Lippa Ariosti

Filippa Ariosti, known as Lippa and called la Bella (died 27 November 1347), was the daughter of the Bolognese noble Iacopo Ariosti. She met Obizzo III d'Este while he was exiled in Bologna after quarreling with Pope John XXII, and became his mistress; when he was reconciled with the papacy in 1329 she followed him to Ferrara. She bore him ten children, including Aldobrandino III and Niccolò II.

Obizzo married her on her deathbed, and a papal bull legitimated their children. Ariosto praised the beautiful Lippa of Bologna in Orlando Furioso.
