In 1785, William Jones drew a close comparison between a particular form of Ganesha, known as Dwimukhi-Ganesha, and Janus, the two-headed Roman god. Jones felt the resemblance between Dwimukhi-Ganesha and Janus was so strong that he referred to Ganesha as the "Janus of India." The Dwimukhi-Ganesha form is a very unusual depiction in which Ganesha is shown with the head of an elephant looking toward his right and a human head at his left. It was possessed of four arms. Nagar says that the Dwimukhi-Ganesha form was associated with the region around Bombay.
