Mycenaean palatial administration was highly systematized, featuring thoroughly consistent language, terminology, tax calculations, and distribution logistics. Considering this sense of uniformity,

6528-482: The dominant power of the region, marking the beginning of the Mycenaean 'Koine' era (from Greek : Κοινή , common), a highly uniform culture that spread in mainland Greece and the Aegean. From the early 14th century BC, Mycenaean trade began to take advantage of the new commercial opportunities in the Mediterranean after the Minoan collapse. The trade routes were expanded further, reaching Cyprus , Amman in

6630-563: The drainage system of the Kopais basin in Boeotia, the building of a large dam outside Tiryns, and the drainage of the swamp in the Nemea valley. Also noticeable is the construction of harbors, such as the harbor of Pylos, that were capable of accommodating large Bronze Age era vessels like the one found at Uluburun . The Mycenaean economy also featured large-scale manufacturing as testified by

6732-791: The eastern Black Sea coast. Commercial interaction was also intense with the Italian peninsula and the western Mediterranean. Mycenaean products, especially pottery, were exported to southern Italy , Sicily and the Aeolian Islands . Mycenaean products also penetrated further into Sardinia , as well as southern Spain . Sporadic objects of Mycenaean manufacture were found in various distant locations, like in Central Europe, such as in Bavaria , Germany , where an amber object inscribed with Linear B symbols has been unearthed. Mycenaean bronze double axes and other objects dating from

6834-503: The eccentric Puente del Diablo (1282). The 14th century in particular saw bridge building reaching new heights. Span lengths of 40 m (130 ft), previously unheard of in the history of masonry arch construction, were now reached in places as diverse as Spain ( Puente de San Martín ), Italy ( Castelvecchio Bridge ) and France ( Devil's bridge and Pont Grand ) and with arch types as different as semi-circular, pointed and segmental arches. The bridge at Trezzo sull'Adda , destroyed in

6936-409: The end of Mycenae as a major power. The site was then reoccupied, but on a smaller scale. A recent study suggests that neither of the palaces at Tiryns or Midea were destroyed by an earthquake, and further studies have shown that upwards of fifty arrowheads were found scattered in the destruction debris at Midea perhaps indicating that the destruction was caused by an assault. The palace of Pylos , in

7038-423: The existence of new decentralized coastal and maritime networks there. It is attested by the cemetery of Perati that lasted a century and showed imports from Cyclades , Dodecanese , Crete, Cyprus, Egypt and Syria, as well as by the Late Helladic IIIC ( c.  1210 –1040 BC) cemetery of Drivlia at Porto Rafti ; located 2 km west of Perati. This indicates that Attica participated in long-distance trade, and

7140-435: The extent of workshop complexes that have been discovered, the largest known to date being the recent ceramic and hydraulic installations found in Euonymeia , next to Athens, that produced tableware, textiles, sails, and ropes for export and shipbuilding . The most famous project of the Mycenaean era was the network of roads in the Peloponnese . This appears to have facilitated the speedy deployment of troops—for example,

In June 2017, with Paris competing against Los Angeles to host the 2024 Summer Olympics (the latter would went on to host the 2028 edition ) , Paris turned some of its world-famous landmarks over to sports and installed diving boards on the Alexandre III bridge that spanned the Seine. The swimming leg of the triathlon and marathon swimming events

7344-547: The first written records of the Greek language , and their religion already included several deities that can also be found in the Olympic pantheon . Mycenaean Greece was dominated by a warrior elite society and consisted of a network of palace -centered states that developed rigid hierarchical, political, social, and economic systems . At the head of this society was the king, known as a wanax . Mycenaean Greece perished with

7446-407: The fortifications in various sites. In some cases, arrangements were also made for the creation of subterranean passages which led to underground cisterns. Tiryns, Midea and Athens expanded their defences with new cyclopean-style walls. The extension program in Mycenae almost doubled the fortified area of the citadel. To this phase of extension belongs the impressive Lion Gate , the main entrance into

7548-502: The head of this society was the king, known as wanax (Linear B: wa-na-ka) in Mycenaean Greek . All powers were vested in him, as the main landlord and spiritual and military leader. At the same time he was an entrepreneur and trader and was aided by a network of high officials. The presence of Ahhiyawa in western Anatolia is mentioned in various Hittite accounts from c.  1400 to c.  1220 BC . Ahhiyawa

7650-573: The later palaces. In a number of sites, defensive walls were also erected. Meanwhile, new types of burials and more imposing ones have been unearthed, which display a great variety of luxurious objects. Among the various burial types, the shaft grave became the most common form of elite burial, a feature that gave the name to the early period of Mycenaean Greece. Among the Mycenaean elite, deceased men were usually laid to rest in gold masks and funerary armor, and women in gold crowns and clothes gleaming with gold ornaments. The royal shaft graves next to

7752-457: The latter being the northernmost Mycenaean center. Knossos in Crete also became a Mycenaean center, where the former Minoan complex underwent a number of adjustments, including the addition of a throne room . These centers were based on a rigid network of bureaucracy where administrative competencies were classified into various sections and offices according to specialization of work and trades. At

