began to compile this book, in reverence towards God and St. John, and commendation of our city of Florence."--_G. Vill._ viii. 36.] [Footnote 104: _Sacchetti_, Nov. 114.] Dante, by the _Divina Commedia_, was the restorer of seriousness in literature. He was so, by the magnitude and pretensions of his work, and by the earnestness of its spirit. He first broke through the prescription which had confined great works to the Latin, and the faithless prejudices which, in the language of society, could see powers fitted for no higher task than that of expressing, in curiously diversified forms, its most ordinary feelings. But he did much more. Literature was going astray in its tone, while growing in importance; the _Commedia_ checked it. The Provençal and Italian poetry was, with the exception of some pieces of political satire, almost exclusively amatory, in the most fantastic and affected fashion. In expression, it had not even the merit of being natural; in purpose it was trifling; in the spirit which it encouraged, it was something worse. Doubtless it brought a degree of refinement with it, but it was refinement purchased at a high price, by intellectual distortion, and moral insensibility. But this was not all. The brilliant age of Frederick II., for such it was, was deeply mined by religious unbelief. However strange this charge first sounds against the thirteenth century, no one can look at all closely into its history, at least in Italy, without seeing that the idea of infidelity--not heresy, but infidelity--was quite a familiar one; and that side by side with the theology of Aquinas and Bonaventura, there was working among those who influenced fashion and opinion, among the great men, and the men to whom learning was a profession, a spirit of scepticism and irreligion almost monstrous for its time, which found its countenance in Frederick's refined and enlightened court. The genius of the great doctors might have kept in safety the Latin Schools, but not the free and home thoughts which found utterance in the language of the people, if the solemn beauty of the Italian _Commedia_ had not seized on all minds. It would have been an evil thing for Italian, perhaps for European literature, if the siren tales of the _Decameron_ had been the first to occupy the ear with the charms of a new language.
