Risco, Manuel, a learned Spanish ecclesiastic of the Augustinian Order, was born at Haro about 1730, and died about the close of the century. He acquired such reputation for knowledge in ecclesiastical history that he was appointed by the king, Charles III, to continue the history of which Florez published 29 vols. 4to. To these he added six volumes, written with equal ability and liberality of sentiment. The work was entitled Espana Sagrada. See Chalmers, Biog. Dict. s.v.
