Definition for Roman Classicism
From Biology Forums Dictionary
Roman classicism dates to the turn of the Common or Christian Era and the reign of Augustus Caesar. Although the Romans copied many Greek classical works and forms, in architecture they added one important element, which differentiates Roman classicism from Greek classicism: the Roman, or semicircular, round arch. The Roman classical style also employs attached columns. Prototypical examples of the style are the Colosseum of Rome and aqueducts such as at Pont du Gard (France) and Segovia (Spain).