7854-468: The military activities of an Ahhiyawan warlord, Attarsiya , possibly related to the mythic character of Atreus . Attarsiya attacked Hittite vassals in western Anatolia including Madduwatta . Later, in c. 1315 BC, an anti-Hittite rebellion headed by Arzawa , a Hittite vassal state, received support from Ahhiyawa. Meanwhile, Ahhiyawa appears to be in control of a number of islands in the Aegean, an impression also supported by archaeological evidence. During

7956-450: The palace, but the production of ceramics was only indirectly monitored. Regional transactions between the palaces are also recorded on a few occasions. The palatial centers organized their workforce and resources for the construction of large scale projects in the fields of agriculture and industry. The magnitude of some projects indicates that this was the result of combined efforts from multiple palatial centers. Most notable of them are

8058-464: The palace. Among those who could be found in the palace were well-to-do high officials, who probably lived in the vast residences found in proximity to Mycenaean palaces, but also others, tied by their work to the palace and not necessarily better off than the members of the da-mo , such as craftsmen, farmers, and perhaps merchants. Occupying a lower rung of the social ladder were the slaves, do-e-ro , ( cf. δοῦλος , doúlos ). These are recorded in

8160-507: The rations given to the dependent personnel. The Mycenaean palaces maintained extensive control of the nondomestic areas of production through careful control and acquisition and distribution in the palace industries, and the tallying of produced goods. For instance, the Knossos tablets record c. 80,000–100,000 sheep grazing in central Crete , and the quantity of the expected wool from these sheep and their offspring, as well as how this wool

8262-446: The reconstruction of the political landscape in Mycenaean Greece and they do not support nor deny the existence of a larger Mycenaean state. On the other hand, contemporary Hittite and Egyptian records suggest the presence of a single state under a "Great King". Alternatively, based on archaeological data, some sort of confederation among a number of palatial states appears to be possible. If some kind of united political entity existed,

8364-436: The region of Wilusa , and later invaded the island of Lesbos , which then passed into Ahhiyawan control. Scholars have speculated that the mythic tradition of the Trojan War could have a historical basis in the political turmoil of this era. As a result of this instability, the Hittite king initiated correspondence in order to convince his Ahhiyawan counterpart to restore peace in the region. The Hittite record mentions

8466-420: The reign of the Hittite king Hattusili III (c. 1267–1237 BC), the king of Ahhiyawa is recognized as a "Great King" and of equal status with the other contemporary great Bronze Age rulers: the kings of Egypt , Babylonia and Assyria . At that time, another anti-Hittite movement, led by Piyama-Radu , broke out and was supported by the king of Ahhiyawa. Piyama-Radu caused major unrest which may have extended to

8568-723: The remnants of a Mycenaean road, along with what appears to have been a Mycenaean defensive wall on the Isthmus of Corinth . The Mycenaean era saw the zenith of infrastructure engineering in Greece, and this appears not to have been limited to the Argive plain. Trade over vast areas of the Mediterranean was essential for the economy of Mycenaean Greece. The Mycenaean palaces imported raw materials, such as metals, ivory and glass, and exported processed commodities and objects made from these materials, in addition to local products: oil, perfume, wine, wool and pottery. International trade of that time

8670-455: The shape of an arch. See truss arch bridge for more on this type. A modern evolution of the arch bridge is the long-span through arch bridge . This has been made possible by the use of light materials that are strong in tension such as steel and prestressed concrete. "The Romans were the first builders in Europe, perhaps the first in the world, fully to appreciate the advantages of the arch,

8772-469: The southwestern Peloponnese, was destroyed in c. 1180 BC. The Linear B archives found there, preserved by the heat of the fire that destroyed the palace, mention hasty defence preparations due to an imminent attack without giving any detail about the attacking force. As a result of this turmoil, specific regions in mainland Greece witnessed a dramatic population decrease, especially Boeotia, Argolis and Messenia . Mycenaean refugees migrated to Cyprus and

8874-471: The state of nearby Orchomenos. Moreover, the palace of Mycenae appeared to have ruled over a territory two to three times the size of the other palatial states in Bronze Age Greece. Its territory would have also included adjacent centers, including Tiryns and Nauplion , which could plausibly be ruled by a member of Mycenae's ruling dynasty. The unearthed Linear B texts are too fragmentary for

8976-475: The texts as working either for the palace or for specific deities. The Mycenaean economy, given its pre-monetary nature, was a palace economy , focusing on the redistribution of goods, commodities and labor by a central administration. The preserved Linear B records in Pylos and Knossos indicate that the palaces were closely monitoring a variety of industries and commodities, the organization of land management and

9078-517: The use of a new dialect of Greek, the Doric one. It appears that the Dorians moved southward gradually over a number of years and devastated the territory, until they managed to establish themselves in the Mycenaean centers. A new type of ceramic also appeared, called "Barbarian Ware" because it was attributed to invaders from the north. On the other hand, the collapse of Mycenaean Greece coincides with

