Whydid the Romans worship a Persian god? This book presents a new reading of the Mithraic iconography taking intoaccount that the cult had a prophecy. It is likely that the Mithraic reliefsalluded to it and the scenes in the upper panels depict the Golden Age whichwas the final result of many apocalyptic, prophetic texts including the 4thEclogue of Virgil.  The Avesta, theVedas, and Herodotus associate Mithras with the morning star and the dawn andthis god was the mediator between darkness and light. Additionally, Mithras wasa protector of rulers and, similar to Apollo, arbiter and mediator betweenopposite elements, and saviour of humankind. For these reasons he was ideal tobecome the god of Augustus and the Roman emperors.
