ABBO (St.) M. (Nov. 13) (10th cent.) A French Benedictine monk of literary attainments rare in the age in which he lived, who was invited by St. Oswald of Worcester to preside over the community he had founded at Ramsey Abbey. After the death of St. Oswald St. Abbo returned to France and became Abbot of Fleury on the Loire. He afterwards conducted skilfully and successfully various negotiations between the Holy See and the King of France. He lost his life while endeavouring to stop a riot (a.d. 1004), and by his people was at once honoured as a Martyr.
