Dido and Aeneas (Z. 626) is an opera in a prologue and three acts, written by the English Baroque composer Henry Purcell with a libretto by Nahum Tate.
 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.

The Purcell Society, founded in 1876 (principally by William Hayman Cummings) is an organization dedicated to making the complete musical works of Henry Purcell available.
 Between 1876 and 1965, scores of all the known works of Purcell were published, in 32 volumes.
 Advances in musical scholarship and editorial techniques in the decades after the first volumes were issued meant that by the second half of the 20th century they were no longer meeting the needs of users.
 Beginning in the 1960s, the Purcell Society began to issue revised versions of the scores.
 The website gives details of the scores in the revised series that are currently available.
