Considered one of the greatest operatic works of all time, the Italian language dramma per musica based on a 1705 stage play by French tragedian Prosper Jolyot de Crébillon about the eponymous King of Crete by Wolfgang Amadeus Mozart had its premiere as the opener for court carnival season in München on this day in 1781. The piece in three acts with ballet interludes tells the story of the homecoming of the commander-in-chief who led the Cretan navy into the Trojan War, comrade of Ajax and rebuffed suitor of Helen, Idomeneus (Ἰδομενεύς—like The Odyssey)—grateful for peaceable relations again after decades of fighting, exercises clemency over prisoners of war brought from Troy, including Priam’s daughter Princess Ilia, though Argonaut Princess Electra is not happy about the potential competition to marry into the dynasty. In contravention to an earlier pledge that would have the king sacrifice his son to the sea on condition of a safe return, Neptune relents and spares the life of the king’s son Prince Idamante, on the promise that he relinquishes his throne to the younger generation, with the new king taking the Trojan princess as his queen. All are happy except Electra—her later parricidical frenzy attributed to this early rejection.
