Of the poems written in his youth he made a selection, and with a commentary gave them to the world as his first work.[38] All the sonnets and canzoni contained in it bear more or less directly on his love for Beatrice Portinari. This lady, whose name is so indissolubly associated with that of Dante, was the daughter of a rich citizen of good family. When Dante saw her first he was a child of nine, and she a few months younger. It would seem fabulous, he says, if he related what things he did, and of what a passion he was the victim during his boyhood. He seized opportunities of beholding her, but for long never passed beyond a silent worship; and he was eighteen before she spoke to him, and then only in the way of a passing salutation. On this he had a vision, and that inspired him with a sonnet, certainly not the first he had written, but the first he put into circulation. The mode of publication he adopted was the common one of sending copies of it to such other poets as were within reach. The sonnet in itself contains a challenge to interpret his dream. Several poets attempted the riddle--among them the philosopher and poet Guido Cavalcanti. They all failed in the solution; but with some of them he was thus brought into terms of intimacy, and with Cavalcanti of the closest friendship. Some new grace of style in Dante's verse, some art in the presentation of his mystical meaning that escapes the modern reader, may have revealed to the middle-aged man of letters that a new genius had arisen. It was by Guido's advice that the poems of which this sonnet stands the first were some years later collected and published with the explanatory narrative. To him, in a sense, the whole work is addressed; and it agreed with his taste, as well as Dante's own, that it should contain nothing but what was written in the vulgar tongue. Others besides Guido must have recognised in the little book, as it passed from hand to hand, the masterpiece of Italian prose, as well as of Italian verse. In the simple title of _Vita Nuova_, or _The New Life_,[39] we can fancy that a claim is laid to originality of both subject and treatment. Through the body of the work, though not so clearly as in the _Comedy_, there rings the note of assurance of safety from present neglect and future oblivion.
