Clauss states that inscriptions show Mithras as one of the cults listed on inscriptions by Roman senators who had not converted to Christianity, as part of the "pagan revival" among the elite in the second half of the 4th century. Beck states that "Quite early in the century the religion was as good as dead throughout the empire." However, archaeological evidence indicates the continuance of the cult of Mithras up until the end of the 4thcentury. In particular, large numbers of votive coins deposited by worshippers have been recovered at the Mithraeum at Pons Sarravi (Sarrebourg) in Gallia Belgica, in a series that runs from Gallienus (r. 253–268) to Theodosius I (r. 379–395). These were scattered over the floor when the mithraeum was destroyed, as Christians apparently regarded the coins as polluted; therefore, providing reliable dates for the functioning of the mithraeum up until near the end of the century.
