Phallic worship has been practiced by many varied and widespread cultures throughout the world for thousands of years. The male phallic was recognized as the bringer of life and the progenitor of the human race. As with many ancient cultures, a more complete understanding of the phenomena of sexual intercourse was to remain a mystery and, even by today's standards, some of those mysteries remain. It is evident that the belief of the reciprocal principles of nature, male and female, light and dark, active and passive; was known in most of the primitive religious systems of both the old and new worlds. Thus, what resulted was the widespread, common veneration paid to the sexual parts, as they were associated to the productive and generative principles in nature. The origin of phallic worship is hidden behind so much obscurity that very little is actually known about it. The Phoenicians, Egyptians, Phrygians, Greeks, Hindus, and many others have legends and myths concerning phallic worship that date back to prehistory. This book explores the origins of phallic worship, its influence on the religions of antiquity, serpent symbolism, the tree of knowledge, the "fall of man", and sun-god worship in antiquity. The intricate correlations that Ancient Symbol Worship makes concerning the origin of phallic worship throughout the ancient world includes important knowledge which would otherwise not be known today.
