Question: Around what year was the Greek play that inspired Jean Anouilh's play of the same name written?

full_context: Document 1: Tereus (play): Tereus (Ancient Greek: Τηρεύς , "Tēreus") is a Greek play by the Athenian poet Sophocles. Although the play has been lost, several fragments have been recovered. Although the date that the play was first produced is not known, it is known that it was produced before 414 BCE, because the Greek comedic playwright Aristophanes referenced "Tereus" in his play "The Birds", which was first performed in 414. Thomas B. L. Webster dates the play to near but before 431 BCE, based on circumstantial evidence from a comment Thucydides made in 431 about the need to distinguish between Tereus and the King of Thrace, Teres, which Webster believes was made necessary by the popularity of Sophocles play around this time causing confusion between the two names. Based on references in "The Birds" it is also known that another Greek playwright, Philocles, had also written a play on the subject of Tereus, and there is evidence both from "The Birds" and from a scholiast that Sophocles' play came first.

A different television adaptation aired in 1958 in Australia. There is another English translation by Christopher Fry."
Document 3: Theatre of ancient Greece: The ancient Greek drama was a theatrical culture that flourished in ancient Greece from c. 700 BC. The city-state of Athens, which became a significant cultural, political, and military power during this period, was its center, where it was institutionalised as part of a festival called the Dionysia, which honoured the god Dionysus. Tragedy (late 500 BC), comedy (490 BC), and the satyr play were the three dramatic genres to emerge there. Athens exported the festival to its numerous colonies and allies in order to promote a common cultural identity.
Document 4: Kostas Triantafyllopoulos: Kostas Triantafyllopoulos (also written as Kostas Triantafillopoulos) (Greek: Κώστας Τριανταφυλλόπουλος ) (born 8 February 1956 in Athinaio, Arcadia, Greece) is a Greek actor. He graduated from Theodosiadis's Drama School of Athens in 1977 and he has played a wide variety of roles on stage from Greek tragedy, Aristophanes and Shakespeare to contemporary American drama (Eugene O'Neill, Arthur Miller, Tennessee Williams, Joyce Carol Oates, Thornton Wilder, Sam Shepard).

From November 1998 to July 1999 and from July 2002 to March 2003 he participated in the world grand tours of the National Theatre of Greece with the tragedies "Medea" by Euripides (Creon), "Electra" (Paedagogus) and "Antigone" (Guard) both by Sophocles.

Document 7: No Exit: No Exit (French: "Huis Clos" , ] ) is a 1944 existentialist French play by Jean-Paul Sartre. The original title is the French equivalent of the legal term "in camera", referring to a private discussion behind closed doors. The play was first performed at the Théâtre du Vieux-Colombier in May 1944. The play begins with three characters who find themselves waiting in a mysterious room. It is a depiction of the afterlife in which three deceased characters are punished by being locked into a room together for eternity. It is the source of Sartre's especially famous and often misinterpreted quotation "L'enfer, c'est les autres" or "Hell is other people", a reference to Sartre's ideas about the and the perpetual ontological struggle of being caused to see oneself as an object from the view of another consciousness.
Document 8: Oedipus (Voltaire play): 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.
Document 9: Tragedy: Tragedy (from the Greek: τραγῳδία , "tragōidia" ) is a form of drama based on human suffering that invokes an accompanying catharsis or pleasure in audiences. While many cultures have developed forms that provoke this paradoxical response, the term "tragedy" often refers to a specific tradition of drama that has played a unique and important role historically in the self-definition of Western civilisation. That tradition has been multiple and discontinuous, yet the term has often been used to invoke a powerful effect of cultural identity and historical continuity—"the Greeks and the Elizabethans, in one cultural form; Hellenes and Christians, in a common activity," as Raymond Williams puts it.
Document 10: Antidosis: Antidosis (Ancient Greek ἀντίδοσις ), is the title of a speech treatise by the ancient Greek rhetorician, Isocrates. The "Antidosis" can be viewed as a defense, an autobiography, or rhetorical treatise. However, since Isocrates wrote it when he was 82 years old, it is generally seen by some people as an autobiography. The title literally translates as “an exchange,” and was applied in ancient Greek courts as a peculiar law pertaining to an exchange of estates between two parties. If one of the 1200 wealthiest Athenians eligible was tasked with the performance of a public liturgy and financing one of the many public concerns of Athens, then he could avoid the duty by nominating a richer man who was more qualified than himself to perform it. If the supposedly richer man disagreed with the terms, then the entirety of their estates would be exchanged and the now more wealthy man would have to perform the liturgy, as originally planned. The law inspired Isocrates' "Antidosis", which was written in the form of a court case where Isocrates had to defend himself from a charge of corrupting the youth by teaching them how to speak well in order for them to gain an unfair advantage over their peers. Although this work is put forward by Isocrates as his imagined defense in a legal case, it is more a treatise on morality and teaching.
Document 11: Antony and Cleopatra: Antony and Cleopatra is a tragedy by William Shakespeare. The play was performed first circa 1607 at the Blackfriars Theatre or the Globe Theatre by the King's Men.
Document 12: Saraqinisht: Saraqinisht is a small village of the former Antigonë municipality in the Gjirokastër County, southern Albania.

Near the village are the remains of the ancient city of Antigonea, which was founded by Pyrrhus of Epirus, and named after his wife, Antigone. Saraqinisht is inhabited by an Orthodox Albanian population and an Aromanian minority.
Document 13: Jean Racine: Jean Racine (] ), baptismal name Jean-Baptiste Racine (22 December 163921 April 1699), was a French dramatist, one of the three great playwrights of 17th-century France (along with Molière and Corneille), and an important literary figure in the Western tradition. Racine was primarily a tragedian, producing such "examples of neoclassical perfection" as "Phèdre", "Andromaque", and "Athalie", although he did write one comedy, "Les Plaideurs", and a muted tragedy, "Esther", for the young.
Document 14: Eurydice (Anouilh play): Eurydice is a play by French writer Jean Anouilh, written in 1941. The story is set in the 1930s, among a troupe of travelling performers. It combines skepticism about romance in general and the intensity of the relationship between Orpheus and Eurydice with an other-worldly mysticism. The result is a heavily ironic modern retelling of the classical Orpheus myth. The play has also been performed under the title Point of Departure, a translation by Kitty Black, and on Broadway as Legend of Lovers, in a 1951 production by the Theatre Guild.
Document 15: Antigone (Anouilh play): Jean Anouilh's play Antigone is a tragedy inspired by Greek mythology and the play of the same name by Sophocles. In English, it is often distinguished from its antecedent by being pronounced similarly to its original French form [ɑ̃tiɡɔn], approximately "on-tee-GONE".
