What is "anextiomarus"

Anextiomarus is a Celtic epithet of the sun-god Apollo recorded in a Romano-British inscription from South Shields, England. The form is a variant of Anextlomarus 'Great protector', a divine style or name attested in a fragmentary Gallo-Roman dedication from Le Mans, France. Anextlomarus is also attested as a Gaulish man's father's name at Langres, and a feminine divine form, Anextlomara, appears in two other Gallo-Roman dedications from Avenches, Switzerland.
