He found great alterations in this city. King Robert was dead. His daughter Jane succeeded to him: her dissentions with her husband produced a violent party spirit among the courtiers, while the pursuit of pleasure was the order of the day. A Court of Love, in imitation of those held in Provence, was instituted, over which the lady Mary presided. The lovers continued fondly attached to each other, though jealousies and trifling quarrels somewhat diversified the otherwise even course of their loves. The lady passed several months each summer at Baiæ, amidst a society given up to amusement, and to the indulgence of the greatest libertinism. From some unknown cause, Boccaccio did not accompany her on these occasions, and he was tormented by a thousand doubts, fearing that the dissolute manners of the court would corrupt her, whom he calls a mirror of chaste love, and injure her faith towards him. During one of these absences he wrote his poem of "Filostrato," on the subject of Troilus and Cressida, which he dedicated as a kind of peace-offering to his lady. He wrote also the "Amorosa Fiammetta," which is her fancied complaint, while he was at Florence, and the "Amorosa Visione," or Vision of Love; which is more poetic in its diction than any of his previous works in verse, though it labours under the disadvantage of being an acrostic; the initial letters of each verse forming a series of sonnets and canzoni, addressed in the same initials to "Madonna Maria."
