The Chiaramonti Museum, housed in the loggia that connected the Palazzetto di Belvedere with the Vatican Palaces, takes its name from Pope Pius VII Chiaramonti. The criteria for the arrangement of the works were even dictated by Antonio Canova, who aimed to present the "three sister arts" together: sculpture, in the ancient works on display; architecture, in the brackets obtained from ancient architectural frames; and painting, in the frescoes. The latter were created by young artists of the time at the expense of Canova himself. Comprising about a thousand exhibits of ancient sculpture, the Chiaramonti Museum has one of the largest collections of Roman portraits, but is also rich in examples of ideal and funerary sculpture.
