Now the serpent and the tree were originally both symbolic of the generative powers of nature, and they were interchangeable. Sometimes one was employed, sometimes the other, and sometimes both. But in that great religious reformation which took place in the faiths of the ancient world about 600 years before the time of Christ, the serpent was degraded, and made to stand as a symbol of Ahriman, the god of evil, who, in the Persic religion, waged incessant war against Ormuzd, the god of beneficence. The Persian myth of the Fall is thus rendered from the Zendavesta by Kalisch:-- "The first couple, the parents of the human race, Meshia and Meshiane, lived originally in purity and innocence. Perpetual happiness was promised them by Ormuzd, the creator of every good gift, if they persevered in their virtue. But an evil demon (Dev) was sent to them by Ahriman, the representative of everything noxious and sinful. He appeared unexpectedly in the form of a serpent, and gave them the fruit of a wonderful tree, Hom, which imparted immortality and had the power of restoring the dead to life. Thus evil inclinations entered their hearts; all their moral excellence was destroyed. Ahriman himself appeared wider the form of the same reptile, and completed the work of seduction. They acknowledged him instead of Ormuzd as the creator of everything good; and the consequence was they forfeited for ever the eternal happiness for which they were destined." Every reader will at once perceive how similar this is to the Hebrew story of the Fall. The similarity is intelligible when we remember that all the literature of the ancient Jews was put into its present form by the learned scribes who returned with the remnant of the people from the Babylonish captivity, and who were full of the ideas that obtained in the Persian religion as reformed by the traditional Zoroaster. As we have said, the Hebrew story of the Fall contains clear relics of Tree and Serpent worship. There is also abundant proof that during the long ages in which the Jews oscillated between polytheism and monotheism this worship largely prevailed. Even up to the reign of Hezekiah, as we find in the Second Book of Kings, the serpent was worshipped in groves, to the great anger of the king, who cast out the idolatry from among his people. Having explained the subject thus, let us now assume with orthodox Christians that the serpent in Eden was animated by the Devil, or was indeed the Devil himself incarnate.
