84-403: "Tarikhaneh" is derived from tari ("god") and khaneh ("home"), thus meaning "god's home". The chronology of the building's construction is not well-documented. Based on its very close similarities with earlier Sassanian architecture, it is likely from the first centuries of Islamic rule, possibly in the 8th century. Some scholars have suggested that is overall form and style corresponds more to

168-404: A finite element algorithm to calculate gravity induced stresses from the self weight of an arched system. In fact, for structural engineers, analysis of the barrel vault has become a benchmark test of a structural engineering computer model "because of the complex membrane and inextensional bending states of stress" involved. In terms of comparison to other vaulting techniques, the barrel vault

252-469: A span of only two metres. In these early instances, the barrel vault was chiefly used for underground structures such as drains and sewers , though several buildings of the great Late Egyptian mortuary palace - temple of Ramesseum were also vaulted in this way. Recent archaeological evidence discovered at the Morgantina site (in the province of Enna ) shows that the aboveground barrel vault

336-444: A tunnel vault , wagon vault or wagonhead vault , is an architectural element formed by the extrusion of a single curve (or pair of curves, in the case of a pointed barrel vault) along a given distance. The curves are typically circular in shape, lending a semi-cylindrical appearance to the total design. The barrel vault is the simplest form of a vault : effectively a series of arches placed side by side (i.e., one after another). It

420-523: A Temple of Jupiter at the north end, and would also contain other temples, as well as the basilica ; a public weights and measures table, so customers at the market could ensure they were not being sold short measures; and would often have the baths nearby. A horreum was a type of public warehouse used during the ancient Roman period. Although the Latin term is often used to refer to granaries , Roman horrea were used to store many other types of consumables;

504-442: A degree of painted colourful murals on the walls. Examples have been found of jungle scenes with wild animals and exotic plants. Imitation windows ( trompe-l'œil ) were sometimes painted to make the rooms seem less confined. Ancient Rome had elaborate and luxurious houses owned by the elite. The average house, or in cities apartment, of a commoner or plebeius did not contain many luxuries. The domus , or single-family residence,

588-557: A great deal of weight. The first use of concrete by the Romans was in the town of Cosa sometime after 273 BC. Ancient Roman concrete was a mixture of lime mortar , aggregate , pozzolana , water, and stones , and was stronger than previously used concretes. The ancient builders placed these ingredients in wooden frames where they hardened and bonded to a facing of stones or (more frequently) bricks. The aggregates used were often much larger than in modern concrete, amounting to rubble. When

672-527: A huge barrel vault spans the 27 m (89 ft)-wide nave. With a barrel vault design the vectors of pressure result in a downward force on the crown while the lower portions of the arches realise a lateral force pushing outwards. As an outcome this form of design is subject to failure unless the sides are anchored or buttressed to very heavy building elements or substantial earthwork sidings. For example, at Muchalls Castle in Scotland , adjacent walls to

756-438: A load-bearing wall. In smaller-scale architecture, concrete's strength freed the floor plan from rectangular cells to a more free-flowing environment. Factors such as wealth and high population densities in cities forced the ancient Romans to discover new architectural solutions of their own. The use of vaults and arches , together with a sound knowledge of building materials, enabled them to achieve unprecedented successes in

840-516: A load-bearing wall. In smaller-scale architecture, concrete's strength freed the floor plan from rectangular cells to a more free-flowing environment. Most of these developments are described by Vitruvius , writing in the first century BC in his work De architectura . Although concrete had been used on a minor scale in Mesopotamia, Roman architects perfected Roman concrete and used it in buildings where it could stand on its own and support

924-559: A marketplace, a forum was a gathering place of great social significance, and often the scene of diverse activities, including political discussions and debates, rendezvous, meetings, etc. The best known example is the Roman Forum , the earliest of several in Rome. In new Roman towns the forum was usually located at, or just off, the intersection of the main north–south and east–west streets (the cardo and decumanus ). All forums would have

1008-490: A median strip running along the length of about two thirds the track, joined at one end with a semicircular section and at the other end with an undivided section of track closed (in most cases) by a distinctive starting gate known as the carceres , thereby creating a circuit for the races. During the years of the Republic, Augustus claimed he "found the city in brick and left it in marble". While chances are high that this

1092-541: A return to stone barrel vaults was seen for the first great cathedrals; their interiors were fairly dark, due to thick, heavy walls needed to support the vault. One of the largest and most famous churches enclosed from above by a vast barrel vault was the church of Cluny Abbey , built between the 11th and 12th centuries. In 13th and 14th centuries, with the advance of the new Gothic style, barrel vaulting became almost extinct in constructions of great Gothic cathedrals; groin vaults reinforced by stone ribs were mostly used in

