Question: which has been seen in more than one language Pagliacci: or Oedipus rex?
Context: Oedipus ( or ; Ancient Greek: Οἰδίπους , "Oidípous") is a play by the 5th-century BCE Athenian dramatist Euripides.  The play is now lost except for some fragments.  What survives of the play covers similar ground as Sophocles' acclaimed "Oedipus Rex", but scholars and historians have found there are significant differences.  In "Oedipus Rex", the title character blinds himself upon learning his true parentage, accidentally killing his father and marrying his mother Jocasta.  In Euripides' play, however, it appears Oedipus is blinded by Laius, a servant of his father and Oedipus' predecessor as king of Thebes.  Furthermore, Euripides' play implies Oedipus was blinded before it was known that Laius was his father.  Also, while in Sophocles' play Jocasta kills herself, remaining fragments of Euripides' play depict Jocasta as having survived and accompanied Oedipus into exile. Oedipus and the Sphinx is an 1864 oil on canvas painting by Gustave Moreau that was first exhibited at the French "Salon" of 1864 where it was an immediate success.  It is now in the Metropolitan Museum of Art.  The work was a fresh treatment of the established subject of the meeting between Oedipus and the Sphinx on the road to Delphi, notably portrayed at Sophocles' play Oedipus Rex. Oedipus Rex ("Edipo re") is a 1967 Italian film directed by Pier Paolo Pasolini.  Pasolini adapted the screenplay from the Greek tragedy "Oedipus Rex" written by Sophocles in 428 BC.  The film was mainly shot in Morocco. Polybus (Greek: Πόλυβος ) is a figure in Greek mythology.  He was the king of Corinth and husband of either Merope or Periboea.  He raised Oedipus as his adopted son, who had been abandoned by his parents Laius and Jocasta of Thebes in Greece.  Polybus was the true father of Alcinoe.  In virtually all accounts of the mythology, when Oedipus reached adolescence, he consulted with the Delphic Oracle, who told him "You shall kill your father and marry your mother".  Obviously horrified and disgusted with such a prophecy, Oedipus imposed self-exile upon himself and kept away from Corinth, as he resolved never to murder King Polybus, who had been a kind father to him.  Oedipus was also understandably disgusted the act of murdering Polybus and claiming his wife for himself, as he had no unnatural attraction to Queen Merope.  Many years later, after Oedipus won the kingship of Thebes by defeating the Sphinx, did another plague befall Thebes.  King Oedipus, in his effort to find the cause of plague due to a patricide, revealed that he was told in his teen years that he was destined to murder his father, and sent a spy to Corinth to see who is currently on the throne.  The news of Polybus' death by natural causes was announced by the messenger to Jocasta in Sophocles' "Oedipus Rex", in which it is mistakenly taken to mean that Oedipus did not kill his father.  This would mean that the prophecy that Oedipus would murder his father and marry his mother would be false, and Oedipus expresses relief that he did not commit such a heinous act.  Since Polybus was in fact his adoptive father, Oedipus could and did kill his true father, King Laius, and fulfill the prophecy.  Oedipus never knew his true destiny until the final parts of the play. Oedipus is a "fabula crepidata" (Roman tragic play with Greek subject) of c. 1061 lines of verse that was written by Lucius Annaeus Seneca at some time during the 1st century AD.  It is a retelling of the story of Oedipus, which is better known through the play "Oedipus Rex" by the Athenian playwright, Sophocles.  It is written in Latin.  The play is generally considered one of Seneca's weaker works. Oedipus Rex, also known by its Greek title, Oedipus Tyrannus (Ancient Greek: Οἰδίπους Τύραννος IPA: [oidípuːs týranːos]), or Oedipus the King, is an Athenian tragedy by Sophocles that was first performed around 429 BC.  Originally, to the ancient Greeks, the title was simply "Oedipus" ("Οἰδίπους"), as it is referred to by Aristotle in the "Poetics".  It is thought to have been renamed "Oedipus Tyrannus" to distinguish it from "Oedipus at Colonus".  In antiquity, the term “tyrant” referred to a ruler, but it did not necessarily have a negative connotation. Oedipus rex is an "Opera-oratorio after Sophocles" by Igor Stravinsky, scored for orchestra, speaker, soloists, and male chorus.  The libretto, based on Sophocles's tragedy, was written by Jean Cocteau in French and then translated by Abbé Jean Daniélou into Latin; the narration, however, is performed in the language of the audience. Oedipus Rex is a 1957 film, a film version of the Canadian Stratford Festival production of the William Butler Yeats adaptation of the play "Oedipus Rex" by Sophocles. Pagliacci (] ; literal translation, "Clowns") is an Italian opera in a prologue and two acts, with music and libretto by Ruggero Leoncavallo.  It is the only Leoncavallo opera that is still widely performed.  Opera companies have frequently staged "Pagliacci" with "Cavalleria rusticana" by Mascagni, a double bill known colloquially as 'Cav and Pag'. Oedipus (French: "Œdipe" ) is a tragedy by the French dramatist and philosopher Voltaire that was first performed in 1718.  It was his first play and the first literary work for which he used the pen-name Voltaire (his real name was François-Marie Arouet).  In adapting Sophocles' Athenian tragedy "Oedipus Rex", Voltaire attempted to rationalise the plot and motivation of its characters.  In a letter of 1719 he indicated that he found it improbable that the murder of Laius had not been investigated earlier and that Oedipus should take so long to understand the oracle's clear pronouncement.  Voltaire adds a subplot concerning the love of Philoctète for Jocaste.  He also reduces the prominence of the theme of incest.
