Thus, in one sense, Rā is father of all the gods; but in another Ptah is the creator of the egg of the sun because Capella setting heralded sunrise at a particular time of the year; and Isis is the _mother_ of Horus because Phact = α Columbæ, Serk-t = α Centauri, Mut = γ Draconis, and other stars (Isis) did precisely the same; while in another connection Isis is the sister of Osiris, and therefore the _mother_ of Horus. But here the relationship depends upon the association of the moon and warning star in the morning sky. I only offer these as suggestions; similar variations might be multiplied _ad nauseam_. But while all this proves that genealogies may be manufactured without either end or utility, we gather that the association of mythological personages with definite astronomical bodies may in time be of great help in such inquiries, and ultimately enable us to raise the veil of mystery by which these old ideas have of set purpose, and partly by these means, been hidden. There seems no doubt that we have got definite evidence that the very oldest mythological personages were closely connected either with the sun at some special time of the year, with the moon, or with the rising and setting of some star or another. Hence we ought to be able from the temple evidence to classify the northern and southern gods. _Northern Gods and Goddesses._ GOD. GODDESS. Ptah = Capella, April sun (1) Bast-Isis = α Ursæ Majoris. Anubis = Northern constellations. Taurt-Isis = {α Ursæ Majoris. {γ Draconis. {Min: {Khem = May Sun (2). Menat-Isis Spica. Autumn Sun Serk-t-Isis Antares. Spring Sun Nit-Isis Pleiades. _Southern Gods and Goddesses._ Osiris = Moon-god. Chnemu = Sun-god, autumnal equinox. Khonsu = Canopus, autumnal equinox, warner. West horizon followed by Serk-t = α Centauri east horizon. Amen-Rā A combined north and Teχi-Isis } Phact (1) south god, established Amen-t-Isis } Sirius (2) about 3700 B.C. Hathor-Isis } The establishment of Amen-Rā gives us a fair indication of the changes which must have taken place among the early civilisations when the beginning of the year was altered. There can be no doubt, I think, that Chnemu was the first Sun-god of Southern Egypt; the cryosphinxes at Thebes are alone sufficient to prove it;[166] and if so, then the southern people must have come from a region where the autumnal equinox marked the most important time of the year for their agricultural operations. And this year had eventually to give way, as we know it did, about 3700 B.C., for one beginning at the summer solstice.
