in the 6th century bc, gorgoneia of a basic type of "lion mask" were found all over greek temples, especially in and around corinth. pedimental gorgoneia were common in sicily; probably the earliest one is in the temple of apollo in syracuse. around 500 bc, they stopped being used to decorate monumental buildings, but were still shown on parts of the roof tiles (antefix) of smaller buildings throughout the next century.
