MARTIN, a translator and dramatic author, was formerly an officer in the army, bearing the commission of a lieutenant-colonel in Queen Anne's reign, under the great duke of Marlborough, to whom he dedicated a translation of Caesar's Commentaries, which he had completed, and which is to this day a book held in good estimation. In 1714, he was made one of the Lords Commissioners of Trade and Plantations; and in 1717 was appointed envoy extraordinary to the court of Spain, in the room of —— Brett, Esq. but declined it, choosing rather to keep the post he already had, which was worth 1000l. per annum, and which he never parted with till his death, which was in May 1746. He was also many years member of parliament for the town of Portsmouth. He wrote two dramatic pieces; both of which (for the one is only a masque introduced in the third act of the other) were printed in the year 1705, without the author's consent. Their names are, 1. Orpheus and Euridice, a masque. 2. Solon, a tragic-comedy.
