Thus, if the commencement of the year went back 30 days every 120 years, this commencement of the year, continuing to recede, would, at the end of 12 times 120 years, or of 1460 years get back to the Solstitial point, or primitive point of departure of the period. The Sun would then have made but 1459 revolutions though 1460 were counted; to make up which, a year more would need to be added. So that the Sun would not have made his 1460 revolutions until the end of 1461 years of 365 days each,—each revolution being in reality not 365 days exactly, but 365-l/4.
This period of 1461 years, each of 365 days, bringing back the commencement of the Solar year to the Solstitial point, at the rising of Sirius, after 1460 complete Solar revolutions, was called in Egypt the Sothiac period, the point of departure whereof was the Summer Solstice, first occupied by the Lion and afterward by Cancer, under which sign is Sirius, which opened the period. It was, says Porphyry, at this Solstitial New Moon, accompanied by the rising of Seth or the Dog-Star, that the beginning of the year was fixed, and that of the generation of all things, or, as it were, the natal hour of the world.
Not Sirius alone determined the period of the rising of the Nile. Aquarius, his urn, and the stream flowing from it, in opposition to the sign of the Summer Solstice then occupied by the Sun, opened in the evening the march of Night, and received the full Moon in his cup. Above him and with him rose the feet of Pegasus, struck wherewith the waters flow forth that the Muses drink. The Lion and the Dog, indicating, were supposed to cause the inundation, and so were worshipped. While the Sun passed through Leo, the waters doubled their depth; and the sacred fountains poured their streams through the heads of lions. Hydra, rising between Sirius and Leo, extended under three signs. Its head rose with Cancer, and its tail with the feet of the Virgin and the beginning of Libra; and the inundation continued while the Sun passed along its whole extent.
The successive contest of light and darkness for the possession of the lunar disk, each being by turns victor and vanquished, exactly resembled what passed upon the earth by the action of the Sun and his journeys from one Solstice to the other. The lunary revolution presented the same periods of light and darkness as the year, and was the object of the same religious fictions. Above the Moon, Pliny said, everything is pure, and filled with eternal light. There ends the cone of shadow which the earth projects, and which produces night; there ends the sojourn of night and darkness; to it the air extends; but there we enter the pure substance.
The Egyptians assigned to the Moon the demiurgic or creative force of Osiris, who united himself to her in the spring, when the Sun communicated to her the principles of generation which she afterward disseminated in the air and all the elements. The Persians considered the Moon to have been impregnated by the Celestial Bull, first of the signs of spring. In all ages, the Moon has been supposed to have great influence upon vegetation, and the birth and growth of animals; and the belief is as widely entertained now as ever, and that influence regarded as a mysterious and inexplicable one. Not the astrologers alone, but Naturalists like Pliny, Philosophers like Plutarch and Cicero, Theologians like the Egyptian Priests, and Metaphysicians like Proclus, believed firmly in these lunar influences.
"The Egyptians," says Diodorus Siculus, "acknowledged two great gods, the Sun and Moon, or Osiris and Isis, who govern the world and regulate its administration by the dispensation of the seasons…. Such is the nature of these two great Divinities, that they impress an active and fecundating force, by which the generation of beings in effected; the Sun, by heat and that spiritual principle that forms the breath of the winds; the Moon by humidity and dryness; and both by the forces of the air which they share in common. By this beneficial influence everything is born, grows, and vegetates. Wherefore this whole huge body, in which nature resides, is maintained by the combined action of the Sun and Moon, and their five qualities,—the principles spiritual, fiery, dry, humid, and airy."
So five primitive powers, elements, or elementary qualities, are united with the Sun and Moon in the Indian theology,—air, spirit, fire, water, and earth: and the same five elements are recognized by the Chinese. The Phoenicians, like the Egyptians, regarded the Sun and Moon and Stars as sole causes of generation and destruction here below.
The Moon, like the Sun, changed continually the track in which she crossed the Heavens, moving ever to and fro between the upper and lower limits of the Zodiac; and her different places, phases, and aspects there, and her relations with the Sun and the constellations, have been a fruitful source of mythological fables.
All the planets had what astrology termed their houses, in the Zodiac. The House of the Sun was in Leo, and that of the Moon in Cancer. Each other planet had two signs; Mercury had Gemini and Virgo; Venus, Taurus and Libra; Mars, Aries and Scorpio; Jupiter, Pisces and Sagittarius; and Saturn, Aquarius and Capricornus. From this distribution of the signs also came many mythological emblems and fables; as also many came from the places of exaltation of the planets. Diana of Ephesus, the Moon wore the image of a crab on her bosom, because in that sign was the Moon's domicile; and lions bore up the throne of Horus, the Egyptian Apollo, the Sun personified, for a like reason: while the Egyptians consecrated the tauriform scarabæsus to the Moon, because she had her place of exaltation in Taurus; and for the same reason Mercury is said to have presented Isis with a helmet like a bull's head.
A further division of the Zodiac was of each sign into three parts of 10° each, called Decans, or, in the whole Zodiac, 36 parts, among which the seven planets were apportioned anew, each planet having an equal number of Decans, except the first, which, opening and closing the series of planets five times repeated, necessarily had one Decan more than the others. This subdivision was not invented until after Aries opened the Vernal Equinox; and accordingly Mars, having his house in Aries, opens the series of decans and closes it; the planets following each other, five times in succession, in the following order, Mars, the Sun, Venus, Mercury, the Moon, Saturn, Jupiter, Mars, etc.; so that to each sign are assigned three planets, each occupying 10 degrees. To each Decan a God or Genius was assigned, making thirty-six in all, one of whom, the Chaldeans said, came down upon earth every ten days, remained so many days, and re-ascended to Heaven. This division is found on the Indian sphere, the Persian, and that Barbaric one which Aben Ezra describes. Each genius of the Decans had a name and special characteristics. They concur and aid in the effects produced by the Sun, Moon, and other planets charged with the administration of the world: and the doctrine in regard to them, secret and august as it was held, was considered of the gravest importance; and its principles, Firmicus says, were not entrusted by the ancients, inspired as they were by the Deity, to any but the Initiates, and to them only with great reserve, and a kind of fear, and when cautiously enveloped with an obscure veil, that they might not come to be known by the profane.
