The emperor was the chief state priest, and many statues show him in the act of prayer or sacrifice, with a fold of his toga pulled up to cover his head as a mark ofpiety. However, this highly idealized head may represent the Genius, or protective spirit, of the living emperor. Traditionally the protective spirit of every Roman household was worshiped at the family shrine. It was represented by a statuette with veiled head holding implements of sacrifice. Similar veneration of the GeniusAugusti, introduced by the paternalistic Augustus, was widespread at public shrines and altars.
