Norse Mythology - Yggdrasil, The Cosmic Tree

in mythology •  2 years ago  (edited)

Yggdrasil, the noblest of trees is a cosmic tree that connects the nine worlds in Norse Mythology. It is an ash tree that stands in the center of the cosmos. Its roots reach into three different worlds while its branches extend far into heavens.

Yggdrasil is holy to both men and gods. The gods assemble at Yggdrasil every day to attend to their daily business. Even the etymology of the name comes from Odin’s sacrifice. Ygg is one of Odin’s names and drasill means horse. “The horse of the hanged” was one of the expressions used to describe gallows; Odin sacrificed himself to himself by hanging himself on Yggdrasil.

I know that I hung on a windy tree
nine long nights,
wounded with a spear, dedicated to Odin,
myself to myself,
on that tree of which no man knows
from where its roots run.

Stanza from Hávamál, a poem from the Poetic Edda

Yggdrasil is not only a tree that supports and connects the cosmos. It is also home to many creatures that live within it. The most notable of the creatures that live there are an unnamed eagle and a squirrel; the four stags Dáinn, Dvalinn, Duneyrr and Duraþrór; and the dragon Níðhöggr.

The Nine Worlds

In the Old Norse sources, the nine worlds around Yggdrasil are mentioned several times. Although we know there are nine of them, the names and the locations of all of the worlds are never stated outright. There are few worlds that are mentioned by their names and the names of the others can be deduced from various sources. On the other hand, the locations of the worlds remain unclear.

The nine worlds of the Old Norse mythology are:

  • Asgard – The home of the Æsir

  • Álfheimr/Ljósálfheimr – The home of the Ljósálfar (the Light Elves)

  • Niðavellir/Svartálfaheimr – The home of the Dwarves

  • Midgard – Earth, home of humans

  • Jötunheimr – The home of the Frost Giants

  • Vanaheimr – The home of the Vanir

  • Nilfheim – World of the primordial frost

  • Muspelheim – World of primordial fire

  • Hel – The home of the dishonorable dead, ruled by the goddess Hel

One of the Yggdrasil’s roots extends into the spring Mímisbrunnr which is located in Jötunheimr, the world of the frost giants. Mímisbrunnr is the spring which contains wisdom and intelligence. The master of the spring is Mimir, who is full of knowledge and wisdom because he drinks from the well every day. Mímisbrunnr is also a resting place of Odin’s eye. Odin placed it there as a pledge to be allowed to drink a single sip of the water from Mímisbrunnr.

Another of the three primary roots of Yggdrasil extends through Hel and all the way to Hvergelmir. Hverglermir is the spring located in Nilfheim the realm of the primordial frost. It is the spring from which all the waters came. The frozen rivers which were necessary for the creation of the world come from Hverglemir.
The well is mentioned in another place in the Poetic Edda, the poem Grímnismál. The poem describes the stag Eikthyrnir. The stag stands on top of Valhalla and eats leaves of Yggdrasil. Liquid flows from its antlers all the way to Hverglemir and in turn feed one of the roots of Yggdrasil.

The third root that supports Yggdrasil extends to the holy well of Urðarbrunnr. The well is associated with the trio of Norns (maidens) Urðr, Verðandi, and Skuld who laid the laws of the men and shape the lives of mankind. Urðarbrunnr is said to be located in the heavens among the Æsir; from that, we can deduce that it is located somewhere in Asgard, the fortress of the gods.

Not much is known of the connection of the other worlds with Yggdrasil, the sources only agree that Yggdrasil connects them all.

The Creatures of Yggdrasil

Níðhöggr is a dragon who lives in Hvergelmir with countless other serpents. He gnaws at the root of Yggdrasil from below. It is believed that those who committed the worst possible crimes are located in the bottom of the root that extends to Hvergelmir. Níðhöggr role is to chew their corpses together with the root.

On the other side of the world, on top of the Yggdrasill is an eagle with a hawk Veðrfölnir sitting between his eyes. Eagle has can see the realms below with his sharp eyes and has knowledge of many things. A squirrel Ratatösk runs up and down the tree and tells slanderous gossip provoking the eagle and Níðhöggr

Four stags stand on the highest boughs of Yggdrasil. They crane their necks upward and chomp at the branches eating Yggdrasil. The names of the stags are Dáinn, Dvalinn, Duneyrr, and Duraþrór. There are two interpretations of the meaning behind the stags. Early theories interpret them as the symbol for the four seasons. A later theory by Finnur Magnússon suggests that the stags represent winds and that their biting of the leaves represents winds tearing at clouds.

There are many other creatures living on and within the tree, but these are the only ones we know by the names. If you are interested in Norse Mythology, check out my earlier post about the creation of the world in Norse mythology.

Awesome introduction to Yggdrasil and Norse mythology!

Thanks to @paradigmprospect, this post was resteemed and highlighted in today's edition of The Daily Sneak.

Thank you for your efforts to create quality content!

Thx for resteem :)

The squirrel is named Ratatoskr and the eagle is named Veðrfölnir.

Ratatoskr is also correct, it is just a difference in two different translations.

Veðrfölnir is not the eagle himself, he is the hawk is perched between eagles eyes. He has a role similar to one that Huginn and Muninn have in relation to Odin. He travels across the world to bring knowledge to the eagle.

The Yggdrasil tree is at the center of Ragnarok and the poetic edda paints such an image of its destruction but we are getting ahead of ourselves.

The depiction of the 9 realms which the roots of the tree are found shows such a diverse environment and creatures inhabiting it.

There will be destruction when hosts of Muspelheim ride over Bifrost, but the fate of Yiggdrasil remains unknown :)

Very informative. Thank you fo me making me a bit smarter today. :) Yggdrasil has three roots - intelligence, creation and laws. Great way to teach younger generations on pillars of mankind(my opinion at least)

I agree with your opinion, in a way those three are the basics of human civilization.

You should enter this in the Minnow Support Saturday contest.

I like the contest but it doesn't fit with my concept of the blog. If I won I would have an obligation to write a new post on Tuesday to be published. I write series of posts so I would either have to postpone a post in my pirate series, as I won't have time to write both before Tuesday; publish my pirate post as a part of contest on other blog which I am unwilling to do, or write a crappy post with little effort for Tuesday part of the contest which I don't find fair.

That is understandable. I respect your decision to maintain the quality of your work.

From what Era is this passage taken from

Which passage? If you mean the one about Odin is from Hávamál, a poem from the Poetic Edda. The Poetic Edda itself dates to 13 century, the songs in the Poetic Edda are older than that but we don't know when the songs themselves were written.
