Orlando is an opera seria in three acts by George Frideric Handel written for the King's Theatre in London in 1733. The Italian libretto was adapted from Carlo Sigismondo Capece's L'Orlando after Ludovico Ariosto's Orlando Furioso, which was also the source of Handel's operas Alcina and Ariodante. More an artistic than a popular success at its first performances, Orlando is today recognised as a masterpiece.
