Biography[]
Nannia Colonna was the famously beautiful wife of Fabrizio Colonna, and she entered into an extramarital affair with Juan Borgia the Younger, the son of Cardinal Rodrigo Borgia. In 1492, Fabrizio caught the two fornicating one morning, and he beat Borgia in the face with his club, wounding him; Borgia escaped through the window. He then proceeded to beat Nannia to death with his club, leading to the Borgias avenging her by beating Marcantonio Colonna senseless.
