Shiva, perhaps the most ancient of the Indian deities, and the third of the Hindu Trinity -- one of the most widely worshipped and edified deity in the Hindu pantheon, is worshipped often in the form of the lingam, or phallus. Evidence of phallic worship in the India date back to prehistoric times. Stone Lingams with several varieties of stylized "heads", or the glans, are found to this date in many of the old temples, and in museums in India and abroad.
