The stone was given a rocky appearance and is concave at the back. On its front a very remarkable representation of Mithras's rockbirth. Cautes and Cautopates in Oriental dress assist Mithras at his rockbirth pulling him out by the arms. Mithras holds in his uplifted r.h. a knife and in his l.h. a torch. Above this scene a person in long hair and beard is reclining on the rock. The upper part of his body is naked. Beside him is a dagger (Saturnus). A Victoria flies towards him.
