Atepomarus[1] or Atepomaros[2] in Celtic Gaul was a healing god from Mauvières (Indre).
[3] Scholarship suggests the name is a compound of at- (intensifier), -epo- (the Celtic word for "horse") and -marus ("large, great").
[8][9] Pierre-Yves Lambert rejects his connection with horses and suggests an etymology based on *ad-tepo, related to 'protection, refuge'.
[10] A character named Atepomarus appears with a Momoros (fr) as a pair of Celtic kings and founders of Lugdunum.
[8][13] An inscription of Apollo Atepomarus was found in Mauvières, tied to the Gallic tribe of the Bituriges.
