Artaserse is an opera in three acts by the Czech composer Josef Mysliveček, set to a popular libretto by Metastasio that was originally performed in 1730. It was customary to alter the Metastasian text considerably for operas in the 1770s, but this one mainly adheres to the original Metastasian text, albeit with the placement of some scenes re-arranged and some scenes omitted. All of Mysliveček's operas are of the serious type in Italian referred to as opera seria.

L'assedio di Calais is an 1836 melodramma lirico, or opera, in three acts by Gaetano Donizetti, his 49th opera. Salvatore Cammarano wrote the Italian libretto, which has been described as "...a remarkable libretto, the closest Cammarano ever got to real poetry, particularly in his description of the embattled city and the heartfelt pride of its citizens". It was based on Luigi Marchionni's play L'assedio di Calais, which had been presented in Naples around 1825, and secondarily on Luigi Henry's ballet L'assedio di Calais, which had been performed in Naples in 1828 and revived in 1835.

Il Bellerofonte is an 18th-century Italian opera in three acts by the Czech composer Josef Mysliveček. It conforms to the serious type that was typically set in the distant past. The libretto, based on the Greek legend of Bellerophon, was written by Giuseppe Bonecchi. The work was dedicated to King Ferdinand I of the Two Sicilies and was first performed at the Teatro San Carlo in Naples on 20 January 1767, the birthday of his father, King Charles III of Spain. The cast featured two stellar singers of the time, Caterina Gabrielli and Anton Raaff, in the leading roles. The opera was only the composer's second one, and the first that permitted him the opportunity to write music for first-rate vocal artists. The production was highly successful, indeed responsible for a meteoric rise in his reputation as an operatic composer. From the time of the premiere of Bellerofonte until his death in 1781, Mysliveček succeeded in having more new opere serie brought into production than any other composer in Europe. During the same time span, he also had more new operas staged at the Teatro San Carlo in Naples than any other composer.

La Calliroe is an opera in three acts by Josef Mysliveček set to a libretto by Matteo Verazi that is based on Greek legends about the Oceanid Callirrhoe.

Demetrio is an eighteenth-century Italian opera in 3 acts by the Czech composer Josef Mysliveček. It was the composer's second setting of a libretto by the Italian poet Metastasio that was first performed in 1731, one of the most popular of the Metastasian librettos in Mysliveček's day. For a performance in the 1770s, it would only be expected that a libretto of such age would be abbreviated and altered to suit contemporary operatic taste. The cuts and changes in the text made for the 1779 performance of Mysliveček's opera are not attributable. All of Mysliveček's operas are of the serious type in Italian language referred to as opera seria.

Demofoonte is an opera in three acts by the Czech composer Josef Mysliveček. It was the composer's second setting of this popular libretto by Metastasio first produced in 1733.

All of Mysliveček's operas are of the serious type in Italian referred to as opera seria.

Elvida is a melodramma or opera in one act by Gaetano Donizetti. Giovanni Schmidt wrote the Italian libretto. The opera was written as a pièce d'occasion for the birthday of Queen Maria of the Two Sicilies. The choice of subject matter was no doubt intended as an elegant acknowledgement of the Queen's Spanish ancestry. Donizetti received little financial reward for the work and, as a result, put the minimum of effort into its composition.

Ezio is an eighteenth-century Italian opera in 3 acts by the Czech composer Josef Mysliveček. It was the composer's first setting of a libretto by the Italian poet Metastasio that was first performed with music by Pietro Auletta in 1728, one of the most popular of the Metastasian librettos in Mysliveček's day. The story is based on incidents from the lives of the 5th-century Roman emperor Valentinian III and his general Aetius. For a performance in the 1770s, it would only be expected that a libretto of such age would be abbreviated and altered to suit contemporary operatic taste. The cuts and changes in the text made for the 1775 performance of Mysliveček's opera are not attributable. All of Mysliveček's operas are of the serious type in Italian language referred to as opera seria.

Farnace is an 18th-century Italian opera in 3 acts by the Czech composer Josef Mysliveček. It was composed to a libretto by the Italian poet Antonio Maria Lucchini that is best known from a setting by Antonio Vivaldi first produced at the Teatro Sant'Angelo in Venice for the carnival operatic season of 1727. For a performance in the 1760s, it would only be expected that a libretto of such age would be abbreviated and altered to suit contemporary operatic taste; this libretto was unusually old, even older than all but one of the librettos by Metastasio that continued by be set in the 1760s. The cuts and changes in the text made for the 1767 performance of Mysliveček's opera are not attributable. Indeed, they are quite extensive; not a single one of Lucchini's original aria texts was re-set by Mysliveček. However, it is the same cut libretto of Farnace, with small variants, used by the Neapolitan Davide Perez in his opera for the Regio Teatro of Turin in the 1751 Carnival, and repeated in Rome at the Torre Argentina Theater the following year, and in Messina and Naples in 1753 and again in 1757.

Fausta is a melodramma, or opera seria, in two acts by Gaetano Donizetti.

Gloria is a tragic opera in three acts by Francesco Cilea with an Italian libretto by Arturo Colautti. A variation on the Romeo and Juliet story and set in 14th century Siena, the libretto is based on Victorien Sardou's 1874 play La Haine (Hatred). The opera premiered on 15 April 1907 at La Scala conducted by Arturo Toscanini with Solomiya Krushelnytska in the title role. Gloria was a failure at its premiere when it was withdrawn after two performances and fared little better in the 1932 revised version, although there have been two late 20th century revivals. It proved to be Cilea's last staged opera. In the 43 years following the premiere of Gloria he worked on two or three further operas which were never performed and continued to compose chamber and orchestral music.

L'Olimpiade is an 18th-century Italian opera in 3 acts by the Czech composer Josef Mysliveček. It was composed to a libretto by the Italian poet Metastasio that was first performed in 1733. For a performance in the 1770s, it would only be expected that a libretto of such age would be abbreviated and altered to suit contemporary operatic taste; some of the original aria texts would be omitted or substituted, and the remaining aria texts would be set more expansively. In this case, only 14 of the original 18 aria texts of Metastasio were newly set to music. The cuts and changes in the text made for the 1778 performance of Mysliveček's opera are not attributable.

Romolo ed Ersilia is an 18th-century Italian opera in 3 acts by the Czech composer Josef Mysliveček composed to a libretto by the Italian poet Metastasio first produced in Innsbruck in 1765 with music by Johann Adolf Hasse. The drama was one of Metastasio's last, shortest, and least popular. Mysliveček's setting of 1773 was the only other one known to have been produced during the remainder of the eighteenth century. It includes significant alterations, in particular the introduction of new arias that augment the importance of certain characters and the re-ordering of existing arias. The alterations are not attributable. This opera belong to the serious type in Italian language referred to as opera seria. In Mysliveček's day, the opening aria, "Questa è la bella face," the duet that concludes the first act, and the quartet that concludes the second act were famed for their brilliance.

L'ultimo giorno di Pompei influenced either directly or indirectly several other 19th-century works, most notably Karl Bryullov's 1833 painting, The Last Day of Pompeii.

Virginia is an opera, a tragedia lirica, in three acts by composer Saverio Mercadante. The Italian libretto by Salvadore Cammarano is based on Vittorio Alfieri's tragedy of the same name. Alfieri's play was in turn taken from a story in Livy's Ab Urbe condita. Although initially written for performance in 1850 at the Teatro di San Carlo in Naples, the subject matter of Mercadante's opera was objected to by the Bourbon government censors and performance was banned outright.