1176-562: A scraper made of wood or bone. Roman bath-houses were also provided for private villas , town houses and forts . They were normally supplied with water from an adjacent river or stream, or by aqueduct . The design of thermae is discussed by Vitruvius in De architectura . Roman temples were among the most important and richest buildings in Roman culture, though only a few survive in any sort of complete state. Their construction and maintenance

1260-412: A structure which survives to this day. A smaller lighthouse at Dover , England also exists as a ruin about half the height of the original. The light would have been provided by a fire at the top of the structure. All Roman cities had at least one thermae , a popular facility for public bathing, exercising and socializing. Exercise might include wrestling and weightlifting, as well as swimming. Bathing

1344-570: A vault is a tunnel vault found under the Sumerian ziggurat at Nippur in Babylonia , ascribed to about 4000 BC, which was built from fired bricks amalgamated with clay mortar . The earliest tunnel vaults in Egypt are found at Requagnah and Denderah , from around 3500 BC in the predynastic era. These were built with sun-dried brick in three rings over passages descending to tombs with

1428-533: A whole room (cella), a closet (armarium), or only a chest or strong box (arca, arcula, locus, loculus)." Multi-story apartment blocks called insulae catered to a range of residential needs. The cheapest rooms were at the top owing to the inability to escape in the event of a fire and the lack of piped water. Windows were mostly small, facing the street, with iron security bars. Insulae were often dangerous, unhealthy, and prone to fires because of overcrowding and haphazard cooking arrangements. There are examples in

1512-472: Is a form of barrel roof . As with all arch -based constructions, there is an outward thrust generated against the walls underneath a barrel vault. There are several mechanisms for absorbing this thrust. One is to make the walls exceedingly thick and strong – this is a primitive and sometimes unacceptable method. A more elegant method is to build two or more vaults parallel to each other; the forces of their outward thrusts will thus negate each other. This method

1596-558: Is arguably the Roman contribution most relevant to modern architecture. The amphitheatre was, with the triumphal arch and basilica , the only major new type of building developed by the Romans. Some of the most impressive secular buildings are the amphitheatres, over 200 being known and many of which are well preserved, such as that at Arles , as well as its progenitor, the Colosseum in Rome. They were used for gladiatorial contests, public displays, public meetings and bullfights ,

1680-564: Is constructed from Roman bricks 15" square by 1½" thick. There is often little obvious difference (particularly when only fragments survive) between Roman bricks used for walls on the one hand, and tiles used for roofing or flooring on the other, so archaeologists sometimes prefer to employ the generic term ceramic building material (or CBM). The Romans perfected brick-making during the first century of their empire and used it ubiquitously, in public and private construction alike. They took their brickmaking skills everywhere they went, introducing

1764-463: Is inherently a weaker design compared to the more complex groin vault . The barrel vault structure must rest on long walls creating less stable lateral stress, whereas the groin vault design can direct stresses almost purely vertically on the apexes. There are numerous contemporary examples of barrel vault design in Victorian and modern architecture , including: Beyond the classical use of

1848-414: Is not found especially close to Rome, and was only rarely used there before Augustus , who famously boasted that he had found Rome made of brick and left it made of marble, though this was mainly as a facing for brick or concrete. The Temple of Hercules Victor of the late 2nd century BC is the earliest surviving exception in Rome. From Augustus' reign the quarries at Carrara were extensively developed for

1932-588: Is observed in cellars , crypts , long hallways , cloisters and even great halls . Barrel vaulting was known and utilized by early civilizations, including ancient Egypt and Mesopotamia . However, it apparently was not a very popular or common method of construction within these civilizations. The Persians and the Romans were the first to make significant architectural use of them. The technique probably evolved out of necessity to roof buildings with masonry elements such as bricks or stone blocks in areas where timber and wood were scarce. The earliest known example of

2016-669: The Ancient Iran ( Elam ), Indian Indus Valley civilization and Ancient Egypt , and were used extensively in Roman architecture . They were also used to replace the Cloaca Maxima with a system of underground sewers. Other early barrel vault designs occur in northern Europe , Turkey , Morocco , and other regions. In medieval Europe, the barrel vault was an important element of stone construction in monasteries , castles , tower houses and other structures. This form of design

