The god Mithras (or Mithra) was a major influence on Christianity until the fourth century C.E. In this version of his story, by Barbara Walker, the parallels between the two cults are emphasized.
Mithra [was the] Persian savior, whose cult was the leading rival of Christianity in Rome, and more successful than Christianity for the first four centuries of the "Christian" era. In 307 A.D. the emperor officially designated Mithra "Protector of the Empire."
Christians copied many details of the Mithraic mystery-religion, explaining the resemblance later with their favorite argument, that the devil had anticipated the true faith by imitating it before Christ's birth. Some resemblances between Christianity and Mithraism were so close that even St. Augustine declared the priests of Mithra worshipped the same deity as he did.
Mithra was born on the 25th of December, called "Birthday of the Unconquered Sun," which was finally taken over by Christians in the 4th century A.D. as the birthday of Christ. Some said Mithra sprang from an incestuous union between the sun god and his own mother, just as Jesus, who was God, was born of the Mother of God. Some claimed Mithra's mother was a mortal virgin. Others said Mithra had no mother, but was miraculously born of a female Rock, the petra genetrix, fertilized by the Heavenly Father's phallic lightning.
Mithra's birth was witnessed by shepherds and by Magi who brought gifts to his sacred birth-cave of the Rock. Mithra performed the usual assortment of miracles: raising the dead, healing the sick, making the blind see and the lame walk, casting out devils. As a Peter, son of the petra, he carried the keys of the kingdom of heaven. His triumph and ascension to heaven were celebrated at the spring equinox (Easter), when the sun rises toward its apogee.
Before returning to heaven, Mithra celebrated a Last Supper with his twelve disciples, who represented the twelve signs of the zodiac. In mem-