9180-676: The vault and the dome." Mycenaean Greece Mycenaean Greece (or the Mycenaean civilization ) was the last phase of the Bronze Age in ancient Greece , spanning the period from approximately 1750 to 1050 BC. It represents the first advanced and distinctively Greek civilization in mainland Greece with its palatial states, urban organization, works of art, and writing system. The Mycenaeans were mainland Greek peoples who were likely stimulated by their contact with insular Minoan Crete and other Mediterranean cultures to develop

9282-402: Was Jean-Rodolphe Perronet , who used much narrower piers, revised calculation methods and exceptionally low span-to-rise ratios. Different materials, such as cast iron , steel and concrete have been increasingly used in the construction of arch bridges. Stone, brick and other such materials are strong in compression and somewhat so in shear , but cannot resist much force in tension . As

9384-411: Was a result of internal disturbances which led to internecine warfare among the Mycenaean states or civil unrest in a number of states, as a result of the strict hierarchical social system and the ideology of the wanax. In general, due to the obscure archaeological picture in 12th–11th century BC Greece, there is a continuing controversy among scholars over whether the impoverished societies that succeeded

9486-522: Was abandoned, while the Boeotian fortifications of Gla displays evidence for a targeted destruction as only the four gates and the monumental building, called the Melathron, were burned before the site was abandoned. In the Peloponnese, a number of buildings surrounding the citadel of Mycenae were attacked and burned. These incidents appear to have prompted the massive strengthening and expansion of

9588-465: Was allocated. The archives of Pylos display a specialized workforce, where each worker belonged to a precise category and was assigned to a specific task in the stages of production, notably in textiles. Nevertheless, palatial control over resources appears to have been highly selective in spatial terms and in terms of how different industries were managed. Thus, sectors like the production of perfumed oil and bronze materials were directly monitored from

9690-548: Was also incorporated in a mainland-looking network. The site of Mycenae experienced a gradual loss of political and economic status, while Tiryns , also in the Argolid region, expanded its settlement and became the largest local center during the post-palatial period, in Late Helladic IIIC, c. 1200–1050 BC. The reasons for the end of the Mycenaean culture have been hotly debated among scholars. At present, there

9792-648: Was built between 1896 and 1900. It is named after Tsar Alexander III of Russia , who had concluded the Franco-Russian Alliance in 1892. His son Nicholas II laid the foundation stone in October 1896. The style of the bridge reflects that of the Grand Palais , to which it leads on the right bank. The construction of the bridge is a marvel of 19th century engineering, consisting of a 6 metres (20 ft) high single span steel arch. The design, by

9894-418: Was governed from the palace, which exercised control over most, if not all, industries within its realm. The palatial territory was divided into several sub-regions, each headed by its provincial center. Each province was further divided in smaller districts, the damoi . A number of palaces and fortifications appear to be part of a wider kingdom. For instance, Gla , located in the region of Boeotia, belonged to

9996-521: Was held here. [REDACTED] [REDACTED] [REDACTED] 48°51′49″N 2°18′49″E  /  48.86361°N 2.31361°E  / 48.86361; 2.31361 Deck arch bridge Possibly the oldest existing arch bridge is the Mycenaean Arkadiko Bridge in Greece from about 1300 BC. The stone corbel arch bridge is still used by the local populace. The well-preserved Hellenistic Eleutherna Bridge has

10098-482: Was not only conducted by palatial emissaries but also by independent merchants. Based on archaeological findings in the Middle East, in particular physical artifacts, textual references, inscriptions and wall paintings, it appears that Mycenaean Greeks achieved strong commercial and cultural interaction with most of the Bronze Age people living in this region: Canaanites , Kassites , Mitanni , Assyrians , and Egyptians . The 14th century BC Uluburun shipwreck , off

10200-421: Was the lāwāgetas ("the leader of the people"), whose role appears mainly religious. His activities possibly overlap with the wanax and is usually seen as the second-in-command. Both wanax and lāwāgetas were at the head of a military aristocracy known as the eqeta ("companions" or "followers"). The land possessed by the wanax is usually the témenos (te-me-no). There is also at least one instance of

10302-859: Was the most important base for Mycenaean activity in Asia Minor. Mycenaean presence also reached the adjacent sites of Iasus and Ephesus . Meanwhile, imposing palaces were built in the main Mycenaean centers of the mainland. The earliest palace structures were megaron-type buildings, such as the Menelaion in Sparta , Lakonia . Palaces proper are datable from c.  1400 BC , when Cyclopean fortifications were erected at Mycenae and nearby Tiryns . Additional palaces were built in Midea and Pylos in Peloponnese , Athens , Eleusis , Thebes and Orchomenos in Central Greece and Iolcos , in Thessaly ,

10404-713: Was to be the longest arch bridge for a thousand years both in terms of overall and individual span length, while the longest extant Roman bridge is the 790 m-long (2,590 ft) long Puente Romano at Mérida . The late Roman Karamagara Bridge in Cappadocia may represent the earliest surviving bridge featuring a pointed arch. In medieval Europe, bridge builders improved on the Roman structures by using narrower piers , thinner arch barrels and higher span-to-rise ratios on bridges. Gothic pointed arches were also introduced, reducing lateral thrust, and spans increased as with
