This marble tauroctony relief, probably originating from Naples, depicts Mithras slaying the bull within a cave-like setting, accompanied by the usual animals and celestial busts.
The exhibition The Mystery of Mithras opens at the Mariemont Museum in Belgium, home of Franz Cumont, the father of studies on the solar god.
Franz Cumont bought this relief of Mithras as a bullkiller from a dealer who claimed to have found it in a vineyard near the church of Saint Pancrace, in Rome.
