Answer 2

The origins of Roman architecture can be traced to the Etruscans, who migrated from Asia Minor to Italy in the 12th cent. BC What little is known about their architecture has been ascertained from clay models and tomb interiors. Etruscan architecture is thought to have derived from prototypes found in the nearby Greek colonies in southern Italy established during the 8th and 7th cent. BC The Etruscans are thought to have used arches and vaults in their later architecture.

Following the establishment of the Roman Republic in the 5th cent. BC, Roman architects began to absorb and synthesize influences from both the Etruscans and the Greeks, adapting earlier building types to their specialized urban needs. A characteristic feature of Roman design was the combined use of arcuated and trabeated construction (employing arches and constructed with post and lintel).

Although at first tentatively employed in the spaces between the classical columns, the arch eventually came to be the chief structural element. Flanking columns, usually engaged and superimposed (partly embedded into a wall and laid over it), served merely as buttresses or for decoration.

The cut-stone construction of the Greeks was largely replaced after the invention of concrete in the 2d cent. BC This enabled architects to cover vast interior spaces with vaults of increasing complexity and without interior supports. These included the barrel vault, the cross or groined vault, and the dome and semidome. Vault buttresses, instead of forming exterior projections, became an integral part of the interior support system.

Although unfired brick was employed in all periods, under the empire baked bricks became popular as a facing for concrete walls. From early times stucco was used as a finish for important buildings. For the more luxurious finishing of exterior and interior walls, sheathings of alabaster, porphyry, or marble were used. Of the Republican period (c.500-27 BC), the great aqueducts outside the city of Rome are the most impressive remains.

Most important among the structures developed by the Romans themselves were basilicas, baths, amphitheaters, and triumphal arches. Unlike their Greek prototypes, Roman theaters were freestanding structures. The auditorium was semicircular, with movable seats at the orchestra level. Distinctly Roman innovation were the uniting of stage and auditorium as a single structure and the rich architectural embellishment of the stage itself.

For the oval amphitheaters such as the colosseum, there are no known Greek precedents. The monumental or triumphal arch was also a purely Roman invention. The basilica , probably a Roman development based on the Greek temple, provided a large and relatively open interior space. From its original use as a Roman law court, the basilica form was adapted by the Christians for their churches.
