The famous man-size lingam in the Parashurameshwar Temple in the Chitoor Distirct of the Indian State of Andhra Pradesh, better known as the Gudimallam Lingam, is about 1.5 metres in height, carved in polished black granite. Dated back to ca. 2300-2800 BC, it is one of the existing lingams from the pre-Buddhist period. The almost naturalistic giant lingam is distinguished by its prominent, bulbous head, and an anthropomorphic form of Shiva 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 a more leaning towards the naturalistic style, with the glans clearly indicated.
