Context paragraphs:
Griselda (A. Scarlatti): Griselda is an opera seria in three acts by the Italian composer Alessandro Scarlatti, the last of Scarlatti’s operas to survive completely today.  The libretto is by Apostolo Zeno, with revisions by an anonymous author.  Zeno wrote his work in 1701 and it had already been set by Pollarolo and Antonio Maria Bononcini (Albinoni, Giovanni Bononcini and Vivaldi would later produce versions).  It is based on the story of Patient Griselda from Boccaccio's "Decameron".  Scarlatti's opera was first performed at the Teatro Capranica, Rome in January, 1721 with an all-male cast (five castratos and a tenor).

Didone abbandonata (Albinoni): Didone abbandonata ("Dido Abandoned") was an opera in three acts composed by Tomaso Albinoni.  Albinoni's music (now lost) was set to Pietro Metastasio's libretto, "Didone abbandonata", which was in turn based on the story of Dido and Aeneas from the fourth book of Virgil's "Aeneid".  The opera premiered on 26 December 1724 at the Teatro San Cassiano in Venice and was the first time that an opera based on a Metastasio libretto was performed in Venice.

La Statira: La Statira is an opera seria in three acts by the Italian composer Tomaso Albinoni with a libretto by Apostolo Zeno and Pietro Pariati.  It was first performed at the Teatro Capranica in Rome during the Carnival season of 1726.  The plot concerns the rivalry between Statira and Barsimo for the throne of Persia.

Atide: Atide is an opera in three acts by Josef Mysliveček set to a libretto by Tomaso Stanzani that is based on Greek legends about Atys, an ancient king of Lydia.  Stanzani's libretto is based on an earlier libretto by Philippe Quinault that was originally set by Jean-Baptiste Lully as "Atys" in 1676.  The opera "Atide" (and all the rest of Mysliveček's operas) belong to the serious type in Italian language referred to as "opera seria".

Adagio in G minor: The Adagio in G minor for violin, strings, and organ continuo is a neo-Baroque composition popularly attributed to the 18th-century Venetian master Tomaso Albinoni, but actually composed by 20th-century musicologist and Albinoni biographer Remo Giazotto, purportedly based on the discovery of a manuscript fragment by Albinoni.  There is a continuing scholarly debate about whether the alleged fragment was real, or a musical hoax perpetrated by Giazotto, but there is no doubt about Giazotto's authorship of the remainder of the work.

Giustino (Handel): Giustino ("Justin", HWV 37) is an opera seria in three acts by George Frideric Handel.  The opera was first given at the Covent Garden Theatre in London on 16 February 1737. The Italian-language libretto was adapted from Charles VI's court poet Pietro Pariati's libretto for "Giustino" (1711), after the much older original libretto of Nicolò Beregan (1682).  The libretto had already been adapted by many composers including Vivaldi's "Giustino" of 1724 and Tomaso Albinoni's lost opera of 1711.

Tomaso Albinoni: Tomaso Giovanni Albinoni (8 June 1671 – 17 January 1751) was an Italian Baroque composer.  While famous in his day as an opera composer, he is mainly remembered today for his instrumental music, such as the concerti.

12 Concerti a cinque (Albinoni): 12 Concerti a cinque (op.  9) is a collection of concertos by the Italian composer Tomaso Albinoni, published in 1722.
