Odilon a French monastic, flourished in the opening of the 10th century. He died about 920. All that is known of the circumstances of his life is that he had intimate relations with Huebald of Saint-Amand and Ingranne, dean of Saint-Medard, who was created bishop of Laon in 932. The writings of Odilon are, a recital of the removal of the bodies of St. Sebastian and St. Gregory the Great from Rome to Saint-Medard de Soissons, published by Bollandus and Mabillon, Acta Sanect. Ord. S. Bened. v. 383: — another history, of the removal of the relics of St. Marcellin, St. Peter the exorcist, and others, in the same volume of the Acta, p. 411: — a letter to Huebald, given to the public by Maartene, Anpliss. Collect. vol. 1. The authors of the hist. litteraire speak of some other works, but they are attributed to the monk Odilon only by simple conjecture. See Hist. litter. de la France, 6:173.
