The traditional beginning of the Classical period is 480 bc. The flowering of the arts in a ‘Golden Age’ of Athens. ‘Classical’ has come to refer to this period above all. But the Classical period encompasses a much broader range, from experimentation in early Classical sculpture at the temple of Zeus at Olympia to the innovations of the sculptors of the 4th century bc, Praxiteles and Lysippus.

Representation of daily life is restricted to pottery and funerary art. - Oxford Encyclopedia of Art online
