Procrustes

Procrustes 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 Procrustes rather than just read about it. In short: In Greek mythology, Procrustes (; Greek: Προκρούστης Prokroustes, "the stretcher [who hammers out the metal]"), also known as Prokoptas, Damastes (Δαμαστής, "subduer") or Polypemon, was a rogue smith and bandit from Attica who attacked people by stretching them or cutting off their legs, so as to force them to fit the size of an iron bed. The word Procrustean is thus used by analogy to describe, for example, situati…

Key takeaways

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

Reference excerpt

In Greek mythology, Procrustes (; Greek: Προκρούστης Prokroustes, "the stretcher [who hammers out the metal]"), also known as Prokoptas, Damastes (Δαμαστής, "subduer") or Polypemon, was a rogue smith and bandit from Attica who attacked people by stretching them or cutting off their legs, so as to force them to fit the size of an iron bed. The word Procrustean is thus used by analogy to describe, for example, situations where an arbitrary standard is used to measure success, while completely disregarding obvious harm that results from the effort.

Family Procrustes was a son of Poseidon while his mother was unknown. Procrustes had a son named Sinis, by Sylea (daughter of Corinthus), who, just as his father, came to be another malefactor captured and killed by Theseus.

Mythology Procrustes had a stronghold on Mount Korydallos at Erineus, on the sacred way between Athens and Eleusis. There he had a bed, in which he invited every passer-by to spend the night, and where he set to work on them with his smith's hammer, to stretch them to fit. In later tellings, if the guest proved too tall, Procrustes would amputate the excess length; if the guest was too short Procrustes would stretch them until they died; nobody ever fit the bed exactly. Procrustes continued his reign of terror until he was captured by Theseus, travelling to Athens along the sacred way, who "fitted" Procrustes to his own bed:

He killed Damastes, surnamed Procrustes, by compelling him to make his own body fit his bed, as he had been wont to do with those of strangers. And he did this in imitation of Heracles. For that hero punished those who offered him violence in the manner in which they had plotted to serve him. Killing Procrustes was Theseus's last adventure on his journey from Troezen to Athens.

A Procrustean bed is an arbitrary standard to which exact conformity is forced.

Worked examples

Example 1 — a first encounter with Procrustes

Start with the simplest possible case. Write down what Procrustes 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 Procrustes 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 Procrustes 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 Procrustes

In research
Procrustes 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 Procrustes 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
Procrustes is common in secondary-school and first-year university syllabi. It links to neighbouring topics Amputation, Egalitarianism, Fictional hoteliers, so understanding it makes those chapters shorter.
In everyday life
Look for Procrustes 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.

Frequently asked questions

What is Procrustes in simple terms?

In Greek mythology, Procrustes (; Greek: Προκρούστης Prokroustes, "the stretcher [who hammers out the metal]"), also known as Prokoptas, Damastes (Δαμαστής, "subduer") or Polypemon, was a rogue smith and bandit from Attica who attacked people by stretching them or cutting off their legs, so as to f…

Why does Procrustes 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 Procrustes?

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.
