The next six years he passed at the castle of Vico Nuovo, in Piedmont, as a guest of the Della Rovere, at first dividing his time between military expeditions in the summer, and study, chiefly of medicine and natural history, in the winter, until a severe attack of rheumatic gout brought his military career to a close. Henceforth his life was wholly devoted to study. In 1525 he accompanied Antonio della Rovera, bishop of Agen, to that city as his physician.
