Litavis (also known as Litauis, Litaui, Litauia, and Llydaw) is a goddess in Celtic mythology worshiped by the ancient Gauls. Her name is found in inscriptions found at Aignay-le-Duc and M^alain of the C^ote-d'Or, France, where she is invoked along with the Gallo-Roman god Mars Cicolluis in a context which suggests that she might have been his consort. Also, a Latin dedicatory inscription from Narbonne (which was in the far south of Gaul), France, bears the words "MARTI CICOLLUI ET LITAVI" ("Mars Cicolluis and Litavis"). "Letavia" or "Letauia" may be derived from a Proto-Indo-European
