Thor fishes for the world-serpent

An immense catch puts Thor face to face with the serpent that encircles the human world.

A fishing trip inside a larger quest

In Hymiskviða, the gods need a cauldron large enough for Ægir to brew their feast. Týr says that his father Hymir possesses one, so he and Thor travel to Hymir’s home. The visit becomes a contest of appetite and strength. Thor eats so much that the household needs fresh provisions, and he joins Hymir at sea. For bait he tears the head from an ox.

Hymir catches whales, while Thor’s line reaches something far more dangerous: the serpent that surrounds the world. Thor hauls the creature upward and strikes its head with his hammer. The poem describes the earth shaking and the serpent sinking beneath the water. It does not narrate Hymir cutting the fishing line. After their return, Thor breaks a cup against Hymir’s unexpectedly hard head, carries away the cauldron, and overcomes the pursuers. The fishing is one episode in the successful acquisition of a feast’s equipment.

The prose version changes the encounter

In Gylfaginning, Thor visits Hymir without Týr and appears as a young man. Hymir initially underestimates him. Thor rows farther out than his host wishes, baits a strong hook with an ox’s head, and pulls up the serpent. His feet break through the boat as he braces himself. The god and the creature stare at one another while the serpent sprays venom.

Here Hymir panics and cuts the line just as Thor raises his hammer. Thor throws the hammer after the sinking serpent. The narrator acknowledges a report that the blow killed it, then explicitly prefers its continued survival in the sea. Thor strikes Hymir and wades ashore. This ending preserves the serpent for the final encounter at Ragnarök, but the prose itself admits that another outcome circulated.

Keep the uncertainty visible

A modern retelling can easily combine the poem’s cauldron quest with the prose knife-cut and present the result as one source. The selector below keeps their different actions separate. Hymiskviða’s sinking serpent is not an unambiguous death certificate; Snorri’s account is not silent about competing endings.

The encounter pits overwhelming strength against the edge of the known world. That is a useful reading of the scene, not a claim that every historical audience gave it a single symbolic meaning. Its surviving texts are medieval Icelandic witnesses to older narrative material whose precise composition and transmission remain debated.

Time & the surviving record
Period / witness
Poetic Edda witnesses chiefly thirteenth century CE; Prose Edda composed c.1220 and preserved in later copies. Mythic events are undated.
Recording context
Medieval Icelandic textual preservation; the principal Poetic Edda manuscript, Codex Regius, dates to c.1270. Recording and copying locations do not establish the birthplace of a story.

A recording location is not necessarily a story’s origin. Dates of texts, copies, and translations answer different questions.
