The snake is one of humankind's most powerful and ambiguous symbols: it has at various times represented immortality and death, male and female, deity and demon, circle and line, killer and healer, the highest wisdom and the deepest subconscious. By virtue of its mysterious movement, potent poison, fearful grip, unblinking gaze and lightning quick strike, the power and image of the snake has wound its way into every culture. Whether snakes are worshipped as gods, feared as devils, or handled in religious ceremonies to test faith, snakes have played a critical role in the human heritage. This book explores the cult of the snake in world history, religion, and folklore.
