The Phrygian cap reappears in figures related to the first to fourth century religion Mithraism. This astrology-centric Roman mystery cult ("cultus") projected itself with pseudo-Oriental trappings (known as "perserie" in scholarship) in order to distinguish itself from both traditional Roman religion and from the other mystery cults. In the artwork of the cult (e.g. in the so-called "tauroctony" cult images), the figures of the god Mithras as well as those of his helpers Cautes and Cautopates are routinely depicted with a Phrygian cap. The function of the Phrygian cap in the cult are unknown, but it is conventionally identified as an accessory of its "perserie".
