Mausoleum of Galla Placidia, west apse

Following the traditional iconography, Peter carries keys and has a short, square beard while Paul carries a scroll and is balding from the front. Like the other saints pictured in the mausoleum, they wear short togas over ankle-length white tunics or albs with two vertical stripes.