2100-840: The Aqueduct of Segovia , the Pont du Gard , and the eleven aqueducts of Rome . The same concepts produced numerous bridges, some of which are still in daily use, for example, the Puente Romano at Mérida in Spain, and the Pont Julien and the bridge at Vaison-la-Romaine , both in Provence, France. The dome permitted the construction of vaulted ceilings without crossbeams and made possible large covered public spaces such as public baths and basilicas , such as Hadrian's Pantheon ,

2184-525: The Baths of Diocletian and the Baths of Caracalla , all in Rome. The Romans first adopted the arch from the Etruscans and implemented it in their own building. The use of arches that spring directly from the tops of columns was a Roman development, seen from the 1st century AD, that was very widely adopted in medieval Western, Byzantine and Islamic architecture . The Romans were the first builders in

2268-465: The Pantheon in its current form and leaving his mark on the landscape of northern Britain with Hadrian's Wall . While borrowing much from the preceding Etruscan architecture, such as the use of hydraulics and the construction of arches, Roman prestige architecture remained firmly under the spell of ancient Greek architecture and the classical orders . This came initially from Magna Graecia ,

2352-558: The Roman Republic and to an even greater extent under the Empire , when the great majority of surviving buildings were constructed. It used new materials, particularly Roman concrete , and newer technologies such as the arch and the dome to make buildings that were typically strong and well engineered. Large numbers remain in some form across the former empire, sometimes complete and still in use today. Roman architecture covers

2436-530: The bathhouse , and civil engineering such as fortifications and bridges. In Europe the Italian Renaissance saw a conscious revival of correct classical styles, initially purely based on Roman examples. Vitruvius was respectfully reinterpreted by a series of architectural writers, and the Tuscan and Composite orders formalized for the first time, to give five rather than three orders. After

2520-475: The history of architecture to realize the potential of domes for the creation of large and well-defined interior spaces. Domes were introduced in a number of Roman building types such as temples , thermae , palaces , mausolea and later also churches. Half-domes also became a favored architectural element and were adopted as apses in Christian sacred architecture . Monumental domes began to appear in

2604-644: The hypocaust , mica glazing (examples in Ostia Antica ), and piped hot and cold water (examples in Pompeii and Ostia). Despite the technical developments of the Romans, which took their buildings far away from the basic Greek conception where columns were needed to support heavy beams and roofs, they were reluctant to abandon the classical orders in formal public buildings, even though these had become essentially decorative. However, they did not feel entirely restricted by Greek aesthetic concerns and treated

Along with vaults , they gradually replaced the traditional post and lintel construction which makes use of the column and architrave . The construction of domes was greatly facilitated by the invention of concrete , a process which has been termed the Roman architectural revolution . Their enormous dimensions remained unsurpassed until

Some were razed, and others converted into fortifications. A few continued as convenient open meeting places; in some of these, churches were sited. Architecturally, they are typically an example of the Roman use of the classical orders to decorate large concrete walls pierced at intervals, where

2940-405: The 9th century. The main plan consists of a square courtyard which is surrounded by arcades of barrel vaults supported by slightly pointed fired brick arches set on thick circular pillars, typical of Sassanid architecture . The pillars are 3.5 meters tall and almost 2 meters in diameter. The hypostyle prayer hall consists of several naves or aisles divided by arcades and covered by vaults, with

3024-507: The Empire made possible very large projects even in locations remote from the main centers, as did the use of slave labor, both skilled and unskilled. Especially under the empire, architecture often served a political function, demonstrating the power of the Roman state in general, and of specific individuals responsible for building. Roman architecture perhaps reached its peak in the reign of Hadrian , whose many achievements include rebuilding

3108-526: The Forum proved to be the most influential for years to come. According to Walter Dennison's The Roman Forum As Cicero Saw It , the author writes that "the diverting of public business to the larger and splendid Imperial fora erected in the vicinity resulted in leaving the general design of the Forum Romanum". Every city had at least one forum of varying size. In addition to its standard function as

The influence is evident in many ways; for example, in the introduction and use of the triclinium in Roman villas as a place and manner of dining. Roman builders employed Greeks in many capacities, especially in

3276-444: The Roman port town of Ostia , that date to the reign of Trajan , but they seem to have been found mainly in Rome and a few other places. Elsewhere writers report them as something remarkable, but Livy and Vitruvius refer to them in Rome. External walls were in opus reticulatum and interiors in opus incertum , which would then be plastered and sometimes painted. To lighten up the small dark rooms, some tenants able to afford

