is an opera in a prologue and two acts composed by Luigi Dallapiccola to his own libretto based on the legend of Ulysses. It premiered at the Deutsche Oper Berlin (in German translation by Karl-Heinrich Kreith as Odysseus) on 29 September 1968 conducted by Lorin Maazel with Erik Saedén in the title role. Ulisse was Dallapiccola's only full-length last opera and took eight years to compose. As in his previous one-act operas, Volo di notte and Il prigioniero, his declared theme was "the struggle of man against some force much stronger than he".
