Question: Tony Harrison created renditions of the ancient Greek dramatic work Oresteia written by which author?

<P0-S0>  The trilogy—consisting of "Agamemnon" (Ἀγαμέμνων ), "The Libation Bearers" (Χοηφóρoι ), and "The Eumenides" (Εὐμενίδες )—also shows how the Greek gods interacted with the characters and influenced their decisions pertaining to events and disputes. <P0-S1>  The only extant example of an ancient Greek theatre trilogy, the "Oresteia" won first prize at the Dionysia festival in 458 BC. <P0-S2>  Many consider the "Oresteia" to be Aeschylus' finest work. <P0-S3>  The principal themes of the trilogy include the contrast between revenge and justice, as well as the transition from personal vendetta to organized litigation. <P0-S4> The Oresteia (Ancient Greek: Ὀρέστεια ) is a trilogy of Greek tragedies written by Aeschylus concerning the murder of Agamemnon by Clytaemnestra, the murder of Clytaemnestra by Orestes, the trial of Orestes, the end of the curse on the House of Atreus and pacification of the Erinyes. <P0-S5>  "Orestia" originally included a satyr play, "Proteus" (Πρωτεύς ), following the tragic trilogy, but all except a single line of "Proteus" has been lost. <SEP> <P1-S0> The Prometheia (Ancient Greek: Προμήθεια ) is a trilogy of plays about the titan Prometheus. <P1-S1>  It was attributed in Antiquity to the 5th-century BC Greek tragedian Aeschylus. <P1-S2>  Though an Alexandrian catalogue of Aeschylean play titles designates the trilogy "Hoi Prometheis" ("the Prometheuses"), in modern scholarship the trilogy has been designated the "Prometheia" to mirror the title of Aeschylus' only extant trilogy, the "Oresteia". <P1-S3>  Unlike the "Oresteia", only one play from this trilogy—"Prometheus Bound"—survives. <P1-S4>  Inasmuch as the authorship of "Prometheus Bound" continues to be debated, the very existence of a Prometheus trilogy is uncertain. <P1-S5>  To the extent that modern scholars postulate the existence of such a trilogy by a single author, the consensus holds that it comprised "Prometheus Bound", "Prometheus Unbound", and "Prometheus the Fire-Bringer", in that order. <SEP> <P2-S0> The Labourers of Herakles is a 1995 play created by English poet and playwright Tony Harrison. <P2-S1>  It is partially based on remaining fragments of tragedies by ancient Greek dramatist Phrynichos, one of the earliest tragedians. <P2-S2>  Harrison's play deals with genocide and ethnic cleansing and uses Heracles's filicide as a metaphor for the unspeakable horrors of war and man's inhumanity to man. <SEP> <P3-S0> Tony Harrison (born 30 April 1937) is an English poet, translator and playwright. <P3-S1>  He was born in Leeds and he received his education in Classics from Leeds Grammar School and Leeds University. <P3-S2>  He is one of Britain's foremost verse writers and many of his works have been performed at the Royal National Theatre. <P3-S3>  He is also noted for his outspoken views, particularly those on the Iraq War. <P3-S4>  In 2015, he was honoured with the David Cohen Prize in recognition for his body of work. <P3-S5>  He is noted for controversial works such as the poem "V", as well as his versions of dramatic works: from ancient Greek such as the tragedies "Oresteia" and "Lysistrata", from French Molière's "The Misanthrope", from Middle English "The Mysteries".
