The worship of the Sacre Bull was widespread in the ancient world. It is perhaps most familiar to the Western world in the Biblical episode wherein an idol of the Golden Calf is made by Aaron and worshipped by the Hebrews in the wilderness of Sinai (Exodus). Young bulls were set as frontier markers at Tel Dan and at Bethel the frontiers of the Kingdom of Israel. In other cultures, Marduk is the "bull of Utu" and the Hindu God Shiva's steed is Nandi, the Bull. Nandi the bull can be traced back to Indus Valley Civilization, where dairy farming was the most important occupations. The bull Nandi is Shiva's primary vehicle and is the principal gana(follower)of Shiva.
