Orlando (RV 728), usually known in modern times as Orlando furioso (Italian pronunciation: [orˈlando fuˈrjoːzo]), is an opera in three acts by Antonio Vivaldi to an Italian libretto by Grazio Braccioli, based on Ludovico Ariosto's epic poem Orlando Furioso (The Frenzy of Orlando). The first performance of the opera was at the Teatro San Angelo, Venice, in November 1727. It is to be distinguished from an earlier Vivaldi opera of 1714, Orlando furioso, set to much the same libretto, once thought to be a revival of a 1713 opera by Giovanni Alberto Ristori but now considered by Vivaldian musicologists to be a fully-fledged opera by Vivaldi himself.
