Ormuzd or Osiris, the beneficent Principle that gives the world light, was personified by the Sun, apparent source of light. Darkness, personified by Typhon or Ahriman, was his natural enemy. The Sages of Egypt described the necessary and eternal rivalry or opposition of these principles, ever pursuing one the other, and one dethroning the other in every annual revolution, and at a particular period, one in the Spring under the Bull, and the other in Autumn under the Scorpion, by the legendary history of Osiris and Typhon, detailed to us by Diodorus and Synesius; in which history were also personified the Stars and constellations Orion, Capella, the Twins, the Wolf, Sirius, and Hercules, whose risings and settings noted the advent of one or the other equinox.

Plutarch gives us the positions in the Heavens of the Sun and Moon, at the moment when Osiris was murdered by Typhon. The Sun, he says, was in the Sign of the Scorpion, which he then entered at the Autumnal Equinox. The Moon was full, he adds; and consequently, as it rose at sunset, it occupied Taurus, which, opposite to Scorpio, rose as it and the Sun sank together, so that she was then found alone in the sign Taurus, where, six months before, she had been in union or conjunction with Osiris, the Sun, receiving from him those germs of universal fertilization which he communicated to her. It was the sign through which Osiris first ascended into his empire of light and good. It rose with the Sun on the day of the Vernal Equinox; it remained six months in the luminous hemisphere, ever preceding the Sun and above the horizon during the day; until in Autumn, the Sun arriving at Scorpio, Taurus was in complete opposition with him, rose when he set, and completed its entire course above the horizon during the night; presiding, by rising in the evening, over the commencement of the long nights. Hence in the sad ceremonies commemorating the death of Osiris, there was borne in procession a golden bull covered with black crape, image of the darkness into which the familiar sign of Osiris was entering, and which was to spread over the Northern regions, while the Sun, prolonging the nights, was to be absent, and each to remain under the dominion of Typhon, Principle of Evil and Darkness.

Setting out from the sign Taurus, Isis, as the Moon, went seeking for Osiris through all the superior signs, in each of which she became full in the successive months from the Autumnal to the Vernal Equinox, without finding him in either. Let us follow her in her allegorical wanderings.

Osiris was slain by Typhon his rival, with whom conspired a Queen of Ethiopia, by whom, says Plutarch, were designated the winds. The paranatellons of Scorpio, the sign occupied by the Sun when Osiris was slain, were the Serpents, reptiles which supplied the attributes of the Evil Genii and of Typhon, who himself bore the form of a serpent in the Egyptian planisphere. And in the division of Scorpio is also found Cassiopeia, Queen of Ethiopia, whose setting brings stormy winds.

Osiris descended to the shades or infernal regions. There he took the name of Serapis, identical with Pluto, and assumed his nature. He was then in conjunction with Serpentarius, identical with Æsculapius, whose form he took in his passage to the lower signs, where he takes the names of Pluto and Ades.

Then Isis wept for the death of Osiris, and the golden bull covered with crape was carried in procession. Nature mourned the impending loss of her Summer glories, and the advent of the empire of night, the withdrawing of the waters, made fruitful by the Bull in Spring, the cessation of the winds that brought rains to swell the Nile, the shortening of the days, and the despoiling of the earth. Then Taurus, directly opposite the Sun, entered into the cone of shadow which the earth projects, by which the Moon is eclipsed at full, and with which, making night, the Bull rises and descends as if covered with a veil, while he remains above our horizon.

The body of Osiris, enclosed in a chest or coffin, was cast into the Nile. Pan and the Satyrs, near Chemmis, first discovered his death, announced it by their cries, and everywhere created sorrow and alarm. Taurus, with the full Moon, then entered into the cone of shadow, and under him was the Celestial River, most properly called the Nile, and below, Perseus, the God of Chemmis, and Auriga, leading a she-goat, himself identical with Pan, whose wife Aiga the she-goat was styled.

Then Isis went in search of the body. She first met certain children who had seen it, received from them their information, and gave them in return the gift of divination. The second full Moon occurred in Gemini, the Twins, who presided over the oracles of Didymus, and one of whom was Apollo, the God of Divination.

She learned that Osiris had, through mistake, had connection with her sister Nephte, which she discovered by a crown of leaves of the melilot, which he had left behind him. Of this connection a child was born, whom Isis, aided by her dogs, sought for, found, reared, and attached to herself, by the name of Anubis, her faithful guardian. The third full Moon occurs in Cancer, domicile of the Moon. The paranatellons of that sign are, the crown of Ariadne or Proserpine, made of leaves of the melilot, Procyon and Canis Major, one star of which was called the Star of Isis, while Sirius himself was honored in Egypt under the name of Anubis.

Isis repaired to Byblos, and seated herself near a fountain, where she was found by the women of the Court of a King. She was induced to visit his Court, and became the nurse of his son. The fourth full Moon was in Leo, domicile of the Sun, or of Adonis, King of Byblos. The paranatellons of this sign are the flowing water of Aquarius, and Cepheus, King of Ethiopia, called Regulus, or simply The King. Behind him rise Cassiopeia his wife, Queen of Ethiopia, Andromeda his daughter, and Perseus his son-in-law, all paranatellons in part of this sign, and in part of Virgo.
