Question: are Il re pastore and King Priam both Operas ?
Context: In Greek mythology, Laomedon ( ; Ancient Greek: Λαομέδων ) was a Trojan king, son of Ilus, nephew of Ganymede and Assaracus, and father of Priam, Astyoche, Lampus, Hicetaon, Clytius, Cilla, Proclia, Aethilla, Medesicaste, Clytodora, and Hesione.  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. In Greek mythology, Hyrtacus ( ; Greek: Ὕρτακος ) is an obscure character associated with the Trojan War.  He was a comrade of King Priam of Troy.  Hyrtacus married Arisbe, daughter of King Merops of Percote, after Priam had divorced her to marry Hecabe.  Hyrtacus's son by Arisbe was named Asius and fought at Troy.  In the "Aeneid", Hyrtacus is credited with two more sons, Nisus and Hippocoon.  Hyrtacus's own parentage is not given. Il re pastore ("The Shepherd King") is an opera, K. 208, written by Wolfgang Amadeus Mozart to an Italian libretto by Metastasio, edited by Giambattista Varesco.  It is an opera seria.  The opera was first performed on 23 April 1775 in Salzburg, at the Palace of the Archbishop Count Hieronymus von Colloredo. In Greek mythology, Teucer ( ), also Teucrus, Teucros or Teucris (Greek: Τεῦκρος, "Teukros" ), was the son of King Telamon of Salamis Island and Hesione, daughter of King Laomedon of Troy.  He fought alongside his half-brother, Ajax, in the Trojan War and is the legendary founder of the city of Salamis on Cyprus.  Through his mother, Teucer was the nephew of King Priam of Troy and the cousin of Hector and Paris—all of whom he fought against in the Trojan War. In Greco-Roman mythology, Aeneas ( ; Greek: Αἰνείας, "Aineías", possibly derived from Greek αἰνή meaning "praised") was a Trojan hero, the son of the prince Anchises and the goddess Venus (Aphrodite).  His father was a first cousin of King Priam of Troy (both being grandsons of Ilus, founder of Troy), making Aeneas a second cousin to Priam's children (such as Hector and Paris).  He is a character in Greek mythology and is mentioned in Homer's "Iliad".  Aeneas receives full treatment in Roman mythology, most extensively in Virgil's "Aeneid," where he is an ancestor of Romulus and Remus.  He became the first true hero of Rome.  Snorri Sturluson identifies him with the Norse Æsir Vidarr. Ascanius ( ) (said to have reigned 1176-1138 BC) a legendary king of Alba Longa and is the son of the Trojan hero Aeneas and Creusa, daughter of Priam.  He is a character in Roman mythology, and has a divine lineage, being the son of Aeneas, who is the son of the goddess Venus and the hero Anchises, a relative of the king Priam; thus Ascanius has divine ascendents by both parents, being descendant of god Jupiter, his wife Juno and Dardanus.  He is also an ancestor of Romulus, Remus and the Gens Julia.  Together with his father, he is a major character in Virgil's "Aeneid", and he is depicted as one of the founders of the Roman race. Demoleon ( died circa 1190 B.C.) was a Trojan warrior.  The son of Antenor and Theano, he was a tough defensive fighter that was killed by Achilles during the Trojan War. Born into a peaceful family that believed that Helen should be sent back to the Greeks, he had many siblings including Archelochus, Acamas, Glaucus, Helicaon, Laodocus, Coön, Polybus, Agenor, Iphidamas, Laodamas, Eurymachus, Hippolochus, Medon, Thersilochus, Antheus (most of whom perished during the Trojan War), and at least one sister, Crino.  His father was a counselor to King Priam and his mother was a priestess of Athena.  He was the grandson of Thracian king Cisseus and Telecleia, and his house was spared by the Achaeans because his family received Odysseus and Menelaus when they came to Troy as envoys.  Demoleon's house was also spared by the Achaeans because his father pleaded with the Trojans to return Helen to the Greeks when Paris first stole her from Menelaus.  It is believed that his family founded the city of Patavium (Padua) after fleeing Troy. Percote was a town or city on the southern (Asian) side of the Hellespont, to the northeast of Troy.  Percote is mentioned a few times in Greek mythology, where it plays a very minor role each time.  It was said to be the home of a notable seer named Merops, also its ruler.  Merops was the father of Arisbe (the first wife of King Priam, and subsequently wife of King Hyrtacus), Cleite (wife of King Cyzicus), and two sons named Amphius and Adrastus who fought during the Trojan War.  As an ally of Troy, Percote sent a contingent to help King Priam during the Trojan War - though this contingent was led not by Merops's sons, but by Asius, son of Hyrtacus, according to Homer's Iliad, one native from Percote was wounded in the Trojan War by Antilochus, two natives from Percote were killed in the Trojan War by Diomedes and Ullysses.  The Meropidae (Amphius and Adrastus) instead lead a contingent from nearby Adrastea.  A nephew of Priam, named Melanippus, son of Hicetaon, herded cattle (oxen) at Percote, according to Homer. 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. King Priam is an opera by Michael Tippett, to his own libretto.  The story is based on Homer's "Iliad", except the birth and childhood of Paris, which are taken from the "Fabulae" of Hyginus.
