d. c.860. Scholar and controversialist. Nothing is known of his early life before he became a deacon of Lyons during the period when Agobard* was its bishop (816-40). After Agobard's deposition (he was later reinstated) in 835 because of his opposition to the schemes of Empress Judith, Florus defended the rights and independence of the Church of Gaul in De iniusta vexatione ecclesia Lugdonesis. His other writings included a defense of moderate predestination against the extreme views of Gottschalk, three treatises on liturgy, a commentary on the epistles of Paul, some additions to the Martyrology of Bede, and a collection of poems.
