Piccarda: Moon, Paradiso 2-5   Piccarda is the sister of Forese Donati, Dante's Florentine friend expiating the vice of gluttony in purgatory, and the wicked Corso Donati, who (according to Forese in Purgatory) will suffer eternal damnation in hell (Purg. 24.82-7). As a leader of the black guelphs, Corso is one of the political enemies responsible for Dante's exile from Florence. Forese also told Dante that Piccarda resides in Paradise. Members of the Donati family, Piccarda and her brothers are related to Dante through his marriage to Gemma Donati. The lunar sphere is assigned to those who for one reason or another did not maintain their religious vows. Piccarda belonged to the "Poor Clares," an order founded by St. Clare of Assisi (1194-1253), a follower of St. Francis. Corso forced Piccarda to leave the convent of Santa Chiara at Monticelli (near Florence) and marry his henchman, Rossellino della Tosa, for self-serving political reasons. She died soon after this marriage.
