What is the River Styx?
The Styx is a river of the Greek underworld and also a goddess, a daughter of Ocean. Her name is related to a word for hatred or shuddering. In Hesiod she is honoured because she sided with Zeus against the Titans, and her reward is that the gods swear by her water. A god who breaks such an oath lies without breath for a year and is shut out from the company of the gods for nine more.
In later tellings the Styx is the water the dead must cross, and Charon ferries them over it, though older sources give that crossing to the river Acheron. The underworld has other rivers too, among them Lethe, the river of forgetting.

What sets Styx apart
The Styx is the only underworld river that is also a power over the gods. Her water is the pledge of their oaths, and the penalty for breaking one is exact: a year lying without breath or voice, then nine years shut out of the councils and feasts. Her role as the river of the ferry is later and borrowed from the Acheron. The Greeks counted five rivers below, and hers is the one named for hatred.
- Name: related to Greek stygein, to hate or shudder at
- Parentage: daughter of Ocean and Tethys, in Hesiod
- Penalty for a broken oath: one year breathless, nine years exiled from the gods
- The other four rivers: Acheron, Cocytus, Phlegethon and Lethe
- Achilles story: first in Statius, first century CE
Often mistaken for something else: Lethe is the river of forgetting, which souls meet before a new life; the Styx is the river of oaths and, in later poets, of the crossing.
The story behind Styx
The oath by the Styx is already in the Iliad, and Hesiod's Theogony, about 700 BCE, explains it. Virgil's Aeneid made it the river of Charon's ferry for most later readers. The story that Thetis dipped the infant Achilles in it, leaving his heel unprotected, is first told by the Roman poet Statius in the first century CE. A mountain stream in Arcadia was shown to travellers as the Styx.
Why Styx matters
Styx was the one thing that bound the Greek gods themselves, which shows that even they were pictured as answerable to something.
How to read Styx
Writers use the river as a figure for the border of death, and the adjective Stygian for anything very dark.
Styx in practice: an example
A reader meets a character said to have crossed the Styx and knows that it means dying, by way of a ferry and a coin.
Where readings of Styx go wrong
The dipping of Achilles is a late addition and is not in Homer. The river belongs to poetry, and the house sends no one across it.

Common questions
What is the River Styx?
It is the chief river of the Greek underworld and also a goddess. The gods swore their most solemn oaths by its water, and later stories have the dead ferried across it.
Who ferries the dead across the Styx?
Charon, an old ferryman who is paid a small coin. Older sources place his ferry on the river Acheron; Virgil and later writers made the Styx the usual crossing.
Was Achilles really dipped in the Styx?
Not in Homer. The story appears with the Roman poet Statius in the first century CE, some eight hundred years after the Iliad.
