Mithras is the Greek form of Mithra, the central figure of the Roman mystery religion known as Mithraism. The name ultimately derives from the Avestan 𐬨𐬌𐬚𐬭𐬀 (mithra) meaning "oath, covenant, agreement", from an Indo-Iranian root *mitra meaning "that which binds". Etymology and Origins In Zoroastrian mythology, Mithra is a yazata (divine being) of light and friendship, the son of the supreme god Ahura Mazda. The worship of Mithra spread from Persia to the Roman Empire, where it evolved into Mithraism, a distinct Roman mystery cult. While inspired by Iranian tradition, the Roman Mithras had unique imagery and practices, and scholars debate the continuity between Persian and Greco-Roman forms. Mithraism in the Roman World Mithraism was popular among Imperial Roman soldiers from the 1st to the 4th century AD. Initiates underwent seven grades of initiation and called themselves syndexioi ("those united by the handshake"). Worship took place in underground temples called mithraea, or caves, many of which survive across the western Roman Empire, as far south as Roman Africa. The cult's center was Rome itself. Though secretive, Mithraism influenced later religions and left behind numerous archaeological remains. The god Mithras is often depicted slaying a bull (tauroctony), a central icon of the cult.
