with about eight portraits of individuals, all but three from before about 1475. Botticelli often slightly exaggerates aspects of the features to increase the likeness. He also painted portraits in other works, as when he inserted a self-portrait and the Medici into his early Adoration of the Magi. Several figures in the Sistine Chapel frescos appear to be portraits, but the subjects are unknown, although fanciful guesses have been made. Large allegorical frescos from a villa show members of the Tornabuoni family together with gods and personifications; probably not all of these survive but ones with portraits of a young man with the Seven Liberal Arts and a young woman with Venus and the Three Graces are now in the Louvre. Dante, printing and manuscripts Botticelli had a lifelong interest in the great Florentine poet Dante Alighieri, which produced works in several media. He is attributed with an imagined portrait. According to Vasari, he "wrote a commentary on a portion of Dante", which is also referred to dismissively in another story in the Life, but no such text has survived. Botticelli's attempt to design the illustrations for a printed book was unprecedented for a leading painter, and though it seems to have been something of a flop, this was a role for artists that had an important future. Vasari wrote disapprovingly of the first printed Dante in 1481 with engravings by the goldsmith Baccio Baldini, engraved from drawings by Botticelli: "being of a sophistical turn of mind, he there wrote a commentary on a portion of Dante and illustrated the Inferno which he printed, spending much time over it, and this abstention from work led to serious disorders in his living." Vasari, who lived when printmaking had become far more important than in Botticelli's day, never takes it seriously, perhaps because his own paintings did not sell well in reproduction. The Divine Comedy consists of 100 cantos and the printed text left space for one engraving for each canto. However, only 19 illustrations were engraved, and most copies of the book have only the first two or three. The first two, and sometimes three, are usually printed on the book page, while the later ones are printed on separate sheets that are pasted into place. This suggests that the production of the engravings lagged behind the printing, and the later illustrations were pasted into the stock of printed and bound
