These 8 and 50 dark nights had been imprinted in the minds of all people since time began. In Hb9-50, we should remember, a pair of stars were used to indicate the 3rd night of Friday (the day of Venus) - presumably also marking the end of the 50 black nights before Venus was returning as evening star:

Greek zeta

Ζ (ζ)

... Zeta (uppercase Ζ, lowercase ζ; Greek: ζήτα ... is the sixth letter of the Greek alphabet. In the system of Greek numerals, it has a value of 7. It was derived from the Phoenician letter Zayin. Letters that arose from zeta include the Roman Z and Cyrillic З ...

Zayin (also spelled Zain or Zayn or simply Zay) is the seventh letter of many Semitic abjads ... It represents the sound [z]. The Phoenician letter appears to be named after a sword or other weapon. (In Biblical Hebrew, 'Zayin' means sword, and the verb 'Lezayen' means to arm. In modern Hebrew, 'zayin' means penis and 'lezayen' is a vulgar term which generally means to perform sexual intercourse and is used in a similar fashion to the English word fuck, although the older meaning survives in 'maavak mezuyan' (armed struggle) and 'beton mezuyan' (armed, i.e., reinforced concrete). The Proto-Sinaitic glyph according to Brian Colless may have been called ziqq, based on a hieroglyph depicting a 'manacle'.

to Al Tarf - the End of the journey at the 'Upraised Reef' seems to have been 8 + 68 days:

The precession moved the stars ahead in the Sun calendar and it was therefore necessary to sometimes adjust the structure to a new place.

... Men's spirits were thought to dwell in the Milky Way between incarnations. This conception has been handed down as an Orphic and Pythagorean tradition fitting into the frame of the migration of the soul. Macrobius, who has provided the broadest report on the matter, has it that souls ascend by way of Capricorn, and then, in order to be reborn, descend again through the 'Gate of Cancer'. Macrobius talks of signs; the constellations rising at the solstices in his time (and still in ours) were Gemini and Sagittarius: the 'Gate of Cancer' means Gemini. In fact, he states explicitly (I,12.5) that this 'Gate' is 'where the Zodiac and the Milky Way intersect'. Far away, the Mangaians of old (Austral Islands, Polynesia), who kept the precessional clock running instead of switching over to 'signs', claim that only at the evening of the solstitial days can spirits enter heaven, the inhabitants of the northern parts of the island at one solstice, the dwellers in the south at the other ... Considering the fact that the crossroads of ecliptic and Galaxy are crisis-resistant, that is, not concerned with the Precession, the reader may want to know why the Mangaians thought they could go to heaven only on the two solstitial days. Because, in order to 'change trains' comfortably, the constellations that serve as 'gates' to the Milky Way must 'stand' upon the 'earth', meaning that they must rise heliacally either at the equinoxes or at the solstices. The Galaxy is a very broad highway, but even so there must have been some bitter millenia when neither gate was directly available any longer, the one hanging in midair, the other having turned into a submarine entrance ...
