Touched suddenly and deeply by an ardent desire of cultivating poetry, he, on his return home, cast aside all thoughts of business, and eagerly gave himself up to the Muses. And thus, at nearly mature age, impelled by his own wishes only, excited and led by none, his father averse, and always vituperating literature, he, untaught by any, applied to the cultivation of his understanding, devoting himself to the study of such authors as he could comprehend, with the greatest avidity and delight.[61] His genius and fervour conjoined to facilitate his progress; and his father, become aware of the inutility of opposition, at length consented that he should follow his own inclinations, and gave him the necessary assistance. Another circumstance occurred not long after to confirm his predilection for literature, and to exalt it in his eyes. He was present when Petrarch was examined by Robert, king of Naples, previous to his coronation in the Capitol. [Sidenote: 1341. Ætat. 28.] King Robert was a philosopher, a physician, and an astrologer, but hitherto he had despised poetry, being only acquainted with some Sicilian rhymes, and a few of the compositions of the Troubadours. Petrarch, discovering the ignorance of his royal patron, took an opportunity, at the conclusion of his examination, to deliver an oration in praise of poetry, setting forth its magical beauty and its beneficent influence over the minds and manners of men; and so exalted his art, that the king said, in Boccaccio's hearing[62], that he had never before suspected that the foolish rind of verse enclosed matter so lofty and sublime; and declared that now, in his old age, he would learn to appreciate and understand it, asking Petrarch, as an honour which he coveted, to dedicate his poem of Africa to him. From this time the lover of Laura became the Magnus Apollo of the more youthful Boccaccio: he named him his guide and preceptor, and became, in process of time, his most intimate friend. The liberal tastes and generous patronage of king Robert drew to his court many of the most illustrious men of the age. Boccaccio was exceedingly desirous, from boyhood, of seeing men celebrated for learning[63], and he cultivated a friendship with many of those who lived at Naples. Under the Calabrian Barlaam he studied Greek. Barbato, the chancellor of the king, Dionisio Robertis, bishop of Monopoli, Paolo Perugini, royal librarian, Giovanni Barrili,--these were all his particular friends; conversing with whom, he cultivated the literary tastes to which he entirely devoted himself. An ardent love of poetry, and an assiduous cultivation of his imagination, made the study of his own nature and its impulses a principal subject of contemplation; and thus softening his heart, opened an easy entrance to the passion of love. He became attached to a lady of high rank at Naples, whom he has celebrated in many of his works.