3360-580: The Romanesque medieval builders had to resort to techniques of small windows, large buttresses, or other forms of interior wall cross-bracing to achieve the desired lighting outcomes. In many of the monasteries, a natural solution was cloisters which could have high barrel-vaulted construction with an open courtyard to allow ample lighting. Since 1996 structural engineers have applied Newtonian mechanics to calculate numeric stress loads for ancient stonework barrel vaults. These analyses have typically used

3444-641: The Romans. The classical orders now became largely decorative rather than structural, except in colonnades . Stylistic developments included the Tuscan and Composite orders ; the first being a shortened, simplified variant on the Doric order and the Composite being a tall order with the floral decoration of the Corinthian and the scrolls of the Ionic . The period from roughly 40 BC to about 230 AD saw most of

3528-426: The ancient Romans was followed by a 600–700 year gap in major brick production. Concrete quickly supplanted brick as the primary building material, and more daring buildings soon followed, with great pillars supporting broad arches and domes rather than dense lines of columns suspending flat architraves . The freedom of concrete also inspired the colonnade screen, a row of purely decorative columns in front of

3612-451: The ancient and Classical predecessors, they demonstrate the pervasiveness of the barrel vault as an architectural concept in contemporary times. In the field of bone surgery the technique of a "barrel vault" shaped incision is not only a well-defined state-of-the-art surgical procedure, but the name barrel vault is given to this technique by orthopedic surgeons . The Wohlfahrt study cited documents results of this surgical procedure on

3696-402: The barrel vault in macro-architectural design (e.g. as a major structural roofing element), there are a variety of derivative applications clearly based on the original concept and shape of the barrel vault. These applications arise in the fields of surgery , skylight design, children's toys and microstructure design (such as bus shelters). While none of these applications rival the majesty of

3780-425: The barrel vaulted chambers are up to 4.6 m (15 ft) thick, adding the buttressing strength needed to secure the curved design. The inherent difficulty of adequately lighting barrel vaulted structures has been widely acknowledged. The intrinsic engineering issue is the need to avoid fenestration punctures in stonework barrel vaults. Such openings could compromise the integrity of the entire arch system. Thus

3864-676: The beginning, and later on various types of spectacular, ornate and complex medieval vaults were developed. However, with the coming of the Renaissance and the Baroque style, and revived interest in art and architecture of antiquity, barrel vaulting was re-introduced on a truly grandiose scale, and employed in the construction of many famous buildings and churches, such as Basilica di Sant'Andrea di Mantova by Leone Battista Alberti , San Giorgio Maggiore by Andrea Palladio , and perhaps most glorious of all, St. Peter's Basilica in Rome, where

3948-474: The capital, and other sources around the empire exploited, especially the prestigious Greek marbles like Parian . Travertine limestone was found much closer, around Tivoli , and was used from the end of the Republic; the Colosseum is mainly built of this stone, which has good load-bearing capacity, with a brick core. Other more or less local stones were used around the Empire. The Romans were fond of luxury imported coloured marbles with fancy veining, and

4032-438: The central nave being larger than the others. Standing together at a distance from the mosque are the remains of a square column of uncertain date, possibly part of the original construction period and a cylindrical minaret . The latter was built sometime in the years 1026 to 1028. It resembles the style of later Seljuk minarets. The minaret is 4.2 meters in diameter; its top has fallen, but originally it must have measured more

4116-399: The columns have nothing to support. Aesthetically, however, the formula is successful. The Roman basilica was a large public building where business or legal matters could be transacted. They were normally where the magistrates held court, and used for other official ceremonies, having many of the functions of the modern town hall . The first basilicas had no religious function. As early as

4200-533: The construction of imposing infrastructure for public use. Examples include the aqueducts of Rome , the Baths of Diocletian and the Baths of Caracalla , the basilicas and Colosseum . These were reproduced at a smaller scale in the most important towns and cities in the Empire. Some surviving structures are almost complete, such as the town walls of Lugo in Hispania Tarraconensis , now northern Spain. The administrative structure and wealth of

4284-492: The craft to the local populations. The Roman legions , which operated their own kilns , introduced bricks to many parts of the Empire; bricks are often stamped with the mark of the legion that supervised their production. The use of bricks in southern and western Germany, for example, can be traced to traditions already described by the Roman architect Vitruvius . In the British Isles , the introduction of Roman brick by

