Euripides in the context of "The Frogs"

A tragedy is a genre of drama based on human suffering and, mainly, the terrible or sorrowful events that befall a main character or cast of characters. Traditionally, the intention of tragedy is to invoke an accompanying catharsis, or a "pain [that] awakens pleasure," for the audience. 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 civilization. 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.

Originating in the theatre of ancient Greece 2500 years ago, where only a fraction of the works of Aeschylus, Sophocles and Euripides survive, as well as many fragments from other poets, and the later Roman tragedies of Seneca; through its singular articulations in the works of Shakespeare, Lope de Vega, Jean Racine, and Friedrich Schiller to the more recent naturalistic tragedy of Henrik Ibsen and August Strindberg; Nurul Momen's Nemesis' tragic vengeance & Samuel Beckett's modernist meditations on death, loss and suffering; Heiner Müller postmodernist reworkings of the tragic canon, tragedy has remained an important site of cultural experimentation, negotiation, struggle, and change. A long line of philosophers—which includes Plato, Aristotle, Saint Augustine, Voltaire, Hume, Diderot, Hegel, Schopenhauer, Kierkegaard, Nietzsche, Freud, Benjamin, Camus, Lacan, and Deleuze—have analysed, speculated upon, and criticised the genre.

Aristophanes (/ˌærɪˈstɒfəniːz/; Ancient Greek: Ἀριστοφάνης [aristopʰánɛːs]; c. 446 – c. 386 BC) was an Ancient Greek comic playwright from Athens. He wrote in total forty plays, of which eleven survive virtually complete today. The majority of his surviving plays belong to the genre of comic drama known as Old Comedy and are considered its most valuable examples. Aristophanes's plays were performed at the religious festivals of Athens, mostly the City Dionysia and the Lenaia, and several of them won the first prize in their respective competitions.

Also known as "The Father of Comedy" and "the Prince of Ancient Comedy", Aristophanes wrote plays that often dealt with real-life figures, including Euripides and Alcibiades, and contemporary events, such as the Peloponnesian War. He has been said to recreate the life of ancient Athens more convincingly than any other author. His plays are characterized by preposterous premises, explicit language, wordplays, and political satire. His powers of ridicule were feared and acknowledged by influential contemporaries; Plato singled out Aristophanes's play The Clouds as slander that contributed to the trial and subsequent condemning to death of Socrates, although other satirical playwrights had also caricatured the philosopher.

Sophocles (/ˈsɒfəkliːz/; Ancient Greek: Σοφοκλῆς, pronounced [so.pʰo.klɛ̂ːs], Sophoklễs; c. 497/496 – winter 406/405 BC) was an ancient Greek tragedian, one of three from whom at least two plays have survived in full. His first plays were written later than, or contemporary with, those of Aeschylus and earlier than, or contemporary with, those of Euripides. Sophocles wrote more than 120 plays, but only seven have survived in a complete form: Ajax, Antigone, 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, which 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 beaten by Sophocles; Euripides won four.

The most famous tragedies of Sophocles feature Oedipus and Antigone: they are generally known as the Theban plays, though each was part of a different tetralogy (the other members of which are now lost). Sophocles influenced the development of drama, most importantly by adding a third actor (attributed to Sophocles by Aristotle; to Aeschylus by Themistius), thereby reducing the importance of the chorus in the presentation of the plot. He also developed his characters to a greater extent than earlier playwrights.

Ancient Greek literature is literature written in the Ancient Greek language from the earliest texts until the time of the Byzantine Empire. The earliest surviving works of ancient Greek literature, dating back to the early Archaic period, are the two epic poems the Iliad and the Odyssey, set in an idealized archaic past today identified as having some relation to the Mycenaean era. These two epics, along with the Homeric Hymns and the two poems of Hesiod, the Theogony and Works and Days, constituted the major foundations of the Greek literary tradition that would continue into the Classical, Hellenistic, and Roman periods.

