The story of the opera is taken from Virgil's "Aeneid". It tells of the Trojan Aeneas' tragic love for Dido, the Queen of Carthage. The opera manuscript has been lost or destroyed. Research and performance rely on earliest printed copies. Some music is believed missing from these early copies. That music is composed afresh by modern composers in Purcell's style. Sometimes music Purcell composed about 1685 is inserted into the score to make up for the lack of the original music. "Dido and Aeneas" is Purcell's best known work.
