The Occultists and Theosophists are the first to confess that there is white and black Astrology. Nevertheless, Astrology has to be studied in both aspects by those who wish to become proficient in it; and the good or bad results obtained do not depend upon the principles, which are the same in both kinds, but in the Astrologer himself. Thus Pythagoras, who established the whole Copernican system by the Books of Hermes 2,000 years before Galileo’s predecessor was born, found and studied in them the whole Science of divine Theogony, of the communication with, and the evocation of, the world’s Rectors—the Princes of the “Principalities” of St. Paul—the nativity of each Planet and of the Universe itself, the formulæ of incantations and the consecration of each portion of the human body to the respective Zodiacal sign corresponding to it. All this cannot be regarded as childish and absurd—still less “devilish”—save by those who are, and wish to remain, tyros in the Philosophy of the Occult Sciences. No true thinker—no one who recognises the presence of a common bond between man and visible, as well as invisible, Nature—would see in the old relics of Archaic Wisdom—such as the _Petemenoph Papyrus_, for instance—“childish nonsense and absurdity,” as many Academicians and Scientists have done. But upon finding in such ancient documents the application of the Hermetic rules and laws, such as The consecration of one’s hair to the celestial Nile; of the left temple to the living Spirit in the sun, and in the right one to the spirit of Ammon, he will endeavour to study and comprehend better the “laws of correspondences.” Nor will he disbelieve in the antiquity of Astrology on the plea that some Orientalists have thought fit to declare that the Zodiac was not very ancient, being only the invention of the Greeks of the Macedonian period. For this statement, besides having been shown to be entirely erroneous by a number of other reasons, may be entirely disproved by facts relating to the latest discoveries in Egypt, and by the more accurate readings of hieroglyphics and inscriptions of the earliest dynasties. The published polemics on the contents of the so‐called “Magic” Papyri of the Anastasi collection indicate the antiquity of the Zodiac. As the _Lettres à Lettrone_ say: The papyri discourse at length upon the four bases or Foundations of the world, the identity of which it is impossible, according to Champollion, to mistake, as one is forced to recognise in them the Pillars of the World of St. Paul. It is they who are invoked with the gods of all the celestial zones, quite analogous, once more, to the _Spiritualia nequitiæ in cælestibus_ of the same Apostle.(625)
