The frescoes on the walls are from the deserted palace Magliana, the hunting-seat of Leo X., which has long been utilized as a farm by a community of nuns, and only inhabited by labourers. The frescoes are all more or less injured, and the feet of each figure, together with the lower part of the pictures, are quite obliterated. They represent the Muses, with Apollo as Musagetes, each figure distinguished by a motto in verse descriptive of the individual character, from the epigrams of Ausonius, and consist of the figures of Polyhymnia; Urania, with a distant view of Florence in the background (perhaps allusive to the pre-eminence of that city in astronomical science); Thalia, with the motto, "Comica lasciva gaudet sermone Thalia;" Clio, who is playing on the double flute; and Apollo, as leader of the Nine, who is seated, and playing on the violin: in the background of this picture is introduced a small group of Perseus slaying Medusa, while Pegasus springs from the blood of the decapitated gorgon. All these frescoes are ascribed to Giovanni lo Spagna, and there is much in their conception and sentiment which reminds us of the far superior works by that pupil of Pietro Perugino.
