Roman Archietecture

The architecture of Ancient Rome at first adopted the external Greek architecture for their own purposes, which were so different from Greek buildings as to create a new architectural style. The two styles are often considered one body of classical architecture. However, by the late Republic, the architectural style developed its own highly distinctive style by introducing the previously little-used arches, vaults and domes. A crucial factor in this development, coined the Roman Architectural Revolution, was the invention of concrete. The Romans, similarly, were indebted to their Etruscan neighbors and forefathers who supplied them with a wealth of knowledge essential for future architectural solutions, such as hydraulics and in the construction of arches.

Tile covered concrete quickly supplanted marble 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 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 ably described by Vitruvius writing in the first century AD in his work De Architectura.

Common materials of Greek architecture were wood, used for supports and roof beams; plaster, used for sinks and bathtubs; unbaked brick, used for walls, especially for private homes; limestone and marble, used for columns, walls, and upper portions of temples and public buildings; terracotta, used for roof tiles and ornaments; and metals, especially bronze, used for decorative details. Architects of the Archaic and Classical periods used these building materials to construct five simple types of buildings: religious, civic, domestic, funerary, or recreational.
