Context_1 : Papyrus Oxyrhynchus 44 (P. Oxy. 44) is a "sale of taxes," from Paniscus to Asclepiades, written in Greek. It was discovered by Grenfell and Hunt in 1897 in Oxyrhynchus. The document was written between the years 66 and 70, although Grenfell and Hunt dated it to the end of the first century. It is housed in the British Museum (749) in London. The text was published by Grenfell and Hunt in 1898. Context_2 : Euripides ( or ; Greek: ; ] ) (c. 480 c. 406 BC) was a tragedian of classical Athens. Along with Aeschylus and Sophocles, he is one of the three ancient Greek tragedians a number of whose plays have survived. Some ancient scholars attributed 95 plays to him but according to the "Suda" it was 92 at most. Of these, 18 or 19 have survived more or less complete (there has been debate about his authorship of "Rhesus", largely on stylistic grounds) and there are also fragments, some substantial, of most of the other plays. More of his plays have survived intact than those of Aeschylus and Sophocles together, partly due to mere chance and partly because his popularity grew as theirs declinedhe became, in the Hellenistic Age, a cornerstone of ancient literary education, along with Homer, Demosthenes and Menander. Context_3 : Cratippus (AncientGreek: ; fl. c. 375 BC) was a Greek historian. There are only three or four references to him in ancient literature, and his importance derives from his being identified by several scholars (e.g. Blass) with the author of the historical fragment discovered by Grenfell and Hunt. The fragment itself was published in "Oxyrhynchus Papyri", vol. v, and is known as the "Hellenica Oxyrhynchia". It may be regarded as a fairly certain inference from a passage in Plutarch ("De Gloria Atheniensium ", p.345 E, ed. Bernardakis, ii. p.455) that he was an Athenian writer, intermediate in date between Thucydides and Xenophon, and that his work continued the narrative of Thucydides, from the point at which the latter historian stopped (410 BC) down to the Battle of Cnidus. Context_4 : Euphorion (Greek: , "Euphorion") was the son of the Greek tragedian Aeschylus, and himself an author of tragedies. In the Dionysia of 431 BCE, Euphorion won 1st prize, defeating both Sophocles (who took 2nd prize) and Euripides, who took 3rd prize with a tetralogy that includes the extant play "Medea". He is purported by some to have been the author of "Prometheus Bound"previously assumed to be the work of his father, to whom it was attributed at the Library of Alexandria,for several reasons, chiefly that the playwright's portrayal of Zeus is far less reverent than in other works attributed to Aeschylus, and that references to the play appear in the plays of the comic Aristophanes. This has led historians to date it as late as 415 BCE, long after Aeschylus's death. If Euphorion wrote "Prometheus Bound", there are as a result five ancient Greek tragedians with one or more fully surviving plays: Aeschylus, Euphorion, Sophocles, Euripides, and the unknown author of the tragedy Rhesus. Context_5 : Papyrus Oxyrhynchus 22 (P. Oxy. 22) contains fragments of the "Oedipus Tyrannus" by Sophocles, written in Greek. It was discovered by Grenfell and Hunt in 1897 in Oxyrhynchus. The fragment is dated to the fifth century. It is housed in the British Library (Department of Manuscripts). The text was published by Grenfell and Hunt in 1898. Context_6 : Phrynichus ( ; Greek: ), son of Polyphrasmon the Elder and pupil of Thespis, was one of the earliest of the Greek tragedians. Some of the ancients regarded him as the real founder of tragedy. Phrynichus is said to have died in Sicily. His son Polyphrasmon was also a playwright. Context_7 : In Greek mythology, Creusa (; Ancient Greek: "Kreousa" "princess" ) or Glauce ( ; Ancient Greek: "blue-gray"), Latin Glauca, was the daughter of King Creon of Corinth, Greece, in whose favor Jason abandoned Medea. In the version of the myth commonly followed by ancient tragedians, Medea obtained her revenge by giving Creusa a dress that had been cursed by the sorceress. The curse caused the dress to stick to Creusa's body and burn her to death as soon as she put it on. Context_8 : Sophocles ( ; Greek: , "Sophokles", ] ; 497/6 winter 406/5 BC) is one of three ancient Greek tragedians whose plays have survived. His first plays were written later than those of Aeschylus, and earlier than or contemporary with those of Euripides. Sophocles wrote 120 plays during the course of his life, but only seven have survived in a complete form: "Ajax", "Antigone", "The Women of Trachis", "Oedipus Rex", "Electra", "Philoctetes" and "Oedipus at Colonus". For almost 50 years, Sophocles was the most celebrated playwright in the dramatic competitions of the city-state of Athens that took place during the religious festivals of the Lenaea and the Dionysia. He competed in 30 competitions, won 24, and was never judged lower than second place. Aeschylus won 13 competitions, and was sometimes defeated by Sophocles, while Euripides won 4 competitions. Context_9 : Greek tragedy is a form of theatre from Ancient Greece and Asia Minor. It reached its most significant form in Athens in the 5th century BC, the works of which are sometimes called Attic tragedy. Greek tragedy is widely believed to be an extension of the ancient rites carried out in honor of Dionysus, and it heavily influenced the theatre of Ancient Rome and the Renaissance. Tragic plots were most often based upon myths from the oral traditions of archaic epics. In tragic theatre, however, these narratives were presented by actors. The most acclaimed Greek tragedians are Aeschylus, Sophocles and Euripides. Context_10 : Paestum was a major ancient Greek city on the coast of the Tyrrhenian Sea in Magna Graecia (southern Italy). The ruins of Paestum are famous for their three ancient Greek temples in the Doric order, dating from about 600 to 450 BC, which are in a very good state of preservation. The city walls and amphitheatre are largely intact, and the bottom of the walls of many other structures remain, as well as paved roads. The site is open to the public, and there is a modern national museum within it, which also contains the finds from the associated Greek site of Foce del Sele. fact_1 : 22) contains fragments of the "Oedipus Tyrannus" by Sophocles, written in Greek. fact_2 : It was discovered by Grenfell and Hunt in 1897 in Oxyrhynchus. fact_3 : Sophocles ( ; Greek: , "Sophokles", ] ; 497/6 winter 406/5 BC) is one of three ancient Greek tragedians whose plays have survived. Answer: Sophocles
Output:
A work of what one of the three ancient Greek tragedians was discovered by Grenfell and Hunt?
