Peripeteia

Peripeteia is a science topic covered in the lgStudy science library. This page brings together a partial reference excerpt, illustrations, worked examples, real-world applications and a short study plan, so you can understand Peripeteia rather than just read about it. In short: Peripeteia (, peripety, alternative Latin form: Peripetīa, ultimately from Greek: περιπέτεια) is a reversal of circumstances, or turning point, within a work of literature. Aristotle's view Aristotle, in his Poetics, defines peripeteia as "a change by which the action veers round to its opposite, subject always to our rule of probability or necessity." According to Aristotle, peripeteia, along with discovery, is the…

Key takeaways

  • Peripeteia belongs to science; place it in that map before memorising details.
  • Learn the definition first, then one example that makes the definition concrete.
  • Connect Peripeteia to a quantity you can measure, compute or draw — that is where exam questions come from.
  • Reproduce the core statement of Peripeteia from memory before moving on to harder problems.

Reference excerpt

Peripeteia (, peripety, alternative Latin form: Peripetīa, ultimately from Greek: περιπέτεια) is a reversal of circumstances, or turning point, within a work of literature.

Aristotle's view Aristotle, in his Poetics, defines peripeteia as "a change by which the action veers round to its opposite, subject always to our rule of probability or necessity." According to Aristotle, peripeteia, along with discovery, is the most effective when it comes to drama, particularly in a tragedy. He wrote that "The finest form of Discovery is one attended by Peripeteia, like that which goes with the Discovery in Oedipus...". Aristotle says that peripeteia is the most powerful part of a plot in a tragedy along with discovery (anagnorisis). A peripety is the change of the kind described from one state of things within the play to its opposite, and that too in the way we are saying, in the probable or necessary sequence of events. There is often no element like Peripeteia; it can bring forth or result in terror, mercy, or in comedies it can bring a smile or it can bring forth tears (Rizo). This is the best way to spark and maintain attention throughout the various form and genres of drama "Tragedy imitates good actions and, thereby, measures and depicts the well-being of its protagonist. But in his formal definition, as well as throughout the Poetics, Aristotle emphasizes that" ... Tragedy is an imitation not only of a complete action, but also of events inspiring fear or pity" (1452a 1); in fact, at one point Aristotle isolates the imitation of "actions that excite pity and fear" as "the distinctive mark of tragic imitation" (1452b 30). Pity and fear are effected through reversal and recognition; and these "most powerful elements of emotional interest in Tragedy-Peripeteia or Reversal of the Situation, and recognition scenes-are parts of the plot (1450a 32). has the shift of the tragic protagonist's fortune from good to bad, which is essential to the plot of a tragedy. It is often an ironic twist. Good uses of Peripeteia are those that especially are parts of a complex plot, so that they are defined by their changes of fortune being accompanied by reversal, recognition, or both" (Smithson). Peripeteia includes changes of character, but also more external changes. A character who becomes rich and famous from poverty and obscurity has undergone peripeteia, even if his character remains the same. When a character learns something he had been previously ignorant of, this is normally distinguished from peripeteia as anagnorisis or discovery, a distinction derived from Aristotle's work. Aristotle considers anagnorisis, leading to peripeteia, the mark of a superior tragedy. Two such plays are Oedipus Rex, where the oracle's information that Oedipus has killed his father and married his mother brings about his mother's death and his own blindness and exile, and Iphigenia in Tauris, where Iphigenia realizes that the strangers she is to sacrifice are her brother and his friend, resulting in all three of them escaping Tauris. These plots he considered complex and superior to simple plots without anagnorisis or peripeteia, such as when Medea resolves to kill her children, knows they are her children, and does so. Aristotle identified Oedipus Rex as the principal work demonstrating peripety. (See Aristotle's Poetics.)

Examples

Oedipus Rex In Sophocles' Oedipus Rex, the peripeteia occurs towards the end of the play when the Messenger brings Oedipus news of his parentage. In the play, Oedipus is fated to murder his father and marry his mother. His parents, Laius and Jocasta, try to forestall the oracle by sending their son away to be killed, but he is actually raised by Polybus and his wife, Merope, the rulers of another kingdom. The irony of the Messenger’s information is that it was supposed to comfort Oedipus and assure him that he was the son of Polybus. Unfortunately for Oedipus, the Messenger says, "Polybus was nothing to you, [Oedipus] that’s why, not in blood" (Sophocles 1113). The Messenger received Oedipus from one of Laius’ servants and then gave him to Polybus. The plot comes together when Oedipus realizes that he is the son and murderer of Laius as well as the son and husband of Jocasta. Martin M. Winkler says that here, peripeteia and anagnorisis occur at the same time "for the greatest possible impact" because Oedipus has been "struck a blow from above, as if by fate or the gods. He is changing from the mighty and somewhat arrogant king of Thebes to a figure of woe" (Winkler 57).

Conversion of Paul on the road to Damascus

The instantaneous conversion of Paul on the road to Damascus is a classic example of peripeteia, which Eusebius presented in his Life of Constantine as a pattern for the equally revelatory conversion of Constantine. Modern biographers of Constantine see his conversion less as a momentary phenomenon than as a step in a lifelong process.

Worked examples

Example 1 — a first encounter with Peripeteia

Start with the simplest possible case. Write down what Peripeteia claims or describes in one sentence, then invent the smallest concrete situation in which that sentence is true. In science, the smallest case is usually a single object, a single equation or a single measurement. Check that every symbol or term in your sentence has a meaning in that case.

Example 2 — changing one variable

Take the situation from Example 1 and change exactly one quantity: double it, halve it, or set it to zero. Predict what should happen to Peripeteia before you calculate. Comparing your prediction with the result is the fastest way to find out whether you understand the idea or only the words.

Example 3 — an exam-style question

Typical questions about Peripeteia ask you to (a) state it precisely, (b) apply it to given data, and (c) explain a limitation. Practise writing all three answers in under five minutes; the third part is what separates a full-mark answer from an average one.

Applications of Peripeteia

In research
Peripeteia appears in science research whenever the underlying quantities have to be modelled precisely. Papers usually cite it as a starting assumption and then explore where it breaks down.
In technology and industry
Engineering practice reuses Peripeteia in design rules, simulations and safety margins. Knowing the idea lets you read a specification sheet and understand why the numbers look the way they do.
In the classroom
Peripeteia is common in secondary-school and first-year university syllabi. It links to neighbouring topics Ancient Greek theatre, Concepts in ancient Greek aesthetics, Narratology, so understanding it makes those chapters shorter.
In everyday life
Look for Peripeteia outside the textbook — in sport, cooking, traffic, electronics or the sky above you. An example you found yourself is remembered far longer than one you were given.

Why does Peripeteia matter?

Because it connects several science ideas at once: it gives you a definition you can apply, a quantity you can calculate, and a way to check whether a result is plausible.

How should I study Peripeteia?

Read the excerpt, restate it from memory, then work through the examples and applications listed on this page. The five-step study plan above takes about twenty minutes.
