Shiva, the most widely worshipped and edified male deity in the Hindu pantheon, is worshipped much more commonly in the form of the lingam, or the phallus. Evidence of the lingam in India dates 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. The famous man-size lingam in the Parashurameshwar Temple in Gudimallam, Chitoor District of Andhra Pradesh known as the Gudimallam Lingam, is about in height, carved in polished black granite. It is one of the existing lingams from the pre-Buddhist period. The almost naturalistic giant lingam is distinguished by its prominent, bulbous glans, and an anthropomorphic form of Parashurama carved in high relief on the shaft. Shiva Lingams in India have tended to become more and more stylized over the centuries, and existing lingams from before the 6th century show more leaning towards a naturalistic style, with the glans clearly indicated.
