THE D TABLET
 

This implies we should not read Da1-1 as the place for heliacal Antares, it should instead be the place for nakshatra Antares - he should be visible:

Nov 25 (329) 26 27 28 (332) 29 30

*66 *67 ALDEBARAN *69 *70 TABIT
May 26 (146) 27 28 29 30 31 (151)

When Antares would be visible close to the right ascension line connected with the Full Moon (nakshatra Antares) it had ideally to be in May 26 (2 * 73) because *249 - *366 / 2 = *66 (May 26). So let's move on.

When the Explorers sailed away from their old homeland it was in April 25 (115 → Mercury) and they arrived to Easter Island in June 1 (152 = 115 + 37). Which was 20 days before the southern winter solstice in June 21 [E:17].

The extraordinary reversed Rei with no 'leaves' was presumably drawn at Da1-11 because here, ideally, the head of the upside down Giant (Ras Algethi, α Herculi) could be observed at the time line of the Full Moon.

Which ought to mean the Sun would be reaching an opposite kind of place, viz. where his return was due, i.e. to Cursa (the Footstool of the Giant → Orion):

The left foot of Orion was Rigel (β Orionis), 2 days after Cursa and 6 days after June 1, and above the head of the Hare:

Above, and at the same time, was the Auriga constellation with the very bright star Capella (the Goat Mother):

ELNATH NIHAL

It was on page 17 in Manuscript E that the dates for the journey of the Explorers was documented. The hint of 17 could have been referring (or alluding) to the right ascension position of Nihal (β Leporis) in the Golden Age of the Bull, viz. APRIL 7 (97 = 80 + 17)..

Lepus was in front of the right foot of Orion.
