In the C text, this symbol has been placed at the solstice in Roman times, viz. at χ Carinae. Here was the point of turning around from moving up to moving down:

... The four bereaved and searching divinities, the two mothers and their two sons, were joined by a fifth, the moon-god Thoth (who appears sometimes in the form of an ibis-headed scribe, at other times in the form of a baboon), and together they found all of Osiris save his genital member, which had been swallowed by a fish.

They tightly swathed the broken body in linen bandages, and when they performed over it the rites that thereafter were to be continued in Egypt in the ceremonial burial of kings, Isis fanned the corpse with her wings and Osiris revived, to become the ruler of the dead. He now sits majestically in the underworld, in the Hall of the Two Truths, assisted by forty-two assessors, one from each of the principal districts of Egypt; and there he judges the souls of the dead. These confess before him, and when their hearts have been weighed in a balance against a feather, receive, according to their lives, the reward of virtue and the punishment of sin ...

Or as it was explained in Polynesia: there was a change of sex:

... When this tremendous task had been accomplished Atea took a third husband, Fa'a-hotu, Make Fruitful. Then occurred a curious event. Whether Atea had wearied of bringing forth offspring we are not told, but certain it is that Atea and her husband Fa'a-hotu exchanged sexes. Then the [male] eyes of Atea glanced down at those of his wife Hotu and they begat Ru. It was this Ru who explored the whole earth and divided it into north, south, east, and west ...

The reason seems to be the conjuntion between Canopus (Agastya, Eridu) and Mirzam (β at the right front paw of Canis Major), cfr Ba1-21 (→ day 121 = Beltane):

... The Pythagoreans make Phaeton fall into Eridanus, burning part of its water, and glowing still at the time when the Argonauts passed by. Ovid stated that since the fall the Nile hides its sources. Rigveda 9.73.3 says that the Great Varuna has hidden the ocean. The Mahabharata tells in its own style why the 'heavenly Ganga' had to be brought down. At the end of the Golden Age (Krita Yuga) a class of Asura who had fought against the 'gods' hid themselves in the ocean where the gods could not reach them, and planned to overthrow the government. So the gods implored Agastya (Canopus, alpha Carinae = Eridu) for help. The great Rishi did as he was bidden, drank up the water of the ocean, and thus laid bare the enemies, who were then slain by the gods. But now, there was no ocean anymore! Implored by the gods to fill the sea again, the Holy One replied: 'That water in sooth hath been digested by me. Some other expedient, therefore, must be thought of by you, if ye desire to make endeavour to fill the ocean ...
