He is before all things a poetical painter, blending the charm of story and sentiment, the medium of the art of poetry, with the charm of line and colour, the medium of abstract painting. So he becomes the illustrator of Dante. In a few rare examples of the edition of 1481, the blank spaces left at the beginning of every canto, for the hand of the illuminator, have been filled, as far as the nineteenth canto of the _Inferno_, with impressions of engraved plates, seemingly by way of experiment, for in the copy in the Bodleian Library, one of the three impressions it contains has been printed upside down, and much awry, in the midst of the luxurious printed page. Giotto, and the followers of Giotto, with their almost childish religious aim, had not learned to put that weight of meaning into outward things--light, colour, everyday gesture, which the poetry of the _Divine Comedy_ involves, and before the fifteenth century Dante could hardly have found an illustrator. Botticelli's illustrations are crowded with incident, blending, with a naive carelessness of pictorial propriety, three phases of the same scene into one plate. The grotesques, so often a stumbling-block to painters, who forget that the words of a poet, which only feebly present an image to the mind, must be lowered in key when translated into visible form, make one regret that he has not rather chosen for illustration the more subdued imagery of the _Purgatorio_. Yet in the scene of those who "go down quick into hell", there is an inventive force about the fire taking hold on the upturned soles of the feet, which proves that the design is no mere translation of Dante's words, but a true painter's vision; while the scene of the Centaurs wins one at once, for, forgetful of the actual circumstances of their appearance, Botticelli has gone off with delight on the thought of the Centaurs themselves, bright, small creatures of the woodland, with arch baby faces and _mignon_ forms, drawing their tiny bows.
