Berenice (HWV 38) is an opera in three acts by George Frideric Handel to an Italian libretto, written in Italy in 1709 and originally entitled Berenice, regina d'Egitto (Berenice, Queen of Egypt), by Antonio Salvi.
It was first performed at the Covent Garden Theatre in London, on 18 May 1737. It was not successful and was only performed four times.
The opera is based upon the life of Cleopatra (Berenice III of Egypt), daughter of Ptolemy IX (the main character in Handel's opera Tolomeo) and is set circa 81 BC.
The German-born Handel, after spending some of his early career composing operas and other pieces in Italy, settled in London, where in 1711 he had brought Italian opera for the first time with his opera Rinaldo. An enormous success, Rinaldo created a craze in London for Italian opera seria, a form focused overwhelmingly on solo arias for the star virtuoso singers.
Handel had presented new operas in London for years with great success. One of the major attractions in Handel's operas was the star castrato Senesino, whose relationship with the composer was often stormy and who eventually left Handel's company to appear with the rival Opera of the Nobility, set up in 1733. Handel moved to a different theatre, Covent Garden, and engaged different singers, but there were neither sufficient audience for opera in London nor aristocratic supporters to back two opera houses at once, and both opera companies found themselves in difficulty. None of Handel's three new operas in the 1736-37 season repeated the success of his earlier works, and he suffered a breakdown in his health, as reported by his friend Lord Shaftesbury:
