About Joanna of Gallura
Lived 1289 – 1339 (aged 49–50). Joanna of Gallura was a monarch.
Joanna of Gallura (..., c. 1291 – Florence, 1339), also known as Giovanna Visconti, was the last titular Judge (giudicessa) of Gallura. Joanna claimed her rights in Sardinia to no avail and eventually sold them to her relatives, the Visconti of Milan, who later sold them to the Crown of Aragon. She is mentioned passingly by Dante Alighieri in the Divine Comedy. Her father, a friend of Dante's, but consigned to Purgatory with the other negligent rulers, asks her to be reminded of him.
Biography
Early life The Visconti of Pisa were present in Pisa since at least since the tenth century and since then had produced a lineage of influential Pisan politicians. In 1205, Lamberto Visconti married Elena of Gallura and became the first Visconti to be the Judge of Gallura. He was succeeded, in order, by Ubaldo, Ubaldo II, John, and Ugolino Visconti.
Joanna was the daughter of Ugolino (also known as Nino) and Beatrice, daughter of Obizzo II d'Este. Upon Nino's death in 1296, Joanna became the last Judge of Gallura. She succeeded her father when she was a baby, though her succession was purely nominal. Not long after her father's death, the Republic of Pisa, affiliated with the Ghibellines, took most of her inheritance. Nino had been a notable Guelph leader who had served as podestà in Pisa until his exile in 1288, during which he aligned with known Pisan enemies Florence and Lucca and led a campaign against Pisa.
In 1296, Pope Boniface VIII assigned Joanna as a ward to Volterra, where she and her mother would live for a few years. In that time, Beatrice became engaged to a son of Alberto Scotto, lord of Piacenza. Galeazzo I Visconti of Milan, desperate for an alliance with the Este family, had been able to circumvent the engagement and instead married Beatrice in 1300. This marriage outraged the Torriani family. With the help of Scotto, they drove the Visconti out of Milan. Galeazzo would then live in Tuscany until his death, but Beatrice was able to eventually return to Milan.
Marriage Though Pisa had taken most of her inheritance, Joanna remained in possession of great political power because of her title as Judge of Gallura and her parents' noble lineages. In adolescence, her political position and her beauty drew many suitors whose families sought power in Sardinia.
Joanna's first suitor was the son of the Genoese noble Bernabò Doria; a marriage with him would have promoted the union of Genoa and Pisa against the Crown of Aragon. Then, a second option became the nephew of the Count of Donaratico, Tedice della Gherardesca; the possibility of his marriage to Joanna polarized the Pisans, causing civil conflict. Finally, the Tuscan Guelphs recommended that Joanna marry Corradino Malaspina, whose family already owned many valuable assets in Sardinia. Corradino's marriage with Joanna would only further expand their wealth and territory. James II of Aragon also had a stake in Joanna's hand for marriage, as he wanted her to marry an Aragonese nobleman because it would aid his plan of conquering Sardinia while minimizing military costs.
Despite their desperate clamor for Joanna, none of the above noblemen married her. In 1308, Joanna married Rizzardo IV da Camino, Count of Ceneda and Lord of Treviso. The exact details of the assassination are unclear. According to the Ottimo Commento, Cangrande della Scala may have been involved in the plan. According to Benvenuto da Imola, another early commentator of the Divine Comedy, Guecello, Rizzardo's brother, may have been coveting Rizzardo's power and also abetted his assassination. After Rizzardo's death, Guecello promptly took over the position of Lord of Treviso.
Interpretations Quinones argues that this canto, through the analogy of Beatrice as Eve and Joanna as Mary, exemplifies the dichotomies of sadness and hope that define the mood of Purgatorio, such as death and revival, and the fall and salvation of humankind.
Diaz writes on Dante's portrayal of Beatrice: he has Nino identify her only by the men she has been with, thus emphasizing the perceived immorality of a woman marrying again. The viper to which Nino alludes is the symbol for the Visconti family of Milan and the cock is the symbol for Nino's own Visconti family of Pisa and Sardinia. Nino asserts that the viper will "hardly ornament [Beatrice's] tomb as handsomely as the cock," as if Beatrice were only a body to be decorated. Diaz indicates that in this scene, Beatrice's remarriage is framed as a sign of her uncontrollable lust and apathy towards Nino, even though the marriage was politically motivated and it had already been four years after Nino's death.
