Agilmar (or Aimar), a French prelate, was bishop of Clermont in the 9th century. Driven from his diocese by the Normans, he took refuge in the county of Amaons, where' he brought the relics of Sts. Illis and Vincent. He deposited these in two grottos, which be-came the nucleus of large villages. In the Assembly of Pavia, Agilmar had a number of prelates who promised fidelity to Charles the Bald, and in 878 he sent, in: behalf of Louis the Stammerer, a letter to pope John VII, of which a long fragment may be found in Gallia Christiana, and in Acta Sanctorum, i, 13. He signed the acts of the Council of Mehun-on-the-Loire in 891. See Hoefer, Nouv. Biog. Generale, s.v.
