The most important scene besides the killing of the bull […] is the joint meal of Mithras and Helios/Sol, who lie together on the skin of the bull and, as was customary in antiquity, eat the brewed innards and drink wine with it. In order to appropriately emphasise the centrality of this cult meal, a special form of the main relief was developed, the central part of which could be rotated around its own axis at a certain moment of the ritual in order to vividly demonstrate to the cult participants the theological connection between the act of killing the bull and the first cult meal.
