Scylla

Scylla 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 Scylla rather than just read about it. In short: In Greek mythology, Scylla ( SIL-ə; Ancient Greek: Σκύλλα, romanized: Skýlla, pronounced [skýlːa]) is a legendary, man-eating monster that lives on one side of a narrow channel of water, opposite her counterpart, the sea-swallowing monster Charybdis. The two sides of the strait are within an arrow's range of each other—so close that sailors attempting to avoid the whirlpools of Charybdis would pass dangerously close…

Key takeaways

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

Reference excerpt

In Greek mythology, Scylla ( SIL-ə; Ancient Greek: Σκύλλα, romanized: Skýlla, pronounced [skýlːa]) is a legendary, man-eating monster that lives on one side of a narrow channel of water, opposite her counterpart, the sea-swallowing monster Charybdis. The two sides of the strait are within an arrow's range of each other—so close that sailors attempting to avoid the whirlpools of Charybdis would pass dangerously close to Scylla and vice versa. Scylla is first attested in Homer's Odyssey, where Odysseus and his crew encounter her and Charybdis on their travels. Later myth provides an origin story as a beautiful nymph who is transformed into a monster. Book Three of Virgil's Aeneid associates the strait where Scylla dwells with the Strait of Messina between Calabria, a region of Southern Italy, and Sicily. The coastal town of Scilla in Calabria takes its name from the mythological figure of Scylla and it is said to be the home of the nymph. The Byzantine encyclopedia Suda describes Scylla as having the appearance of a beautiful woman "as far as its eyes," with six dog heads on each side, and a serpent body below. The idiom "between Scylla and Charybdis" has come to mean being forced to choose between two similarly undesirable or risky outcomes, similar to "between a rock and a hard place".

Parentage

The parentage of Scylla varies according to author. Homer, Ovid, Apollodorus, Servius, and a scholiast on Plato, all name Crataeis as the mother of Scylla. Neither Homer nor Ovid mentions a father, but Apollodorus says that the father was either Trienus (probably a textual corruption of Triton) or Phorcus (a variant of Phorkys). Similarly, the Plato scholiast, perhaps following Apollodorus, gives the father as Tyrrhenus or Phorcus, while Eustathius on Homer, Odyssey 12.85, gave the father as Triton, or Poseidon and Crataeis as the parents. Other authors have Hecate as Scylla's mother. The Hesiodic Megalai Ehoiai gives Hecate and Phorbas as the parents of Scylla, while Acusilaus says that Scylla's parents were Hecate and Phorkys (so also scholia on Odyssey 12.85). Perhaps trying to reconcile these conflicting accounts, Apollonius of Rhodes says that Crataeis was another name for Hecate, and that she and Phorcys were the parents of Scylla. Likewise, Semos of Delos says that Crataeis was the daughter of Hecate and Triton, and mother of Scylla by Deimos. Stesichorus (alone) names Lamia as the mother of Scylla, possibly the Lamia who was the daughter of Poseidon, while according to Hyginus, Scylla was the offspring of Typhon and Echidna.

Narratives According to John Tzetzes and Servius' commentary on the Aeneid, Scylla was a beautiful naiad who was claimed by Poseidon, but the jealous Nereid Amphitrite turned her into a terrible monster by poisoning the water of the spring where Scylla would bathe. A similar story is found in Hyginus, according to whom Scylla was loved by Glaucus, but Glaucus himself was also loved by the goddess sorceress Circe. While Scylla was bathing in the sea, the jealous Circe poured a baleful potion into the sea water which caused Scylla to transform into a frightful monster with six dog forms springing from her thighs. In this form, she attacked Odysseus' ship, robbing him of his companions. In a late Greek myth, recorded in Eustathius' commentary on Homer and John Tzetzes, Heracles encountered Scylla during a journey to Sicily and slew her. Her father, the sea-god Phorcys, then applied flaming torches to her body and restored her to life.

Homer's Odyssey

In Homer's Odyssey XII, Odysseus is advised by Circe to sail closer to Scylla, something he never told the rest of his crew, for Charybdis could drown his whole ship: "Hug Scylla's crag—sail on past her—top speed! Better by far to lose six men and keep your ship than lose your entire crew." She also tells Odysseus to ask Scylla's mother, the river nymph Crataeis, to prevent Scylla from pouncing more than once. Odysseus successfully navigates the strait, but when he and his crew are momentarily distracted by Charybdis, Scylla snatches six sailors off the deck and devours them alive.

Ovid's Metamorphoses

According to Ovid, the fisherman-turned-sea god Glaucus falls in love with the beautiful Scylla, but she is repulsed by his piscine form and flees to a promontory where he cannot follow. When Glaucus goes to Circe to request a love potion that will win Scylla's affections, the enchantress herself becomes enamored with him. Meeting with no success, Circe becomes hatefully jealous of her rival and therefore prepares a vial of poison and pours it into the sea pool where Scylla regularly bathed, transforming her into a thing of terror even to herself.

Gaius Julius Hyginus recounts the same version of the story in his Fabulae. The story was later adapted into a five-act tragic opera, Scylla et Glaucus (1746), by the French composer Jean-Marie Leclair.

Keats' Endymion In John Keats' loose retelling of Ovid's version of the myth of Scylla and Glaucus in Book 3 of Endymion (1818), the evil Circe does not transform Scylla into a monster but merely murders the beautiful nymph. Glaucus then takes her corpse to a crystal palace at the bottom of the ocean where lie the bodies of all lovers who have died at sea. After a thousand years, she is resurrected by Endymion and reunited with Glaucus.

Worked examples

Example 1 — a first encounter with Scylla

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

In research
Scylla 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 Scylla 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
Scylla is common in secondary-school and first-year university syllabi. It links to neighbouring topics Characters in the Argonautica, Characters in the Odyssey, Children of Apollo, so understanding it makes those chapters shorter.
In everyday life
Look for Scylla 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.
