full_context: Document 1: Isus (mythology): Isus was a minor character in Greek mythology mentioned in Homer's "Iliad", one of the 50 sons of King Priam by an unidentified woman. He was killed by Agamemnon. Little is known of Isus other than brief mentions or relatives. He was known as a brother of Antiphus, son of Priam and Hecuba.

Tithonus is also described by most sources as Laomedon's eldest legitimate son; and most sources omit Ganymedes from the list of Laomedon's children, but indicate him as his uncle instead. Laomedon's possible wives are Placia, Strymo (or Rhoeo) and Leucippe; by the former he begot Tithonus and by the latter King Priam (see John Tzetzes' "Scholia in Lycophronem" 18 («ὁ μὲν γὰρ Πρίαμος ἦν Λευκίππης, ὁ δὲ Τιθωνὸς Ῥοιοῦς ἢ Στρυμοῦς τῆς Σκαμάνδρου θυγατρὸς υἱός» : "Priamus was the son of Leucippe, whereas Tithonus was the son of Rhoeo or Strymo, the daughter of Scamander")). He also had a son named Bucolion by the nymph Calybe, as recounted by Homer in the "Iliad" (6.22). Dictys Cretensis (4.22) added Thymoetes to the list of Laomedon's children.

The mass is sometimes termed a missa brevis et solemnis , because it is short in a simple structure as a missa brevis, but festively scored like a missa solemnis with brass and timpani in addition to four soloists, strings and organ. It was possibly first performed on 7 April 1776 in a mass for Easter at the Salzburg Cathedral. The nickname is derived from violin figures in the Hosanna which resemble bird chirping.

Document 10: Trojan War: In Greek mythology, the Trojan War was waged against the city of Troy by the Achaeans (Greeks) after Paris of Troy took Helen from her husband Menelaus, king of Sparta. The war is one of the most important events in Greek mythology and has been narrated through many works of Greek literature, most notably through Homer's "Iliad". The "Iliad" relates four days in the tenth year of the decade-long siege of Troy; the "Odyssey" describes the journey home of Odysseus, one of the war's heroes. Other parts of the war are described in a cycle of epic poems, which have survived through fragments. Episodes from the war provided material for Greek tragedy and other works of Greek literature, and for Roman poets including Virgil and Ovid.

Document 13: La clemenza di Tito (Mysliveček): La clemenza di Tito ("The Clemency of Titus") 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 1734 with music of Antonio Caldara. 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 (similar to the setting of the same text by Wolfgang Amadeus Mozart). The cuts and changes in the text made for the 1774 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.
