The Greeks had gone through three different stages of artistic development: The Geometric period consisting of geometric designs and figures painted on pottery, the Archaic period that introduced human marble statuary, and the Classical period, where artists further refined the human sculptures to define their beauty. The Greeks have been most notable for their stunning architecture and sculptures.

Roman: 
Roman art was heavily influenced by the Greeks, but it also had influence from Etruscan and Egyptian culture, as well as the many other Mediterranean cultures that surrounded the Empire. The most famous forms of Roman artwork were Roman busts (sculpture of just the head), sculpture, paintings, and mosaics. 

Both Greek and Roman art served as a foundation for further schools of art to build off their techniques and ideas. Their effects on art can be observed in the Renaissance, where Europeans revived the classics.