4368-472: The end of the 2nd century BC, with the first known public horreum being constructed by the ill-fated tribune Gaius Gracchus in 123 BC. The word came to be applied to any place designated for the preservation of goods; thus, it was often used to refer to cellars ( horrea subterranea ), but it could also be applied to a place where artworks were stored, or even to a library. Some public horrea functioned somewhat like banks, where valuables could be stored, but

4452-542: The excessive decoration and display of wealth that aristocrats' houses contained. Luxury in houses was not common, as the life of the average person did not consist of being in their houses, as they instead would go to public baths, and engage in other communal activities. Many lighthouses were built around the Mediterranean and the coasts of the empire, including the Tower of Hercules at A Coruña in northern Spain,

4536-783: The flamboyance of Baroque architecture , the Neoclassical architecture of the 18th century revived purer versions of classical style, and for the first time added direct influence from the Greek world. Numerous local classical styles developed, such as Palladian architecture , Georgian architecture and Regency architecture in the English-speaking world, Federal architecture in the United States, and later Stripped Classicism and PWA Moderne . Roman influences may be found around us today, in banks, government buildings, great houses, and even small houses, perhaps in

4620-791: The form of a porch with Doric columns and a pediment or in a fireplace or a mosaic shower floor derived from a Roman original, often from Pompeii or Herculaneum . The mighty pillars, domes and arches of Rome echo in the New World too, where in Washington, D.C. stand the Capitol building , the White House , the Lincoln Memorial , and other government buildings. All across the US the seats of regional government were normally built in

4704-518: The framework was removed, the new wall was very strong, with a rough surface of bricks or stones. This surface could be smoothed and faced with an attractive stucco or thin panels of marble or other coloured stones called a "revetment". Concrete construction proved to be more flexible and less costly than building solid stone buildings. The materials were readily available and not difficult to transport. The wooden frames could be used more than once, allowing builders to work quickly and efficiently. Concrete

4788-587: The giant Horrea Galbae in Rome were used not only to store grain but also olive oil , wine, foodstuffs, clothing and even marble . By the end of the Imperial period, the city of Rome had nearly 300 horrea to supply its demands. The biggest were enormous, even by modern standards; the Horrea Galbae contained 140 rooms on the ground floor alone, covering an area of some 225,000 square feet (20,900 square metres). The first horrea were built in Rome towards

4872-504: The grand traditions of Rome, with vast flights of stone steps sweeping up to towering pillared porticoes, with huge domes gilded or decorated inside with the same or similar themes that were popular in Rome. In Britain, a similar enthusiasm has seen the construction of thousands of neoclassical buildings over the last five centuries, both civic and domestic, and many of the grandest country houses and mansions are purely Classical in style, an obvious example being Buckingham Palace . Marble

4956-632: The great boom in construction in the early Empire. The Roman architectural revolution , also known as the "concrete revolution", was the widespread use in Roman architecture of the previously little-used architectural forms of the arch , vault , and dome . For the first time in history, their potential was fully exploited in the construction of a wide range of civil engineering structures, public buildings, and military facilities. These included amphitheatres , aqueducts , baths , bridges , circuses , dams , domes , harbours , temples , and theatres . According to Gottfried Semper , Roman architecture

5040-521: The greatest achievements, before the Crisis of the Third Century and later troubles reduced the wealth and organizing power of the central governments. The Romans produced massive public buildings and works of civil engineering, and were responsible for significant developments in housing and public hygiene, for example their public and private baths and latrines, under-floor heating in the form of

5124-506: The horreum as a structure made of brick, the walls of which were not less than three feet thick; it had no windows or openings for ventilation". Furthermore, the storehouses would also host oil and wine and also use large jars that could serve as cache's for large amounts of products. These storehouses were also used to keep large sums of money and were used much like personal storage units today are. "These horrea were divided and subdivided, so that one could hire only so much space as one wanted,

5208-405: The human tibia in 91 such operations. Roman architecture Ancient Roman architecture adopted the external language of classical ancient Greek architecture for the purposes of the ancient Romans , but was different from Greek buildings, becoming a new architectural style. The two styles are often considered one body of classical architecture . Roman architecture flourished in

5292-414: The interiors of the most important buildings were often faced with slabs of these, which have usually now been removed even where the building survives. Imports from Greece for this purpose began in the 2nd century BC. The Romans made fired clay bricks from about the beginning of the Empire, replacing earlier sun-dried mudbrick . Roman brick was almost invariably of a lesser height than modern brick, but

