Joanna appeared before the Papal Commission. She pleaded guilty only to having disliked her husband, and claimed that this was due to witchcraft. She was acquitted as innocent of all charges brought against her; and as the Pope was regarded as infallible judge, in morals as in matters of faith, the world was constrained to acquiesce in the judgment. Joanna returned to Naples, where she held a gay, voluptuous court, frequented by the wits and artists of Italy. Boccaccio wrote for her his filthy tales, which he afterwards grouped together in the _Decameron_. Petrarch corresponded with her. Leonardo da Vinci painted her portrait; pupils of Giotto painted for her; Troubadours sang before her, and were fulsome in their praise. But her rule was no rule at all. The country suffered from misgovernment. Companies of adventurers ravaged the kingdom, and carried their depredations to the very gates of Naples. Joanna cared for none of these things; did not give over her revelries and carnival entertainments. Her husband Louis was offended at her shameless gallantries, and beat her with his fists. He died in May, 1362; and she at once offered her hand to James of the House of Aragon, claimant to the throne of Majorca, a young and chivalrous prince. He accepted, and they were married in 1363; but she would not allow him any further title than that of Duke of Calabria. He was disgusted with the frivolity of her Court, and with her conduct, and fearing lest the same fate should befall him that had come on her first husband Andrew, he quitted Naples and fled to Spain. James of Aragon died, and in 1376 Joanna married Otto of Brunswick. This fourth marriage offended Charles of Durazzo, grandson of John de Gravia, younger brother of Robert, King of the Two Sicilies, who calculated on succeeding to the throne and the county of Provence should Joanna die childless. His father Louis had been poisoned by Queen Joanna. Now ensued the great schism.
