Three Wise Men
The idea of three wise men or kings is astrological and Druidic in origin. The four animals depicted around the Christ represent the four cardinal signs of the zodiac. The three wise men, shepherds, or kings, represent the constellation of Orion through which the soul of "great kings" was believed to incarnate and then depart. The figure of the Virgin Mary represents the night sky. This particular artist suggests the round of the zodiac by the circular hem of the Madonna's cloak. Christ is the sun born into the sign of Virgo, the Virgin. Joseph, the "Carpenter" looks up toward the heavens. He is contemplating the signs, and represents the ancient gnosis suppressed by the Church of Rome. In Egyptian the word for "carpenter" was Setepenre. This word was one of the titles for a pharaoh. Jesus was indeed of a pharaonic bloodline, as the painting figuratively connotes. The man standing at the back right carrying the lamb represents the Cult of Atonists who observed the sun's move from the sign of Taurus into Aries. The ass or donkey is still used as a symbol today in US politics. The ass represents the god Set and the Hyksos Kings of Lower Egypt. The bull represents the Amenists of Upper Egypt, as well as the Irish Druids. The Roman columns emphasize Jesus' Roman ancestry.
In the New Testament, the three "wise men" who allegedly visited the stable where Jesus was born, represent the three aligned stars of Orion. This is because the Jesus story, like many other myths, is astrological (or sidereal) in nature. It is not the biography of a man who physically lived, at least as the New Testament portrays him.
