The mystic title of the celebrated Hermetic fragment with which this volume commences, "Koré Kosmou" that is, the "Kosmic Virgin," is in itself a revelation of the wonderful identity subsisting between the ancient wisdom-religion of the old world, and the creed of catholic Christendom. Koré is the name by which, in the Eleusinian Mysteries, Persephone the Daughter, or Maiden, was saluted; and it is also-perhaps only by coincidence-the Greek word for the pupil or apple of the eye. When, however, we find Isis, the Moon-goddess and Initiatrix, in her discourse with Horos, mystically identifying the eye with the soul, and comparing the tunics of the physical organ of vision with the envelopes of the soul; when, moreover, we reflect that precisely as the eye, by means of its pupil, is the enlightener and percipient of the body, so is the soul the illuminating and seeing principle of man, we can hardly regard this analogy of names as wholly unintentional and uninstructive. For Koré, or Persephone, the Maiden, is the personified soul, whose "apostasy," or "descent," from the heavenly sphere into earthly generation, is the theme of the following Hermetic parable.
