MARTIN, a translator and dramatic author, was originally an officer in the army, and bore the commission of lieutenant-colonel in Queen Anne's reign, under John duke of Marlborough, to whom he dedicated a translation of Caesar's Commentaries. In 1714 he was made one of the lords commissioners of trade and plantations; and in 1717 he was named envoy extraordinary to the court of Spain, but declined the appointment, rather choosing to keep the post he already had, which was worth L1,000 a year, and which he never parted with till his death, in May 1746. He was also many years member of parliament for the town of Portsmouth. He wrote two dramatic pieces, both of which were printed in the year 1705, without the author's consent. The names of these are, 1. Orpheus and Eurydice, a masque; 2. Solon, a tragi-comedy.
