The art of the ancient Greeks and Romans is called classical art. This name is used also to describe later periods in which artists looked for their inspiration to this ancient style. The Romans learned sculpture and painting largely from the Greeks and helped to transmit Greek art to later ages.
The Archaic period (ca. 800-500 BC) was the formative era of Greek art, while the Classical period (ca. 500-330 BC) was the culminating age. The history of large-scale sculpture in Europe essentially begins with ancient Greece; only a handful of large sculpted works were produced by earlier cultures.he four most renowned Greek sculptors all lived during the Classical age. One of these sculptors (Phidias) is remembered primarily for architectural sculpture, while the other three (Myron, Polyclitus, and Praxiteles) mainly produced statues.
