The religion of Mithraism spread throughout the Roman Empire, but has hitherto not been attested on Malta. Because of its secretive nature, and the small subterranean shrines which constituted its places of worship, evidence for Mithraism has always been difficult to find, but in this study Claudia Sagona re-evaluates a range of iconographic and architectural evidence which has hitherto been seen in an Early Christian context, to show that at least some Mithraic cult activity was present in the Maltese Archipelago.
