Joseph Mallord William Turner (1785-1851) was a British Romantic, landscape painter, water colorist, and printmaker. It is said that his style lay the foundation for the movement known as Impressionism. His paintings number in the thousands. Among his best-known works are A Ship Aground, The Fighting Temeraire, Arth from the Lake of Zug, and Lausanne. This oil painting, titled Tivoli, shows an imaginative classical landscape that was probably painted as a pendant to the "Arch of Constantine, Rome." It has been suggested that the phantom figures are Tobit and the Angel (according to the Book of Tobit, God sent the angel Raphael disguised as a human to heal Tobit of his blindness and to free Sarah from the demon Asmodeus). The setting suggests the scenery of Tivoli, but when Turner's imagination was fired, he cared little about topographical or historical accuracy.
