Once again. May 17 evidently could have corresponded to MARCH 14 (3-14), i.e. to the 'door' to the new year which had advanced 64 days since the time of the Hyades Gate. Heliacal Menkhib (ζ Persei, at his left foot) was no longer in the early northern spring but in early summer:

Possibly the 8 dark nights before the return of Venus as morning star were put in correspondence with the difference between May 16 (136) and May 24 (144 = 12 * 12) - i.e. in correspondence with the difference in time from the 3 later of the 9 Pleiades stars (Alcyone, Atlas, and Pleione) to Hyadum II.

Counting from the left foot of Perseus the glyph Ga2-26 will come 64 days later. 471 - 464 + 1 (0h) + 56 = 64 = 8 + 56:

If there was a correspondence between the seasons of the Sun and the faces of Venus, then we ought to find some sign of those 50 dark nights after the disappearance of Venus as morning star and her return as evening star. Or the creator of the G text may have used the same pattern as the Mayas and counted to 236 (= 472 / 2) = 8 * 29½:

phase	observed periods	periods in the Mayan 'map'	difference
evening star	263	250	- 13
black	8	8	0
morning star	263	236	- 27
black	50	90	+ 40

From the left foot of Perseus (Menkhib, close to the Pleiades) to Rigel (the left foot of the giant Orion) there were 158 (June 7) - 137 (May 17) = 3 weeks.
