What is "luxovius"

In Gallo-Roman religion, Luxovios, Latinized as Luxovius was the god of the waters of Luxeuil, worshipped in Gaul. He was a consort of Bricta. The thermal spring sanctuary at Lexeuil produced evidence of the worship of other deities, including the sky-horseman who bears a solar wheel, and Sirona, another deity associated with healing springs.
