Denarius depicting Mithras rock-birth of St. Albans

Finally one should mention the most interesting adaptation of a denarius of Augustus found at Verulamium (CIMRM 827) (Pl. XXII). The obverse has been entirely obliterated and replaced with the Greek legend MITHRAS OROMASDES in a circle with PHREN in the centre, while the scene of Tarpeia overwhelmed with shields on the reverse has been left (without its legend) as a representation of the rock-birth. Presumably it was the chance similarity of motifs that suggested the adaptation.
