Is Ymir a god, a monster or the world itself? In ymir norse mythology he is a primeval giant, the first living being, killed by Odin, Vili and Vé, whose body the gods then used to build the world.
The best-known accounts are medieval, so the detail of how the world was made from Ymir depends on which text you read. Readers who want to weigh a late retelling against older verse can start with what are primary sources in history, then return here for the passages.
Who Ymir is and what existed before him
Ymir is a primeval giant and the first living being, existing before heaven and earth were created, according to the Völuspá as summarised by Pantheon. That poem pictures the time when Ymir dwelt as a chaotic void with no sand, no sea and no cold waves, and no earth. In other words, Ymir does not live in the world. He is the stuff the world has not yet been made from.
The thirteenth-century Icelander Snorri Sturluson tells of Ymir’s origin in Gylfaginning, and he adds a detail the verse leaves out: Ginnungagap, the Yawning Void, was as mild as windless air before the rime met heat. The same account has Ymir sustained by four streams of milk from the cow Audhumla. The cold, the heat and the cow are all part of a setting in which a giant can exist before any gods do.
Ymir also produces descendants without any partner. While he slept, he sweated, and a man and a woman grew under his left hand, while one foot produced a six-headed son. Some modern summaries call him the hermaphroditic ancestor of all giants, which explains why the giants of later myth are usually traced back to him and the gods are not.
The body and the world: what each text assigns
Each text maps Ymir’s body onto the world, but the three passages below do not assign every part in the same way. The table sets the Poetic Edda’s Vafþrúðnismál beside Snorri’s Gylfaginning and the poem Grímnismál so the differences are visible at a glance.
| Body part | Vafþrúðnismál | Gylfaginning | Grímnismál |
|---|---|---|---|
| Flesh | Earth | Land | Not assigned |
| Bones | Hills | Crags | Not assigned |
| Teeth | Not assigned | Gravel and stones | Not assigned |
| Skull | Heaven | Heaven, with dwarves named East, West, North and South at its corners | Not assigned |
| Blood | Sea | The sea and the waters | Not assigned |
| Sweat | Not assigned | Not assigned | The sea |
| Eyebrows | Not assigned | Not assigned | Midgard |
| Brains | Not assigned | Not assigned | Clouds |
The flesh, bone, teeth, skull and blood entries follow the Vafþrúðnismál and Gylfaginning wording given by Pantheon’s Ymir entry, while the sweat, eyebrow and brain entries come from the Grímnismál lines quoted by Ancient Origins.
The practical reading is straightforward. Flesh, bones and skull are stable across the passages that mention them: land or earth, hills or crags, and heaven. The parts that change are the ones that make the most vivid images, namely the sea and the sky’s contents. If you need a single dependable mapping, use flesh as earth, bones as hills or crags and skull as heaven, and name the text whenever you go beyond those three.
How the gods built the world from the body
Who did it, and where
Ymir was killed by the three sons of Borr, who are Odin, Vé and Vili. In Gylfaginning’s wording, they took Ymir and bore him into the middle of the Yawning Void, Ginnungagap, and there made the world from him. The killing is therefore the founding act of the cosmos, not just a fight won by the gods. The void is the workshop, and the giant’s body is the raw material.
Gylfaginning puts the result plainly: the land was made of his flesh and the crags of his bones, and of his blood the sea and the waters. It then adds that they took his skull also, and made of it the heaven. Nothing in these lines says the gods invented matter. They rearranged what already existed, which is a different claim from creation out of nothing.
Poetic vocabulary that kept the equation alive
The equation between body and world did not stay in the creation narrative. It entered poetic language as kennings, the compressed metaphors of skaldic verse. Heaven could be called the Skull of Ymir, or the Giant’s Skull, earth could be the Flesh of Ymir and the sea the Blood of Ymir. A poet who used those phrases invoked the whole story in a few syllables, so the myth’s persistence in the vocabulary is itself evidence of how familiar the image was.
Where the Eddas differ on Ymir
The two Eddas differ in kind as well as in detail. The Poetic Edda gathers verse such as Völuspá and Vafþrúðnismál. The Prose Edda is Snorri Sturluson’s book, and Gylfaginning (The Fooling of Gylfi) is contained within it. The differences that matter most for Ymir are these:
- The state of the void. Völuspá describes a chaotic void with no sand, sea, waves or earth, while Gylfaginning describes Ginnungagap as mild as windless air before rime met heat. One stresses absence, the other sets a scene in which something can happen.
- The origin of the sea. Gylfaginning makes the sea from Ymir’s blood. Grímnismál says it came from his sweat. The two cannot be merged into one list without choosing, which is why the table keeps them in separate columns.
- How much belongs to Snorri. Historians still find it difficult to know exactly what content Snorri made up and what was original. A detail found only in Gylfaginning, such as the dwarves at the four corners of the skull, is best treated as Snorri’s telling, not as settled older belief.
The verse suits readers who want the oldest wording and are comfortable with compression. The prose suits readers who want a connected sequence from the void to the finished world. Choose the Poetic Edda for wording and the Prose Edda for narrative order, and expect gaps in both.
Misunderstandings worth correcting
- “Ymir is a god.” He is a giant, and the gods are a separate group. The killers are the sons of Borr, and the myth is built on the contrast between the giant who comes first and the gods who give his body its shape.
- “The gods made the world from nothing.” The texts describe reworking an existing body. Ymir lives before heaven and earth, and the gods supply the arrangement, not the material.
- “The Edda says…” This phrase hides which text is meant. A Völuspá line, a Vafþrúðnismál line, a Grímnismál line and a Gylfaginning line can each say something different about the same giant, so name the poem or the prose work when you quote.

Frequently asked questions
| Question | Answer |
|---|---|
| Is Aurgelmir another name for Ymir? | Probably. Historians think the name Aurgelmir, used in Vafþrúðnismál, was another name for Ymir, so a passage about Aurgelmir is usually read as a passage about him. |
| Why is Ymir sometimes called hermaphroditic? | Some modern summaries describe him as the hermaphroditic ancestor of all giants. The description presents him as a single being who is the source of the giant line, with no partner in the story. |
| Who were the parents of Odin, Vili and Vé? | Their father was Borr, who mated with a giantess named Bestla. The gods who killed Ymir therefore had a giantess as a mother, according to Ancient Origins. |
