His body is a naked man's, entwined by a serpent (or two serpents, like a caduceus), with the snake's head often resting on the lion's head. The lion's mouth is often open. He is usually represented as having four wings, two keys (sometimes a single key), and a sceptre in his hand. Sometimes the figure is standing on a globe inscribed with a diagonal cross. On the figure from the Ostia Antica Mithraeum (left, CIMRM 312), the four wings carry the symbols of the four seasons, and a thunderbolt is engraved on his chest. At the base of the statue are the hammer and tongs of Vulcan and Mercury's cock and wand (caduceus). A rare variation of the same figure is also found with a human head and a lion's head emerging from its chest.
