Abbo Abbot of Fleury, in France, born 958, slain in a tumult at Reole, in Gascony, Nov. 13, 1004. He presided two years (985-987) over a monastic school in England, and returned to Fleury, where he was made abbot. He was so celebrated for his wisdom and virtues that people, even in far- distant parts, had recourse to him for advice and assistance, especially in all questions relating to monastic discipline, his zeal for which caused the tumult in which he was slain. — Neander, Ch.
