WALTER, the historian of Gustavus Adolphus, was born about the beginning of the eighteenth century. He was educated at Marlborough School, and afterwards at Oxford, where he graduated in 1720. He early enjoyed the friendship of Pope, who is said to have contributed largely to his Essay on Satire, 8vo., 1730; and to his Essay on Reason, fol. 1735. He afterwards became vice-principal of St Mary Hall, and, through the influence of Lord Chesterfield, to whose natural son he had been tutor from 1746 to 1750, canon of Windsor. In 1759 he published his History of Hartford Gustavus Adolphus, in two vols. 4to. This work, though devoid of order, and harsh and pedantic in style, yet exhibits great research and great ability. Harte, who is said to have been a man of excessive vanity, left London on the day of the publication of his book, that he might be out of the way of the great praise it was to receive; and he was ashamed to return when he found how very ill it had succeeded. His only other productions are some Sermons, and the Amaranth, a poem which, as he informs us, was written for his private consolation under a lingering and dangerous state of health, and which is marked by a very serious cast of feeling. He died at Bath in 1774.
