The "Mithras Liturgy" is a text from the Great Magical Papyrus of Paris, part of the Greek Magical Papyri, numbered PGM IV.475-834. The modern name by which the text is known originated in 1903 with Albrecht Dieterich, its first translator, based on the invocation of Helios Mithras (Ἥλιοϲ Μίθραϲ) as the god who will provide the initiate with a revelation of immortality. The text is generally considered a product of the religious syncretism characteristic of the Hellenistic and Roman Imperial era, as were the Mithraic mysteries themselves. Some scholars have argued that it has no direct connection to particular Mithraic ritual. Others consider it an authentic reflection of Mithraic liturgy, or view it as Mithraic material reworked for the syncretic tradition of magic and esotericism.
