In Celtic mythology, Borvo ("to boil"), also Bormo, Bormanus, was a deity worshipped in Gaul. He was associated with mineral springs, hot springs and healing. He was equated with Apollo in Roman times. His wife was Damona. He is son of Sirona, who, like his wife, is a goddess of cattle.
Damona was a Gaulish goddess known from a number of Burgundian inscriptions where she is generally partnered with Apollo and Borvo.
At Alise-Sainte-Reine she is associated with Apollo Moritasgus, at Bourbonne-les-Baines she is associated with Apollo and Borvo, whereas at Bourbon-Lancy she is associated with Borvo and Bormo.
Both Apollo and Borvo are associated with healing spring sanctuaries and Damona may have been the goddess of the waters.
