He maintains, from the evidence open to him in his day, that it was "Nimrod, that established the sciences of magic and astronomy, the invention of which was subsequently attributed to (the Bactrian) Zoroaster." As we have seen that Nimrod and the Chaldean Zoroaster are the same, the conclusions of the ancient and the modern inquirers into Chaldean antiquity entirely harmonise. Now the secret system of the Mysteries gave vast facilities for imposing on the senses of the initiated by means of the various tricks and artifices of magic. Notwithstanding all the care and precautions of those who conducted these initiations, enough has transpired to give us a very clear insight into their real character. Everything was so contrived as to wind up the minds of the novices to the highest pitch of excitement, that, after having surrendered themselves implicitly to the priests, they might be prepared to receive anything. After the candidates for initiation had passed through the confessional, and sworn the required oaths, "strange and amazing objects," says Wilkinson, "presented themselves. Sometimes the place they were in seemed to shake around them; sometimes it appeared bright and resplendent with light and radiant fire, and then again covered with black darkness, sometimes thunder and lightning, sometimes frightful noises and bellowings, sometimes terrible apparitions astonished the trembling spectators." Then, at last, the great god, the central object of their worship, Osiris, Tammuz, Nimrod or Adonis, was revealed to them in the way most fitted to soothe their feelings and engage their blind affections. An account of such a manifestation is thus given by an ancient Pagan, cautiously indeed, but yet in such a way as shows the nature of the magic secret by which such an apparent miracle was accomplished: "In a manifestation which one must not reveal...there is seen on a wall of the temple a mass of light, which appears at first at a very great distance. It is transformed, while unfolding itself, into a visage evidently divine and supernatural, of an aspect severe, but with a touch of sweetness. Following the teachings of a mysterious religion, the Alexandrians honour it as Osiris or Adonis." From this statement, there can hardly be a doubt that the magical art here employed was none other than that now made use of in the modern phantasmagoria. Such or similar means were used in the very earliest periods for presenting to the view of the living, in the secret Mysteries, those who were dead.
