Luxovius

In Gallo-Roman religion, Luxovios, Latinized as Luxovius, was the god of the waters of Luxeuil, worshiped in Gaul. He was a consort of Bricta. The thermal spring sanctuary at Luxeuil provided evidence of the worship of other deities, including the sky-horseman who bears a solar wheel, and Sirona, another deity associated with healing springs.
Inscriptions.
Luxovius is recorded in the following two inscriptions, both from Luxeuil-les-Bains :
"To Lusso(v)ios and Bricta, Divixtius Constans freely and deservedly fulfilled his vow." (CIL 13, 05425)
"To Luxovios and Brixta, Gaius Julius Firmans freely and deservedly fulfilled his vow." 
Etymology.
The name Luxovios implies light symbolism. This may indicate that the god was a deity of both light and curative spring waters, two elements that were strongly linked in the Celtic world.
