... Like archaic China and certain Amero-Indian societies, Europe, until quite recently, celebrated a rite involving the extinguishing and renewal of domestic fires, preceded by fasting and the use of the instruments of darkness. This series of events took place just before Easter, so that the 'darkness' which prevailed in the church during the service of the same name (Tenebrae), could symbolize both the extinguishing of domestic fires and the darkness which covered the earth at the moment of Christ's death. In all Catholic countries it was customary to extinguish the lights in the churches on Easter Eve and then make a new fire sometimes with flint or with the help of a burning-glass. Frazer brings together numerous instances which show that this fire was used to give every house new fire ...

... And so they waited there in the darkness at the place where the sun rises. At length the day dawned, a chilly grey at first, then flaming red. And the sun came up from his pit, suspecting nothing. His fire spread over the mountains, and the sea was all glittering. He was there, the great sun himself, to be seen by the brothers more closely than any man had ever seen him. He rose out of the pit until his head was through the noose, and then his shoulders. Then Maui shouted, and the ropes were pulled, the noose ran taut.

The sun screamed out, and groaned and shrieked, and Maui struck him savage blows, until the sun was begging him for mercy. The brothers held the ropes tight, as they had been told, and held on for a long time yet. Then at last when Maui gave the signal they let him go, and the ropes came loose, and the sun crept slowly and feebly on his course that day, and has done ever since. Hence the days are longer than they formerly were. It was during this struggle with the sun that his second name was learned by man. At the height of his agony the sun cried out: 'Why am I treated by you in this way? Do you know what it is you are doing. O you men? Why do you wish to kill Tama nui te ra?' This was his name, meaning Great Son of the Day, which was never known before ...

When around 10500 BC the Leo constellation had risen with the Sun at the northern spring equinox (0h) Orion would have been there a quarter of a year earlier in midwinter. Right ascension increases towards the east. From Betelgeuze (*88) to Regulus (*152) there were *64 right ascension days. The Sphinx pointed at Leo and the 3 great pyramids towards the triplet of stars in Orion's Belt (Tau-toru) which came earlier in the year:
