Martin, Gregory an English Roman Catholic theologian of the 16th century, was a native of Sussex, and was admitted a scholar of St. John's College, Oxford, in 1557. He became professor of Hebrew at Douay, and subsequently at Rheims. He died in 1582. He is supposed to have been the author, or one of the authors, of the Rheims translation of the New Testament, and of the Old Testament in the Douay version. He wrote several theologico-controversial pamphlets, among them A Discovery of the manifold Corruptios of the Holy Scriptures by the Heretics of our Days, specially the L'English Sectaries (printed in Fulke's Defence of the Translations, Parker Society, 1843). — Allibone, Dict. of Brit. and Amer.
