Giorgio de Santillana (Hamlet’s Mill, 59-60) gives a brief description of the sun’s precessional “year” as it moves through the constellations of the Zodiac:

“The sun’s position among the constellations at the vernal equinox was the pointer that indicated the ‘hours’ of the precessional cycle - very long hours indeed, the equinoctial sun occupying each zodiacal constellation for about 2,200 years. The constellation that rose in the east just before the sun (that is, rose heliacally) marked the ‘place’ where the sun rested. At this time it was known as the sun’s ‘carrier,’ and as the main ‘pillar’ of the sky, the vernal equinox being recognized as the fiducial point of the ‘system,’ determining the first degree of the sun’s yearly circle, and the first day of the year.” Thus, “at time Zero (say, 5000 B.C. . .), the sun was in Gemini; it moved ever so slowly from Gemini into Taurus, then Aries, then Pisces, which it still occupies and will for some centuries more.”

Specifically: “The advent of Christ the Fish marks our age. It was hailed by Virgil, shortly before Anno Domini: ‘a new great order of centuries is now being born. . .’ which earned Virgil the strange title of prophet of Christianity. That’s not all: ‘The preceding age, that of Aries, had been heralded by Moses coming down from Mount Sinai as ‘two-horned,’ that is, crowned with the Ram’s horns, while his flock disobediently insisted upon dancing around the ‘Golden Calf’ that was, rather, a ‘Golden Bull,’ Taurus.”

I’m suspicious of his chronology, but if his dating is accurate, the exodus was not only from Egypt, but from the age of the Bull into the age of the Ram. Eery.
