Yggdrasil is an immense mythical tree that plays a central role in Norse cosmology, where it connects the Nine Worlds.
Yggdrasil is attested in the Poetic Edda, compiled in the 13th century from earlier traditional sources, and the Prose Edda, written in the 13th century by Snorri Sturluson.
In both sources, Yggdrasil is an immense ash tree that is center to the cosmos and considered very holy. The gods go to Yggdrasil daily to assemble at their things, traditional governing assemblies.
The branches of Yggdrasil extend far into the heavens, and the tree is supported by three roots that extend far away into other locations; one to the well Urðarbrunnr in the heavens, one to the spring Hvergelmir, and another to the well Mímisbrunnr.
Creatures live within Yggdrasil, including the dragon Níðhöggr, an unnamed eagle, and the stags Dáinn, Dvalinn, Duneyrr and Duraþrór.
Conflicting scholarly theories have been proposed about the etymology of the name Yggdrasill, the possibility that the tree is of another species than ash, its connection to the many sacred trees and groves in Germanic paganism and mythology, and the fate of Yggdrasil during the events of Ragnarök.
Hilda Ellis Davidson comments that the existence of nine worlds around Yggdrasil is mentioned more than once in Old Norse sources, but the identity of the worlds is never stated outright, though it can be deduced from various sources.
Davidson comments that “no doubt the identity of the nine varied from time to time as the emphasis changed or new imagery arrived“.
Davidson says that it is unclear where the nine worlds are located in relation to the tree; they could either exist one above the other or perhaps be grouped around the tree, but there are references to worlds existing beneath the tree, while the gods are pictured as in the sky, a rainbow bridge (Bifröst) connecting the tree with other worlds.
Davidson opines that “those who have tried to produce a convincing diagram of the Scandinavian cosmos from what we are told in the sources have only added to the confusion“.
Davidson notes parallels between Yggdrasil and shamanic lore in northern Eurasia:
The conception of the tree rising through a number of worlds is found in northern Eurasia and forms part of the shamanic lore shared by many peoples of this region. This seems to be a very ancient conception, perhaps based on the Pole Star, the center of the heavens, and the image of the central tree in Scandinavia may have been influenced by it… Among Siberian shamans, a central tree may be used as a ladder to ascend the heavens.
Davidson says that the notion of an eagle atop a tree and the world serpent coiled around the roots of the tree has parallels in other cosmologies from Asia.
She goes on to say that Norse cosmology may have been influenced by these Asiatic cosmologies from a northern location.
Davidson adds, on the other hand, that it is attested that the Germanic peoples worshiped their deities in open forest clearings and that a sky god was particularly connected with the oak tree, and therefore “a central tree was a natural symbol for them also“.
Mímameiðr, Hoddmímis holt, and Ragnarök
Connections have been proposed between the wood Hoddmímis holt (Old Norse “Hoard-Mímir’s” holt) and the tree Mímameiðr (“Mímir’s tree”), generally thought to refer to the world tree Yggdrasil, and the spring Mímisbrunnr.
John Lindow concurs that Mímameiðr may be another name for Yggdrasil and that if the Hoard-Mímir of the name Hoddmímis holt is the same figure as Mímir (associated with the spring named after him, Mímisbrunnr), then the Mímir’s holt—Yggdrasil—and Mímir’s spring may be within the same proximity.
Carolyne Larrington notes that it is nowhere expressly stated what will happen to Yggdrasil during the events of Ragnarök.
Larrington points to a connection between the primordial figure of Mímir and Yggdrasil in the poem Völuspá, and theorizes that “it is possible that Hoddmimir is another name for Mimir, and that the two survivors hide in Yggdrasill.”
Rudolf Simek theorizes that the survival of Líf and Lífþrasir through Ragnarök by hiding in Hoddmímis holt is “a case of reduplication of the anthropogeny, understandable from the cyclic nature of the Eddic eschatology.”
Simek says that Hoddmímis holt “should not be understood literally as a wood or even a forest in which the two keep themselves hidden, but rather as an alternative name for the world-tree Yggdrasill. Thus, the creation of mankind from tree trunks (Askr, Embla) is repeated after the Ragnarǫk as well.”
Simek says that in Germanic regions, the concept of mankind originating from trees is ancient. Simek additionally points out legendary parallels in a Bavarian legend of a shepherd who lives inside a tree, whose descendants repopulate the land after life there has been wiped out by plague (citing a retelling by F. R. Schröder).
In addition, Simek points to an Old Norse parallel in the figure of Örvar-Oddr, “who is rejuvenated after living as a tree-man (Ǫrvar-Odds saga 24–27)“.
Warden trees, Irminsul, and sacred trees
Continuing as late as the 19th century, warden trees were venerated in areas of Germany and Scandinavia, considered to be guardians and bringers of luck, and offerings were sometimes made to them.
A massive birch tree standing atop a burial mound and located beside a farm in western Norway is recorded as having had ale poured over its roots during festivals. The tree was felled in 1874.
Davidson comments that “the position of the tree in the center as a source of luck and protection for gods and men is confirmed” by these rituals to Warden Trees.
Davidson notes that the gods are described as meeting beneath Yggdrasil to hold their things and that the pillars venerated by the Germanic peoples, such as the pillar Irminsul, were also symbolic of the center of the world.
Davidson details that it would be difficult to ascertain whether a tree or pillar came first and that this likely depends on if the holy location was in a thickly wooded area or not.
Davidson notes that there is no mention of a sacred tree at Þingvellir in Iceland yet that Adam of Bremen describes a huge tree standing next to the Temple at Uppsala in Sweden, which Adam describes as remaining green throughout summer and winter, and that no one knew what type of tree it was.
Davidson comments that while it is uncertain that Adam’s informant actually witnessed that tree is unknown, but that the existence of sacred trees in pre-Christian Germanic Europe is further evidenced by records of their destruction by early Christian missionaries, such as Thor’s Oak by Saint Boniface.
Ken Dowden comments that behind Irminsul, Thor’s Oak in Geismar, and the sacred tree at Uppsala “looms a mythic prototype, an Yggdrasil, the world-ash of the Norsemen“.
