(Gregory the Monk) a Greek writer of the first part of the 10th century. Though always called "the monk," he was not such, as he did not live in a convent, but practiced an ascetic life at his own home. His spiritual guide was St. Basil the Younger, after whose death he wrote two memoirs of him, one of which survives in the Acta Sanctorum, March 3, 667. With many absurd stories, it gives a good deal of valuable historical matter. — Fabricius, Bibl. Graeca 10:206 Cave, Hist. Lit. anno 940; Hoefer, Nouv. Biog. Generale, 21:877.
