The dates of the composition and first performance of the opera are uncertain . It was composed no later than July 1688, and had been performed at Josias Priest's girls' school in London by the end of 1689 . Some scholars argue for a date of composition as early as 1683 . The story is based on Book IV of Virgil's Aeneid . It recounts the love of Dido, Queen of Carthage, for the Trojan hero Aeneas, and her despair when he abandons her . A monumental work in Baroque opera, Dido and Aeneas is remembered as one of Purcell's foremost theatrical works . It was also Purcell's only true opera, as well as his only all - sung dramatic work . One of the earliest known English operas, it owes much to John Blow's Venus and Adonis, both in structure and in overall effect . The influence of Cavalli's opera Didone is also apparent . </P> <P> Before Dido and Aeneas, Purcell had composed music for several stage works, including nine pieces for Nathaniel Lee's Theodosius, or The Force of Love (1680) and eight songs for Thomas d'Urfey's A Fool's Preferment (1688). He also composed songs for two plays by Nahum Tate (later the librettist of Dido and Aeneas), The Sicilian Usurper (1680) and Cuckold - Haven (1685). Dido and Aeneas was Purcell's first (and only) all - sung opera and derives from the English masque tradition . </P>
