Borvo or Bormo (Gaulish: *Borwō, Bormō) was an ancient Celtic god of healing springs worshipped in Gaul and Gallaecia.[1][2] He was sometimes identified with the Graeco-Roman god Apollo, although his cult had preserved a high degree of autonomy during the Roman period.[3]
The GaulishtheonymBoruō means 'hot spring', 'warm source'. It stems from the Proto-Celtic verbal root *berw- ('boil, brew'; cf. Old Irishberbaid, Middle Welshberwi), itself from Proto-Indo-European *bʰerw- ('boil, brew'; cf. Latin ferueō 'to be intensely hot, boil', Sanskrit bhurváni 'agitated, wild').[4][5] The Bhearú river (River Barrow) in Ireland has also been linked to this Celtic root.[6]
The variant Bormō could have emerged from a difference in suffixes or from dissimilation.[4][2] Known derivates include Bormanicus (Caldas de Vizela), from an earlier *Borwānicos, and Bormanus or Borbanus (Aix-en-Diois, Aix-en-Provence), from an earlier *Borwānos.[7][8] A goddess named Boruoboendoa, perhaps reflecting the Gaulish theonym *Buruo-bouinduā or *Buruo-bō-uinduā, has also been found in Utrecht.[9]
Borvo was frequently associated with a divine consort, usually Damona (Bourbonne, Bourbon-Lancy), but sometimes also Bormana when he was worshipped by the name Bormanus (Die, Aix-en-Diois).[15][2] Bormana was in some areas worshipped independently of her male counterpart, such as at Saint-Vulbas.[16][2]

Borvo bore similarities to the goddess Sirona, who was also a healing deity associated with mineral springs.[17] According to some scholars, Sirona may have been his mother.[15]
