The typical icon of Jagannath is unlike other deities found in Hinduism who are predominantly anthropomorphic. However, aniconic forms of Hindu deities are not uncommon. For example, Shiva is often represented in the form of a Shiva linga. In most Jagannath temples in the eastern states of India, and all his major temples such as the Puri, Odisha, Jagannath is included with his brother Balabhadra and sister Subhadra. Apart from the principal companion deities, Jagannath icon shows a Sudarshana Chakra and sometimes under the umbrella cover of multiheaded Sesha Naga, both linking him to Vishnu. He was one of the introduction to Hinduism to early European explorers and merchants who sailed into Calcutta and ports of the Bay of Bengal. The Italian Odoric of Pordenone who was a Franciscan friar, visited his temple and procession in 1321 CE, and described him in the language of the Church. William Burton, visited his temple at Puri in 1633, spelled him as Jagarnat and described him to be in a shape like a serpent, with seven hoods.
