Serse (Xerxes, HWV40) is an opera seria by George Frideric Handel. The libretto is adapted by an unknown hand from that by Silvio Stampiglia for an earlier opera of the same name by Giovanni Bononcini. Stampiglia's libretto was itself based on one by Nicolò Minato that was set by Francesco Cavalli in 1654.

Arminio (HWV 36) is an opera composed by Georg Friedrich Händel.
Together with Giustino and Berenice, Arminio is one of three operas Händel wrote within a period of half a year in 1736. He began with the composition of Giustino on August 14 1736, followed by that of Arminio on 15. September. Having finished Arminio he resumed work on Giustino, which he finished on 20 October. In Mid-December, he went on to compose Berenice.
Arminio was performed for the first time at the Covent Garden Theatre on 12 January 1737, earlier than Giustino. It only saw five performances, the last one on 12th February.
The first modern performance took place on 23 February 1935 in Leipzig in a German language version by Max Seiffert and Hans Joachim Moser.

Arianna in Creta (Ariadne in Crete) (HWV 32) is an opera seria in three acts by George Frideric Handel. The Italian-language libretto was adapted from Pietro Pariati's Arianna e Teseo.

Sosarme, re di Media (Sosarmes, King of Media) is an opera by George Frideric Handel. Composed in 1732, the original setting of Portugal was changed to Sardis in Lydia. It was revived in 1734 with arias from Riccardo Primo. The first revival since 1734 was in 1970 at Abingdon, UK.[1]

Lotario (Lothair) (HWV 26) is an opera seria in three acts by George Frideric Handel. The Italian-language libretto was adapted from Antonio Salvi's Adelaide. The opera was first given at the King's Theatre in London on 2 December 1729. Paolo Rolli commented in a letter at the time to Giuseppe Riva that "everyone thinks it a very bad opera".[1] There were 10 performances, but it was not repeated. Handel later reused pieces in later operas. The first modern production was by Unicorn Theatre at the Kenton Theatre, Henley on Thames, 3 September 1975.

Partenope is an opera by George Frideric Handel composed in 1730. It was Handel's first comic opera which broke away from the Opera Seria tradition. The Royal Academy of Music rejected the work because of its frivolous nature, with relatively few extended arias and more recitative.

Tolomeo, re di Egitto (Ptolemy, King of Egypt) (HWV 25) is an opera in three acts by George Frideric Handel to an Italian text by Nicola Francesco Haym, adapted from Carlo Sigismondo Capece's Tolomeo et Alessandro. It was Handel's 13th and last opera for the Royal Academy of Music. It was first performed at the King's Theatre, London on 30 April 1728 and revived with revisions on 19 May 1730 and 2 January 1733. The first modern production was by Fritz Lehmann at Göttingen on 19 June 1938.

Siroe, re di Persia (or 'Siroes, King of Persia') is an opera in three acts by George Frideric Handel. The Italian-language libretto was by Nicola Francesco Haym, after Pietro Metastasio's Siroe. Like all of Metastasio's libretti, it was also set by Handel's contemporaries, ex. Leonardo Vinci, Antonio Vivaldi and Johann Adolf Hasse. It was Handel's 12th opera for the Royal Academy of Music. It was written for the sopranos Francesca Cuzzoni and Faustina Bordoni.

Riccardo Primo re d’Inghilterra (or 'Richard the First, King of England') is an opera in three acts by George Frideric Handel. The Italian-language libretto was by Paolo Antonio Rolli, after Francesco Briani's Isacio tiranno, set by Antonio Lotti in 1710. Handel wrote the work for the Royal Academy's 1726-1727 opera season, and also as homage to the newly crowned George II and the nation where Handel had just received citizenship.

Admeto, re di Tessaglia (Admetus, King of Thessaly) is a three-act opera with music composed by George Frideric Handel to an Italian-language libretto prepared by Nicola Haym. The story is partly based on Euripedes' Alcestis. The opera's first performance was at the Haymarket Theatre in London on 31 January 1727. The original cast included Faustina Bordoni as Alcestis and Francesca Cuzzoni as Antigona, as Admeto was the second of the five operas that Handel composed to feature specifically these two prime donne of the day. The opera received 19 performances in its first season, and over the time from September 1727 to January 1732, received 16 additional performances. Admeto was revived in 1754 and received 5 additional performances. The last, 6 April 1754, proved to be the last opera performance that Handel saw of his own operas in his lifetime.

Acis and Galatea (HWV 49) was originally a masque composed by George Frideric Handel. He first composed this piece while he was living at Cannons (the seat of James Brydges, 1st Duke of Chandos) during the summer of 1718. It is set to a libretto by John Gay, Alexander Pope, and John Hughes, who borrowed freely from John Dryden's English translation of Ovid published in 1717, The Story of Acis, Polyphemus and Galatea. In 1732 Handel revised and expanded it to three acts and presented the work in London as an ode.

Il pastor fido is an opera in three acts by George Frideric Handel. It was set to a libretto by Giacomo Rossi based on the famed and widely familiar pastoral poem of the same name by Giovanni Battista Guarini.
It was composed in 1712 and first performed in the same year. The opera opened to a largely hostile reception, probably due to disappointment after the success of Rinaldo: one diarist noted critically that "the scene represented only the Country of Arcadia; the Habits [costumes] were old – the Opera short". The roles of Mirtillo and Silvio were originally sung by the castratos Valeriano Pellegrini and Valentino Urbani. The overture is in six movements and is long for its time: it is thought that it may have been originally composed as an unrelated orchestral suite.
