5. Counting from The Heavenly Gate (at postion 492 + 1) there are 50 days to Ga3-11:

Ga3-12 Ga3-13 (73) Ga3-14 Ga3-15

Allen:

"In astrology, with Scorpio and Pisces, it [the Cancer constellation] was the Watery Trigon; and has been the House of the Moon, from the early belief that this luminary was located here at the creation ..."

"It [Cancer] was sometimes figured as a Crescent, and again as the head of an Arrow ..."

A '2nd rebirth' at Acubens could refer to Moon. The crescent 'jaw' at the top in Ga3-11 together with the 'spear head' (vero) of the preceding tagata (in Ga3-10) could be signs of Cancer.

From Acubens to spring equinox (on Easter Island) there are 50 days:
