Sir Thomas Herbert, who was related to William, earl of Pembroke, was sent by that nobleman, in 1626, to travel into Africa, Asia, &c. His noble patron dying suddenly soon after his return, he again went abroad; during which time the civil wars commenced, and Mr. Herbert, on his return from his second travels, adhered to the side of the parliament; and was, through the interest of Philip, earl of Pembroke, appointed one of the commissioners of parliament, and sent by them to the king at Newcastle. On the dismissal of his majesty's servants, Mr. Herbert was chosen by the king as groom of the bed-chamber, and was employed by his royal highness on several confidential services, which he performed to the entire satisfaction of the king, whom he constantly attended till his execution in 1648. He was for his faithful services by Charles II. advanced to the honour of knighthood July 3, 1660, and died 1681.
He published his Travels into Africa, Asia, &c. and also left in manuscript, Memoirs of the Two last Years of the Reign of King Charles I.; a new edition of which was published by Messrs. Nichol, Pall-mall, 1813; to which is prefixed his portrait.
