Dante does not belong in any strict sense to the history of the Revival of Learning. The 'Divine Comedy' closes the Middle Ages and preserves their spirit. It stands before the vestibule of modern literature like a solitary mountain at the entrance of a country rich in all varieties of landscape. In order to become acquainted with its grandeur, we must leave the fields and forests that we know, ascend the heights, and use ourselves to an austerer climate. In spite of this isolation, Dante's influence was powerful upon succeeding generations. The modern mind first found in him its scope, and recognised its freedom; first dared and did what placed it on a level with antiquity in art. Many ideas, moreover, destined to play an important part in the coming age, received from him their germinal expression. It may thus be truly said that Dante initiated the movement of the modern intellect in its entirety, though he did not lead the Revival considered as a separate moment in this evolution. That service was reserved for Petrarch. There are spots upon the central watershed of Europe where, in the stillness of a summer afternoon, the traveller may listen to the murmurs of two streams--the one hurrying down to form the Rhine, the other to contribute to the Danube or the Po. Born within hearing of each other's voices, and nourished by the self-same clouds that rest upon the crags around them, they are henceforth destined to an ever-widening separation. While the one sweeps onward to the Northern seas, the other will reach the shores of Italy or Greece and mingle with the Mediterranean. To these two streamlets we might compare Dante and Petrarch, both of whom sprang from Florence, both of whom were nurtured in the learning of the schools and in the lore of chivalrous love. Yet how different was their mission! Petrarch marks the rising of that great river of intellectual energy which flowed southward to recover the culture of the ancient world. The current of Dante's genius took the contrary direction. Borne upon its mighty flood, we visit the lands and cities of the Middle Ages, floating toward infinities divined and made the heritage of human nature by the mediæval spirit.