The lyric poets Sappho, Alcaeus, and Pindar were highly influential during the early development of the Greek poetic tradition. Aeschylus is the earliest Greek tragic playwright for whom any plays have survived complete. Sophocles is famous for his tragedies about Oedipus, particularly Oedipus the King and Antigone. Euripides is known for his plays which often pushed the boundaries of the tragic genre. The comedic playwright Aristophanes wrote in the genre of Old Comedy, while the later playwright Menander was an early pioneer of New Comedy. The historians Herodotus of Halicarnassus and Thucydides, who both lived during the fifth century BC, wrote accounts of events that happened shortly before and during their own lifetimes. The philosopher Plato wrote dialogues, usually centered around his teacher Socrates, dealing with various philosophical subjects, whereas his student Aristotle wrote numerous treatises, which later became highly influential.

In Greek mythology, Neoptolemus (/ˌniːəpˈtɒlɪməs/; Ancient Greek: Νεοπτόλεμος, romanized: Neoptólemos, lit. 'new warrior'), originally called Pyrrhus at birth (/ˈpɪrəs/; Πύρρος, Pýrrhos, 'red'), was the son of the mythical warrior Achilles and the princess Deidamia, and the brother of Oneiros. He became the progenitor of the ruling dynasty of the Molossians of ancient Epirus. In a reference to his pedigree, Neoptolemus was sometimes called Achillides (from his father Achilles' name) or, from his grandfather's or great-grandfather's names, Pelides or Aeacides. According to Plutarch, Neoptolemus was the ancestor of Pyrrhus of Epirus.

Pythia (/ˈpɪθiə/; Ancient Greek: Πυθία [pyːˈtʰíaː]) was the title of the high priestess of the Temple of Apollo at Delphi in central Greece. She served as its oracle and was known as the Oracle of Delphi. Her title was sometimes historically glossed in English as the Pythoness.

The Pythia was established at the latest in the 8th century BC (though some estimates date the shrine to as early as 1400 BC), and was widely credited for her prophecies uttered under divine possession (enthusiasmos) by Apollo. The Pythian priestess emerged as pre-eminent by the end of the 7th century BC and continued to be consulted until the late 4th century AD. During this period, the Delphic Oracle was the most prestigious and authoritative oracle among the Greeks, and she was among the most powerful women of the classical world. The oracle is one of the best-documented religious institutions of the classical Greeks. Authors who mention the oracle include Aeschylus, Aristotle, Clement of Alexandria, Diodorus, Diogenes, Euripides, Herodotus, Julian, Justin, Livy, Lucan, Nepos, Ovid, Pausanias, Pindar, Plato, Plutarch, Sophocles, Strabo, Thucydides, and Xenophon.

Helen (Ancient Greek: Ἑλένη, romanized: Helénē), also known as Helen of Troy, or Helen of Sparta, and in Latin as Helena, was a figure in Greek mythology said to have been the most beautiful woman in the world. She was believed to have been the daughter of Zeus by Leda or Nemesis, and the sister of Clytemnestra, Castor, Pollux, Philonoe, Phoebe and Timandra. She was first married to King Menelaus of Sparta "who became by her the father of Hermione, and, according to others, of Nicostratus also." Her subsequent marriage to Paris of Troy was the most immediate cause of the Trojan War.

Elements of her putative biography come from ancient Greek and Roman authors such as Homer, Hesiod, Euripides, Virgil and Ovid. In her youth, she was abducted by Theseus. A competition between her suitors for her hand in marriage saw Menelaus emerge victorious. All of her suitors were required to swear an oath (known as the Oath of Tyndareus) promising to provide military assistance to the winning suitor, if Helen were ever stolen from him. The obligations of the oath precipitated the Trojan War. When she married Menelaus she was still very young. In most accounts, including Homer's, Helen ultimately fell in love with Paris and willingly went to Troy with him, though there are also stories in which she was abducted.

Greek tragedy (Ancient Greek: τραγῳδία, romanized: tragōidía) is one of the three principal theatrical genres from Ancient Greece and Greek-inhabited Anatolia, along with comedy and the satyr play. 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, the god of wine and theatre, and it greatly 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. These tragedians often explored many themes of human nature, mainly as a way of connecting with the audience but also as way of bringing the audience into the play.

A tragic hero (or sometimes tragic heroine if they are female) is the protagonist of a tragedy. In his Poetics, Aristotle records the descriptions of the tragic hero to the playwright and strictly defines the place that the tragic hero must play and the kind of man he must be. Aristotle based his observations on previous dramas. Many of the most famous instances of tragic heroes appear in Greek literature, most notably the works of Sophocles and Euripides.