5376-670: The introduction of structural steel frames in the late 19th century (see List of the world's largest domes ). Roman architecture supplied the basic vocabulary of Pre-Romanesque and Romanesque architecture , and spread across Christian Europe well beyond the old frontiers of the empire, to Ireland and Scandinavia for example. In the East, Byzantine architecture developed new styles of churches, but most other buildings remained very close to Late Roman forms. The same can be said in turn of Islamic architecture , where Roman forms long continued, especially in private buildings such as houses and

5460-555: The magistrates sat, often on a slightly raised dais. The central aisle tended to be wide and was higher than the flanking aisles, so that light could penetrate through the clerestory windows. The oldest known basilica, the Basilica Porcia , was built in Rome in 184 BC by Cato the Elder during the time he was censor . Other early examples include the basilica at Pompeii (late 2nd century BC). After Christianity became

5544-430: The main entertainment sites of the time. Circuses were venues for chariot racing , horse races , and performances that commemorated important events of the Empire were performed there. For events that involved re-enactments of naval battles , the circus was flooded with water. The performance space of the Roman circus was normally, despite its name, an oblong rectangle of two linear sections of race track , separated by

5628-535: The middle of the first century BC, but most were built under Imperial rule, from the Augustan period (27 BC–14 AD) onwards. Imperial amphitheatres were built throughout the Roman Empire; the largest could accommodate 40,000–60,000 spectators, and the most elaborate featured multi-storeyed, arcaded façades and were elaborately decorated with marble , stucco and statuary. After the end of gladiatorial games in

5712-541: The most important class of horrea were those where foodstuffs such as grain and olive oil were stored and distributed by the state. The word itself is thought to have linguist roots tied to the word hordeum , which in Latin means barley. In the Johns Hopkins University Press , The Classical Weekly states that " Pliny the Elder does indeed make a distinction between the two words. He describes

5796-551: The official religion, the basilica shape was found appropriate for the first large public churches, with the attraction of avoiding reminiscences of the Greco-Roman temple form. The Roman circus was a large open-air venue used for public events in the ancient Roman Empire . The circuses were similar to the ancient Greek hippodromes , although circuses served varying purposes and differed in design and construction. Along with theatres and amphitheatres , circuses were one of

5880-400: The orders with considerable freedom. Innovation started in the 3rd or 2nd century BC with the development of Roman concrete as a readily available adjunct to, or substitute for, stone and brick. More daring buildings soon followed, with great pillars supporting broad arches and domes. The freedom of concrete also inspired the colonnade screen, a row of purely decorative columns in front of

5964-482: The period from the establishment of the Roman Republic in 509 BC to about the 4th century AD, after which it becomes reclassified as Late Antique or Byzantine architecture . Few substantial examples survive from before about 100 BC, and most of the major survivals are from the later empire, after about 100 AD. Roman architectural style continued to influence building in the former empire for many centuries, and

6048-575: The roof of the metal working furnace, the discovery was made by Vats in 1940 during excavation at Harappa . Ancient Romans most probably inherited their knowledge of barrel vaulting from Etruscans and the Near East. Persians and Romans were the first to use this building method extensively on large-scale projects and were probably the first to use scaffolding to aid them in construction of vaults spanning over widths greater than anything seen before. However, Roman builders gradually began to prefer

6132-752: The style used in Western Europe beginning about 1000 is called Romanesque architecture to reflect this dependence on basic Roman forms. The Romans only began to achieve significant originality in architecture around the beginning of the Imperial period , after they had combined aspects of their originally Etruscan architecture with others taken from Greece, including most elements of the style we now call classical architecture. They moved from trabeated construction mostly based on columns and lintels to one based on massive walls, punctuated by arches , and later domes , both of which greatly developed under

6216-510: The time of Augustus , a public basilica for transacting business had been part of any settlement that considered itself a city, used in the same way as the late medieval covered market houses of northern Europe, where the meeting room, for lack of urban space, was set above the arcades. Although their form was variable, basilicas often contained interior colonnades that divided the space, giving aisles or arcaded spaces on one or both sides, with an apse at one end (or less often at each end), where

6300-450: The tradition of which still survives in Spain and Portugal. Their typical shape, functions and name distinguish them from Roman theatres , which are more or less semicircular in shape; from the circuses (akin to hippodromes ) whose much longer circuits were designed mainly for horse or chariot racing events; and from the smaller stadia, which were primarily designed for athletics and footraces. The earliest Roman amphitheatres date from

6384-424: The use of groin vault ; though more complex to erect, this type of vault did not require heavy, thick walls for support (see below), and thus allowed for more spacious buildings with greater openings and much more light inside, such as thermae .
