Born in 1313, at seven years of age he showed signs of a literary facility, and his father, a merchant of Florence, put him to school with a reputable grammarian; but afterward, deciding to devote him to merchandise, sent him to study arithmetic,--restive and profitless in which, he was sent to study canon law, and finding his level no better there, went back to traffic and to Naples in his father's business when he was about twenty. The story runs that the sight of the tomb of Virgil turned his thoughts to poetry; but this confusion of the _post hoc_ with the _propter hoc_ is too common in remote and romantic legend to value much. The presence of Petrarch in the court of Robert, King of Naples, is far more likely to have been the kindling of his genius to its subsequent activity: and the passion he acquired while there for the illegitimate daughter of the King, Maria,--the Fiammetta of his later life,--furnished the fuel for its burning; his first work, the 'Filocopo,' being written as an offering to her. It is a prose love story, mixed with mythological allusions,--after the fashion of the day, which thought more of the classics than of nature; and like all his earlier works, prolix and pedantic. The 'Theseide,' a purely classic theme, the war of Theseus with the Amazons, is in verse; and was followed by the 'Ameto,' or 'Florentine Nymphs,' a story of the loves of Ameto, a rustic swain, with one of the nymphs of the valley of the Affrico, a stream which flows into the Arno not far from where the poet was born, or where at least he passed his youth; and to which valley he seems always greatly attached, putting there the scene of most of his work, including the 'Decameron.' 'Ameto' is a mythological fiction, in which the characters mingle recitations of verse with the prose narration, and in which the gods of Greece and Rome masque in the familiar scenes. Following these came the 'Amorosa Visione,' and 'Filostrato,' in verse; 'Fiammetta' in prose, being the imaginary complaint of his beloved at their separation; 'Nimfale Fiesolano,' in verse, the scene also laid on the Affrico; and then the 'Decameron,' begun in 1348 and finished in 1353, after which he seems to have gradually acquired a disgust for the world he had lived in as he had known it, and turned to more serious studies. He wrote a life of Dante, 'II Corbaccio,' a piece of satirical savagery, the 'Genealogy of the Gods,' and various minor works; and spent much of his time in intercourse with Petrarch, whose conversation and influence were of a different character from that of his earlier life.
