'Another fresco of Raffaelle in the same apartment presents a very different company, Dante alone appearing in both. Surrounded by the muses of Greek mythology, under a thicket of myrtles, sits Apollo, with the sources of Castalia at his feet. On either side are grouped those on whom the spirit of Apollo descended, the classical and Renaissance poets, to whom the waters of Castalia come down, a river making glad this other city of God. In this fresco it is the classical tradition, the orthodoxy of taste, that Raffaelle commemorates.' (97)
