Mithra VS Jesus: Mithra was born on December 25th of the virgin Anahita. The babe was wrapped in swaddling clothes, placed in a manger and attended by shepherds. He was considered a great traveling teacher and master. He had 12 companions or "disciples." He performed miracles. As the "great bull of the Sun," Mithra sacrificed himself for world peace. He ascended to heaven. Mithra was viewed as the Good Shepherd, the "Way, the Truth and the Light," the Redeemer, the Savior…
He was born of a virgin mother on December 25th, in a humble cave, attended by shepherds, visited by three magi. He became a great traveling teacher and master, followed by twelve disciples. He sacrificed himself and, after three days, ascended to heaven so that others might find eternal life. He embodied Truth, Goodness, and Light. He was the Persian god Mithra, and he existed 2000 years before Christ.
The Mithraeum of the Animals at Ostia antica was excavated by C.L. Visconti in 1867. Near the altar a head of Mithras with Phrygian cap was found (h. 0.45). In the cap are holes for metal rays, so Mithras is depicted as Sol Invictus. Furthermore a head of Sol-Helios was found, with seven holes for rays. The shrine was built in the second half of the second century AD.
