1. Although the Pleiades generally are regarded as 'sisters' (or as other creatures with female characteristics, e.g. doves) there is one exception, viz. Atlas:

Glyph number 465 is evidently connected with Jupiter and the beginning of the Pleiades with Wednesday (Mercury). We must use numbers when we try to understand:

"About Carmenta we know from the historian Dionysus Periergetis that she gave orcales to Hercules and lived to the age of 110 years.

110 was a canonical number, the ideal age which every Egyptian wished to reach and the age at which, for example, the patriarch Joseph died. The 110 years were made up of twenty-two Etruscan lustra of five years each; and 110 years composed the 'cycle' taken over from the Etruscans by the Romans. At the end of each cycle they corrected irregularities in the solar calendar by intercalation and held Secular Games.

The secret sense of 22 - sacred numbers were never chosen haphazardly - is that it is the measure of the circumference of the circle when the diameter is 7. This proportion, now known as pi, is no longer a religious secret; and is used today only as a rule-of-thumb formula, the real mathematical value of pi being a decimal figure which nobody has yet been able work out because it goes on without ever ending, as 22 / 7 does, in a neat recurring sequence [3.142857-142857- ...].

Seven lustra add up to thirty-five years, and thirty-five at Rome was the age at which a man was held to reach his prime and might be elected Consul. (The same age was fixed upon by a Classically-minded Convention as the earliest at which an American might be elected President of the United States.)" (The White Goddess)
