The Neptunalia celebrates the divinity of the sea god, Neptune. His wife, Salacia, is goddess of the wide open, salty sea. Inland, she rules over springs of highly mineralized waters. The goddess Sulis, worshiped at the sacred hot springs at Bath, appears to be an aspect of Salacia. In the north, Neptune and Salacia are equivalent to the Norse god, Aegir, and his consort, Ran.
