Visione, the Teseide, and the Filostrato; and in L'Amorosa Fiammetta he wove out of their relations a romance in which her lover, who is there called Pamfilo, plays Aeneas to her Dido, though with somewhat less tragic consequences. The Proem to the Decameron shews us the after-glow of his passion; the lady herself appears as one of the "honourable company," and her portrait, as in the act of receiving the laurel wreath at the close of the Fourth Day, is a masterpiece of tender and delicate delineation. Boccaccio appears to have been recalled to Florence by his father in 1341; and it was probably in that year that he wrote L'Amorosa Fiammetta and the allegorical prose pastoral (with songs interspersed) which he entitled Ameto, and in which Fiammetta masquerades in green as one of the nymphs. The Amorosa Visione, written about the same time, is not only an allegory but an acrostic, the initial letters of its fifteen hundred triplets composing two sonnets and a ballade in honour of Fiammetta, whom he here for once ventures to call by her true name. Later came the Teseide, or romance of Palamon and Arcite, the first extant rendering of the story, in twelve books, and the Filostrato, nine books of the loves and woes of Troilus and Cressida. Both these poems are in ottava rima, a metre which, if Boccaccio did not invent it, he was the first to apply to such a purpose. Both works were dedicated to Fiammetta. A graceful idyll in the same metre, Ninfale Fiesolano, was written later, probably at Naples in 1345. King Robert was then dead, but Boccaccio enjoyed the favour of Queen Joan, of somewhat doubtful memory, at whose instance he hints in one of his later letters that he wrote the Decameron. Without impugning Boccaccio's veracity we can hardly but think that the Decameron would have seen the light, though Queen Joan had withheld her encouragement. He had probably been long meditating it, and gathering materials for it, and we may well suppose that the outbreak of the plague in 1348, by furnishing him with a sombre background to heighten the effect of his motley pageant, had far more to do with accelerating the composition than aught that Queen Joan may have said.
