La cena delle beffe (The Jesters' Supper) is an opera in four acts composed by Umberto Giordano to an Italian libretto by Sem Benelli adapted from his 1909 play of the same name. The story, set in Florence at the time of Lorenzo de' Medici, recounts the rivalry between Giannetto Malespini and Neri Chiaramantesi for the affections of the beautiful Ginevra and Giannetto's thirst for revenge over a cruel joke played on him by Neri and his brother Gabriello. Giannetto's revenge "joke" ultimately leads Neri to murder both Ginevra and (by mistake) his own brother. The opera ends with Neri's descent into madness.
