Paolo Giovio (also spelled Paulo Jovio; Latin: Paulus Jovius) was an Italian physician, historian and biographer, and prelate.
He is chiefly known as the author of a celebrated work of contemporary history, Historiarum sui temporis libri XLV, of a collection of lives of famous men, Vitae virorum illustrium (1549‑57), and of Elogia virorum bellica virtute illustrium, (Florence, 1554), which may be translated as Praise of Men Illustrious for Courage in War (1554). He is best remembered as a chronicler of the Italian Wars. His eyewitness accounts of many of the battles form one of the most significant primary sources for the period.
