CIMRM 321 - Grey marble tauroctony relief. Cortile of the Belvedere, Vatican, Italy.
A tauroctony relief, assembled from fragments, and embedded high up, in a wall in the Belvedere courtyard in the Vatican museums.
Comparing the Raddato picture with the CIMRM reference photo, the right-hand side (including Mithras) is the same; but the left hand fragment is not! I am unclear what has become of the left-hand fragment, or where the replacement came from.
