Many ancient cosmological myths referred to a battle in the sky in which the planet god slays a sky monster, usually a dragon or a serpent. According to the Mayas: "The sun refused to show itself and during four days the world was deprived of light. Then a great star appeared and it was given the name of Quetzacoatl." That means feathered serpent, a term which may indicate a comet with a tail. In other myths, the battle was between Bel and the Dragon, Marduk and Tiamat, Isis and Seth, Vishnu and the Serpent, and Zeus and Typhon. In the Greek myth, the final act of the sky battle takes place at Lake Serbon on the borders of Palestine and Egypt.
Other traditions and myths suggest that the new star, which disrupted the movement of the earth and caused a world conflagration, as a comet which became Venus. Pythagoreans claimed that one of the planets had been a comet, and it is variously described as having had feathers, a beard, horns, a crown of awful splendor, or as scattering its flame in fire.
Velikovsky claimed that Venus was hitherto unknown and that these traditions record its birth. The astronomical charts of the Hindus, Babylonians and Mayas, all of whom were particularly interested in astronomy, show only four planets. In the Hindu table of planets, dated 3100 BCE, Venus alone is absent, and the Babylonians named Venus "the great star that joins the other great stars." Even more significant are the astronomical tablets of the Assyrians, found at Nineveh. They comprised the year-formula of an early king named Ammizaduza, and appear to show either obvious errors or that the orbit of Venus was previously different. Sky charts found in an Egyptian tomb dating from the period of Queen Hatshepsut show the stars in reversed orientation...
