The present book throws new light on the gradual development of the concept of Rudra-Siva in his animal, phallic and human forms, since the days of the Harappa Civilization. It examines how Siva, the composite Aryan-non-Aryan Divinity, was not only admitted but was ultimately crowned with an exalted position in the Brahmanical pantheon; how the bull once identified with the deity, was regulated to the position of a vahana; how phallism was related to Saivism and also how Siva, in his different forms, was represented in early Indian Art and the Art of Further India. The wide range and depth of the author's research fills a vital gap in the subject and his treatment of the entire subject is unique. This methodical study on Siva also contains an exhaustive bibliography.
