In some depictions, the central tauroctony is framed by a series of subsidiary scenes to the left, top and right, illustrating events in the Mithras narrative; Mithras being born from the rock, the water miracle, the hunting and riding of the bull, meeting Sol who kneels to him, shaking hands with Sol and sharing a meal of bull-parts with him, and ascending to the heavens in a chariot. In some instances, as is the case in the stucco icon at Santa Prisca Mithraeum in Rome, the god is shown heroically nude. Some of these reliefs were constructed so that they could be turned on an axis. On the back side was another, more elaborate feasting scene. This indicates that the bull killing scene was used in the first part of the celebration, then the relief was turned, and the second scene was used in the second part of the celebration. Besides the main cult icon, a number of mithraea had several secondary tauroctonies, and some small portable versions, probably meant for private devotion, have also been found.
