There is very little known, or at least recorded, concerning the nature of the god Set. Light research will reveal little other than the legendary battles between Set and Horus, which owe to middle and late dynastic times by which time Set had become thoroughly demonised. It was not always that way, since Set was originally the only begotten son (or star) of Nuit, by divine parthenogenesis. As such, Set is identical to Hadit, for he is the manifester of Nuit through her star.

Some of the mysteries of Set can be found in the Sethian Gnosis, which forms part of the collection of works attributed to Hermes Trismegistus. There we find a unique non-dualistic cosmological trinity, where light and darkness are permeated by spirit or fragrance, forming the matrix for manifestation. The mystery deepens with the Gnostic scriptures of Set. In Pistis Sophia the name of Jesus is said to be ABERAMENTHO. While to most Christians the name is that of a historical personage, the Graeco-Egyptian name clearly means, “image (or likeness) of Ra-Menthu”. The Coptic name, which begins with alpha and ends with omega, adds Qabalistically to the number 1013. The name identifies the Gnostic Christ with Set-Typhon as the Initiator. The Qabalah indicates there is more to “likeness” than mere similarity, for the number 1013 is that of syzygy, a word indicative of a method by which one knows ‘through another’. The polar twin or double is central to the elemental magick of the ancient Egyptian priesthood of Set. The surviving fragments of this knowledge were attributed to the Greek god Hermes (Roman Mercury) to obscure the fact that it was derived from Egypt, the “black land” of Khem-menthu.
Menthu is the name of the god that appears on the obverse of the Stele of Revealing. The fact that this god, the “Lord of Thebes”, is commonly held to be Ra Hoor Khuit, or Horakhty, serves as a convenient veil drawn over the identification with Set. This god Menthu or Set of the ancient Theban cult of Thelema, then, embodies the attributes of Ra, Horus, Set and Apophis (as serpent) in one image. Study of the hieroglyphics on the obverse and reverse of the Stele demonstrates that Kenneth Grant was not mistaken when he insisted that Thelema, or the Egyptian Book of the Law, Liber AL vel Legis, veils the cult of Set-Typhon.
Set and the Solstice
We tend to focus on the spiritual and magical import of the Capricorn solstice, since the industrial commercialisation of Christmas sweeps all else away. The hedonist revelry is all the more bizarre considering its principal icon, Santa, is derived from an obscure Roman Catholic anointed luminary, St Nicholas! Nonetheless, three days after the winter solstice the Light is most certainly born into the darkness of the world—whether the world cares or not.

Socrates and his modern day adorants prefer the naturalistic explanation of supernatural phenomena, which does not dare contradict the sacred shrine of science (astronomy in this case). While asceticism demands that visible nature is abhorrent, pre-religious spiritual doctrines assert that visible nature is the form of the formless, even a miraculous demonstration, to use latter day terms, of the existence of God. This cannot of course be proved by argument, persuasion, reason or fact, since the miracle is entirely in the eye of the beholder. While nature is the object here, our doctrine asserts there are no objects as such and that all worlds of existence arise from pure subjectivity. For that reason, the nature of Set is impossible to pin down, for he is both the pin and the thing pinned; he is the hook, the line and the sinker; the cross (way) and the one crucified; the stone of the wise, the stone for stumbling and the one that stumbles.
If we look to the Pyramid Texts, we find that the ancient Egyptians, shrewd in such matters, depicted the serpent (cognate with messiah) going forth on two legs—when everyone knows the serpent is uniquely identified by the fact of having no legs. Thus do we go forth, be it in darkness or light!
The Egyptian and Thelemic New Year
It is no accident that Saturn should be Lord of two signs and not one, though the harmony was not realised by modern astrologers who wished to align their particular form of black art with profane science. They thus wheeled in the outer planets as new rulers of Capricorn, Scorpio and Pisces, invoking the Lords of Unbalanced Force. Aleister Crowley had a much better idea of what to do with the outer planets in astrology but his idea was not taken up—it requires Qabalistic knowledge before it can be understood (Ref. The Book of Thoth).
The ancient Egyptians marked the New Year by the reappearance of Sirius or Set, “who came first before the gods”. The appearance of Sirius coincided with the Nile flood. Though it is a break from mainstream tradition, the Thelemic New Year begins with the Capricorn solstice. So far as nature is concerned, this is so obvious as not to require an explanation. We could also term this the Qabalistic or Platonic New Year, while bearing in mind that Plato learned it all from the Egyptian priesthood. So let us focus on Khem. Set was, and is, the Opener of the Year, and for that reason was always present at the coronation of a pharaoh. As the child of Nuit he is her manifesting star. Now if we follow the natural progression of that wondrous Decad, the Tree of Life, we will see how the year is mapped out in spiritual terms and follows the Sword and Serpent, evolution and involution:
Opening the year, Capricorn ruled by Saturn (Binah and the supernal wisdom). Next, Aquarius, also ruled by Saturn. The pair forms the ‘winter cup’ in which the light is born—the son (sun) of Nuit. After Aquarius comes Pisces, ruled by Jupiter (Chesed). Next, Aries ruled by Mars (Geburah) and the first equinox of the year. After Aries comes Taurus, ruled by Venus (Netzach). Next, Gemini ruled by Mercury (Hod), then, at summer solstice, Cancer ruled by the Moon (Yesod). With the sign of Leo, ruled by the Sun, Malkuth is brought to Tiphereth via the Alchemical Wedding of Sun and Moon. From here we begin the ascent via the Serpent: Virgo is ruled by Mercury (Hod), and next, at the second equinoctial gate of the year, comes Libra ruled by Venus (Netzach). Then comes Scorpio ruled by Mars (Geburah). Finally, Sagittarius ruled by Jupiter (Chesed). The end is with the beginning as we once more enter the Capricorn solstice.
