“Albertus Magnus, himself an alchemist and student of occult science, as well as a bishop of the Roman Catholic Church, in his enthusiasm for astrology, declared that the zodiacal sign of the celestial virgin rises above the horizon on the twenty-fifth of December, at the moment assigned by the Church for the birth of the Saviour.
The sign and myth of the mother and child were known thousands of years before the Christian era. The drama of the Mysteries of Demeter represents Persephoneia, her daughter, as carried away by Pluto or Hades into the world of the dead; and when the mother finally discovers her there, she has been installed as queen of the realm of Darkness. This myth was transcribed by the Church into the legend of St. Anna going in quest of her daughter Mary, who has been conveyed by Joseph into Egypt. Persephone is depicted with two ears of wheat in her hand; so is Mary in the old pictures; so was the Celestial Virgin of the constellation. Albumazar the Arabian indicates the identity of the several myths as follows:
“In the first decan of the Virgin, rises a maid, called in Arabic, Aderenosa, Adha-nari?, that is, pure immaculate virgin, graceful in person, charming in countenance, modest in habit, with loosened hair, holding in her hands two ears of wheat, sitting upon an embroidered throne, nursing a boy, and rightly feeding him in the place called Hebraea; a boy, I say, named Iessus by certain nations, which signifies Issa, whom they also call Christ in Greek.
At this time Grecian, Asiatic, and Egyptian ideas had undergone a remarkable transformation. The Mysteries of Dionysus-Sabazius had been replaced by the rites of Mithras, whose “caves” superseded the crypts of the former god, from Babylon to Britain. Serapis, or Sri-Apa, from Pontus, had usurped the place of Osiris. The king of Eastern Hindustan, Asoka, had embraced the religion of Siddhartha, and sent missionaries clear to Greece, Asia, Syria, and Egypt, to promulgate the evangel of wisdom. The Essenes of Judea and Arabia, the Therapeutists of Egypt, and the Pythagorists of Greece and Magna Graecia, were evidently religionists of the new faith.
The legends of Gautama superseded the myths of Horus, Anubis, Adonis, Atys, and Bacchus. These were wrought anew into the Mysteries and Gospels, and to them we owe the literature known as the Evangelists and the Apocryphal New Testament. They were kept by the Ebionites, Nazarenes, and other sects as sacred books, which they might “show only to the wise”; and were so preserved till the overshadowing influence of the Roman ecclesiastical polity was able to wrest them from those who kept them.”
