MITHRAISM: ROME AND CHRISTIANITY

Sunday was kept holy in honor of Mithra… The 25 December was observed as his birthday, the natalis invicti, the rebirth of the winter-sun, unconquered by the rigors of the season.

Mithra is the god of light, Anaitis the goddess of water. Independently of the Zoroastrian reform, Mithra retained his place as foremost deity in the north-west of the Iranian highlands. After the conquest of Babylon this Persian cult came into contact with Chaldean astrology and with the national worship of Marduk.

For a time the two priesthoods of Mithra and Marduk (magi and chaldaei respectively) coexisted in the capital and Mithraism borrowed much from this intercourse. This modified Mithraism traveled farther north-westward and became the State cult of Armenia. Its rulers, anxious to claim descent from the glorious kings of the past, adopted Mithradates as their royal name (so five kings of Georgia, and Eupator of the Bosporus).

Mithraism then entered Asia Minor, especially Pontus and Cappadocia. Here it came into contact with the Phrygian cult of Attis and Cybele from which it adopted a number of ideas and practices, though apparently not the gross obscenities of the Phrygian worship.

This Phrygian-Chaldean-Indo-Iranian religion, in which the Iranian element remained predominant, came, after Alexander's conquest, in touch with the Western World. Hellenism, however, and especially Greece itself, remained remarkably free from its influence.

When finally the Romans took possession of the Kingdom of Pergamum, occupied Asia Minor and stationed two legions of soldiers on the Euphrates, the success of Mithraism in the West was secured. It spread rapidly from the Bosporus to the Atlantic, from Illyria to Britain.

Its foremost apostles were the legionaries; hence it spread first to the frontier stations of the Roman army.
