Question: What opera written by Henry Purcell starred Ludmila Vernerova?
Context: 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 Room is a concert and performance venue which forms part of the Southbank Centre, one of central London's leading cultural complexes.  It is named after the 17th century English composer Henry Purcell and has 370 seats.  The Purcell Room has hosted a wide range of chamber music, jazz, mime and poetry recitals.  In the context of the Southbank Centre it is the smallest of a set of three venues, the other two being the Royal Festival Hall, a large symphony hall, and the QEH, which is used for orchestral, chamber and contemporary amplified music. The Purcell Operatic Society was a short-lived but influential London opera company devoted to the production of stage works by Henry Purcell and his contemporaries.  It was founded in 1899 by the composer Martin Shaw and folded in 1902.  Its stage director and production designer was Gordon Craig whose productions for the company marked the beginning of his career as a theatre practitioner.  Their debut production of Purcell's opera "Dido and Aeneas" in 1900 was one of the earliest staged performances of the work in modern times. The Fairy-Queen (1692; Purcell catalogue number Z.629) is a masque or semi-opera by Henry Purcell; a "Restoration spectacular".  The libretto is an anonymous adaptation of William Shakespeare's wedding comedy "A Midsummer Night's Dream".  First performed in 1692, "The Fairy-Queen" was composed three years before Purcell's death at the age of 35.  Following his death, the score was lost and only rediscovered early in the twentieth century. Ludmila Vernerová (born 1962) is a Czech operatic soprano and the niece of oboist Pavel Verner.  After graduating from the Academy of Performing Arts in Prague, she was a regular performer at the Prague Chamber Opera in the mid 1980s.  In 1987 she joined the Prague National Theatre where she performed for 12 years, Since 1999 she has been a member of the Prague State Opera.  Among the many roles she has created on stage are Angelica in "Orlando furioso", Belinda in "Dido and Aeneas", Countess Almaviva in "The Marriage of Figaro", Donna Anna in "Don Giovanni", Fiordiligi in "Così fan tutte", Isabella in "Robert le diable", Lucy in "The Beggar's Opera", Micaela in "Carmen", Musetta in "La bohème", Pamina in "The Magic Flute", and the title roles in "Alcina" and "Rodelinda". Franklin Bershir Zimmerman (born June 20, 1923) is an American musicologist and conductor who has published extensively in the field of Baroque music, and particularly on the English composer, Henry Purcell.  He is most known for his complete catalogue of Purcell's works, considered "one of the most crucial contributions to Purcell research".  Each work in the catalogue is given a "Z number" which derives from Zimmerman's surname. Edward Henry Purcell (died 1765), organist, printer, and music publisher, was the son of Edward Purcell, and grandson of the English Baroque master, Henry Purcell.  He was a chorister in the Chapel Royal in 1737.  Upon the death of his father in 1740, he succeeded him as organist of St Clement, Eastcheap. 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. John Blow (baptised 23 February 1649 – 1 October 1708) was an English Baroque composer and organist, appointed to Westminster Abbey in 1669.  His pupils included William Croft, Jeremiah Clarke and Henry Purcell.  In 1685 he was named a private musician to James II.  His only stage composition, "Venus and Adonis" (ca. 1680–1687), was thought to influence Henry Purcell's later opera "Dido and Aeneas".  In 1687 he became choirmaster at St Paul's Cathedral, where many of his pieces were performed.  In 1699 he was appointed to the newly created post of Composer to the Chapel Royal.
