Such probable facts as these must, of course, be referred to a period long anterior to the poetic serpent-symbolism of Egypt, and the elaborate Serpent mythology of Greece and Scandinavia. How simple ideas, having once gained popular prestige, may be caught up by theologians, poets, metaphysicians, and quacks, and modified into manifold forms, requires no proof in an age when we are witnessing the rationalistic interpretations by which the cross, the sacraments, and the other plain symbols are invested with all manner of philosophical meanings. The Serpent having been adopted as the sign-post of Egyptian and Assyrian doctors--and it may have been something of that kind that was set up by Moses in the wilderness--would naturally become the symbol of life, and after that it would do duty in any capacity whatever. An ingenious anthropologist, Mr. C. Staniland Wake, [231] supposes the Serpent in India to have been there also the symbol of præternatural and occult knowledge. Possibly this may have been so to a limited extent, and in post-Vedic times, but to me the accent of Hindu serpent-mythology appears to be emphatically in the homage paid to it as the guardian of the treasures. I may mention here also the theory propounded by Miss A. W. Buckland in a paper submitted to the Anthropological Institute in London, March 10, 1874, on 'The Serpent in connection with Primitive Metallurgy.' In this learned monograph the writer maintains that a connection may be observed between the early serpent-worship and a knowledge of metals, and indeed that the Serpent was the sign of Turanian metallurgists in the same way as I have suggested that in Egypt and Assyria it was the sign of physicians. She believes that the Serpent must have played some part in the original discovery of the metals and precious stones by man, in recognition of which that animal was first assumed as a totem and thence became an emblem. She states that traditional and ornamentational evidences show that the Turanian races were the first workers in metals, and that they migrated westward, probably from India to Egypt and Chaldæa, and thence to Europe, and even to America, bearing their art and its sign; and that they fled before the Aryans, who had the further art of smelting, and that the Aryan myths of serpent-slaying record the overthrow of the Turanian serpent-worshippers.
