As with pottery, the Greeks did not produce sculpture merely for artistic display. Statues were commissioned either by aristocratic individuals or by the state, and used for public memorials, as offerings to temples, oracles and sanctuaries (as is frequently shown by inscriptions on the statues), or as markers for graves. Statues in the Archaic period were not all intended to represent specific individuals. They were depictions of an ideal—beauty, piety, honor or sacrifice. These were always depictions of young men, ranging in age from adolescence to early maturity, even when placed on the graves of (presumably) elderly citizens. "Kouroi" were all stylistically similar. Graduations in the social stature of the person commissioning the statue were indicated by size rather than artistic innovations.
