Here the text becomes quite dramatic, during 5 days up to the June solstice in day 172 = 108 + 64:

MARCH 22 23 24 25 (84) 26 27 28 29 (88)
Hb3-1 (101) Hb3-2 Hb3-3 Hb3-4 (104) Hb3-5 Hb3-6 Hb3-7 Hb3-8 (108)
AIN *66 *67 ALDEBARAN *69 *70 *71 *72
APRIL 14 (104) 15 16 17 (471 - 364) 18 (108 = 172 - 64)
Hb3-24 (108 + 16) Hb3-25 (5 * 5 * 5) Hb3-26 (2 * 63) Hb3-27 (127) Hb3-28 (2 * 64)
BETELGEUZE PRAJA-PĀTI *90 *91 *92 = 172 - 80

Betelgeuze (the 'Moist One') is located on the brink ot the Milky Way river and Praja-pāti (the 'Lord of Created Beings') is high up at 6h in Auriga:

6h implies the equinox cycle had moved 6h / 24h = 25 % around the anciently defined precessional cycle of 26,000 years, i.e. 0.25 * 26,000 = 26,000 / 4 = 6,500 years.

And the Sphinx would have seen Leo in the east with Orion in the south around B.C. 8800 according to the diagram above, i.e. around 2000 + 8800 = 10800 years ago.

Regulus (*152) - Betelgeuze (*88) = *64.

... Ogotemmêli had his own ideas about calculation. The Dogon in fact did use the decimal system, because from the beginning they had counted on their fingers, but the basis of their reckoning had been the number eight and this number recurred in what they called in French la centaine, which for them meant eighty. Eighty was the limit of reckoning, after which a new series began. Nowadays there could be ten such series, so that the European 1,000 corresponded to the Dogon 800. But Ogotemmêli believed that in the beginning men counted by eights - the number of cowries on each hand, that they had used their ten fingers to arrive at eighty, but that the number eight appeared again in order to produce 640 (8 x 10 x 8). 'Six hundred and forty', he said, 'is the end of the reckoning.'
