In 1798 appeared his translation of Tansillo’s “Nurse,” with a dedication to his wife; and in 1805 his “Life and Pontificate of Leo the Tenth”—the son of Lorenzo, and the Pope who saw the rise of the Reformation. Although this latter book brought its author more money, it was less favourably received than his “Life of Lorenzo,” mainly on account of his treatment of the Reformation. But apart from this it is less satisfactory as a historical work. His knowledge of the contemporary state of intellectual Europe was too limited to enable him to deal adequately with a subject of so wide a scope. Nevertheless the book had a large sale, in spite of, or possibly in consequence of, the fact that the Italian translation was placed in the “Index.” Shortly after the publication of his first great work Roscoe renounced his practice as an attorney. Having a competent fortune, he purchased Allerton Hall, a fine old Jacobean house in a beautiful situation on the banks of the Mersey. He now turned his attention to agriculture, set up a model farm near his estate, cultivated the friendship of Coke of Holkham, read papers on agricultural subjects to local societies, and worked at the reclamation of Chat Moss. He also set in order the affairs of a banking house in which his friend Clarke, who lived in Italy, was a partner, and he thereby became involved in its direction and management. But he had still leisure for literary pursuits. He had one of the largest and most valuable private libraries in the district, especially rich in Italian history and literature. He interested himself in typography and induced John M’Creery—a well-known printer of his day—to settle in Liverpool, where his works were printed. He was a generous lover of the fine arts, and has the credit of discovering the genius of John Gibson, the sculptor, originally an apprentice to a marble mason in Liverpool, whom he sent to Rome. Gibson executed for Roscoe a basso-rilievo in terra-cotta, now in the Walker Gallery in Liverpool, the patron in his turn making his _protégé_ free of the treasures of his library at Allerton Hall. It was in this way that Gibson first became acquainted with the designs of the great Italian masters. The acquaintance thus formed with the Roscoe family was continued in the case of Mrs. Sandbach, a granddaughter of the Italian historian, who possessed many of Gibson’s works, and was in frequent correspondence with him. Indeed most of the details of Gibson’s life were only to be gleaned from his letters to Mrs. Sandbach, who was a very accomplished woman of considerable literary ability.
