Aigradus (Or Angradus),
a French prelate, was monk of Fontanelles, near Rouen, and flourished about 699. He received his monastic institution under St.Lantbert, and became archbishop of Lyons in 678. At the request of St. Hilbert (q.v.) he wrote the Life of St. Ansbert, who ruled the monastery of St. Vaudrille from 678 to 695. The compilers of Gallia Christiana .(xi, 167) and modern authors attribute to Aigradus the fragment of the Life of St. Lantbert (or Lambert), edited as anonymous by Mabillon, Aeta Ord. Bened. III, ii, 462-465. See Henschen, Commentary, Acta SS. Boll. Feb. ii, '343; Histoire Lit. de la France, iv, 33-35, 57.
