And the occasion of this startling unfolding of the poetic gift, of this passage of a soft and dreamy boy, into the keenest, boldest, sternest of poets, the free and mighty leader of European song, was, what is not ordinarily held to be a source of poetical inspiration,--the political life. The boy had sensibility, high aspirations, and a versatile and passionate nature; the student added to this energy, various learning, gifts of language, and noble ideas on the capacities and ends of man. But it was the factions of Florence which made Dante a great poet. But for them, he might have been a modern critic and essayist born before his time, and have held a high place among the writers of fugitive verses; in Italy, a graceful but trifling and idle tribe, often casting a deep and beautiful thought into a mould of expressive diction, but oftener toying with a foolish and glittering conceit, and whose languid genius was exhausted by a sonnet. He might have thrown into the shade the Guidos and Cinos of his day, to be eclipsed by Petrarch. But he learned in the bitter feuds of Italy not to trifle; they opened to his view, and he had an eye to see, the true springs and abysses of this mortal life--motives and passions stronger than lovers' sentiments, evils beyond the consolations of Boethius and Cicero; and from that fiery trial which without searing his heart, annealed his strength and purpose, he drew that great gift and power, by which he stands pre-eminent even among his high compeers, the gift of being real. And the idea of the _Commedia_ took shape, and expanded into its endless forms of terror and beauty, not under the roof-tree of the literary citizen, but when the exile had been driven out to the highways of the world, to study nature on the sea or by the river or on the mountain track, and to study men in the courts of Verona and Ravenna, and in the schools of Bologna and Paris--perhaps of Oxford.
