On a restored base a standing Aion with lion's head. His body is entwined by six windings of a serpent, which lays its head on that of the god. He has two wings attached to his hips and originally there were two more attached to his shoulders. In the r.h. he holds a key one tooth of which is still visible; in the other hand a sceptre, which partly has been broken off. Beside his r. leg one perceives a winding thunderbolt, ending in a human head.
