Cattle are prominent in some religions and mythologies. As such, numerous peoples throughout the world have at one point in time honored bulls as sacred. In the Sumerian religion, Marduk is the "bull of Utu". In Hinduism, Shiva's steed is Nandi, the Bull. The sacred bull survives in the constellation Taurus. The bull, whether lunar as in Mesopotamia or solar as in India, is the subject of various other cultural and religious incarnations as well as modern mentions in New Age cultures.

Ra or Re was the ancient Egyptian deity of the Sun. By the Fifth Dynasty, in the 25th and 24th centuries BC, he had become one of the most important gods in ancient Egyptian religion, identified primarily with the noon-day sun. Ra ruled in all parts of the created world: the sky, the Earth, and the underworld. He was believed to have ruled as the first pharaoh of Ancient Egypt. He was the god of the sun, order, kings and the sky.
