Norse/Germanic mythology and religion contain no formal doctrines concerning what happens to a human, or, for that matter, a member of any other species, when he or she dies. What happens to the body and the other, less tangible parts of the self varies widely from case to case, and depends on a staggering array of factors that, unfortunately, are only dimly understood nowadays due to the fragmentary character of the sources we possess concerning Norse mythology and pre-Christian Germanic religion more broadly.
Still, some general – although not necessarily universal – patterns can be discerned. The resting place of the dead is located beneath the ground – a literal “underworld” that comprises a spiritual counterpart to the physical grave. The dead can interact with the living and vice versa, and oftentimes a part of the dead person is reborn. Finally, unlike in, say, Christian or Muslim perspectives on the afterlife, there’s little to no moral dimension to the indigenous northern European perspective; there’s no eternal bliss or eternal torment, just a transition to another stage in the endless cycle of being.
The Land of the Dead
The pre-Christian spiritual traditions of the Germanic peoples, like those of animistic and pantheistic peoples the world over, view spirit and matter as being intimately intertwined rather than separable into an exclusively corporeal realm and an exclusively “incorporeal” realm. Thus it should come as no surprise that the heathen land of the dead is a literal underworld that closely corresponds to the grave, located within the ground and especially concentrated around burial sites.
The Norse mythological texts record three primary places where the dead were perceived to go: Helheim (Old Norse Helheimr, “the home of the goddess Hel“), Valhalla (Old Norse Valhöll, “the hall of the fallen”), and Folkvang (Old Norse Fólkvangr, “the field of the people” or “the field of warriors”). Countless theories have been proposed regarding exactly what the differences between these places are, but a closer look at the primary sources reveals that they’re practically indistinguishable from one another and are all slightly different conceptions of – one could even say that they’re merely different names for – the underworld.
Helheim (or simply “Hel,” as it is also sometimes called) is the vaguest and most general term for the underworld. In Old Norse colloquial usage, it means “the grave” or something to that effect. Valhalla is presided over by Odin, and to gain entrance to it, one must be chosen by him and his valkyries, the “choosers of the fallen.” Similarly, entrance to Folkvang is dependent upon being selected by Freya. The distinction between Valhalla and Folkvang isn’t altogether clear, because the principal Old Norse source that describes the two halls depicts Freya in terms that suggest she’s a valkyrie herself. Valhalla is often depicted as a realm where distinguished warriors engage in a continuous battle, and just such a place is described, in important early sources, as being located beneath the ground – and, intriguingly, without the name “Valhalla” or a cognate anywhere in the account. Furthermore, the very name Valhöll, “the hall of the fallen,” is a late development that seems to have arisen out of the name Valhallr, “the rock of the fallen,” a title given to certain rocks and hills where the dead were perceived to dwell in southern Sweden, one of the greatest historical centers of Odin-worship.
The only Old Norse text that makes a sure distinction between Valhalla and Helheim is the Prose Edda of Snorri Sturluson. Snorri, a thirteenth-century Christian scholar, claims that those who die in battle are taken to Valhalla, while those who die of sickness or old age are taken to Helheim. Yet he blatantly contradicts this statement in the one extensive account of Helheim he provides – namely the tale of the death of Baldur, Odin’s own son, who was killed violently and was nevertheless borne to Hel. No other source makes this distinction – and several contradict it – which means that this distinction between Helheim and Valhalla is certainly an invention of Snorri’s.
Thus we see that the different versions of the underworld are hardly distinguishable, if at all. What, then, is this place like? The sources present no uniform portrait, and some depict it in much more pleasant terms than others, but the one theme that stands out in all of these disparate accounts is just how much it resembles the world of the living: the dead eat, drink, carouse, fight, sleep, practice magic, and generally do all of the things that Viking Age men and women typically did. To die is merely to continue living, albeit in a somewhat different form.
Rebirth and the Continuing Presence of the Dead
In the pre-Christian Germanic worldview, as in the worldviews of other animistic peoples from every corner of the world, the self is not thought of as being an isolated, monadic entity, as it is in Christian and post-Christian societies, for example. Rather, the boundaries between the self and its environment are exceedingly blurry, and the self is composed of various detachable parts. Upon death or sometime thereafter, these parts go their separate ways.
Part of the self lingers in the underworld and retains his or her former personality and appearance. This part of the self is venerated as an ancestor (unless the person had been especially hated or feared, or had returned to haunt the living with malicious intent), and the living can communicate with this part of the dead person indefinitely.
But other parts of the dead man or woman don’t rest in the grave. The hamingja (an Old Norse word for “luck” that was conceived of as being a personal entity in its own right) is often reborn into a descendent, especially if the child is given the name of the original owner of the hamingja. This was a very common practice in the Viking Age.
It’s often impossible to distinguish between ancestors and elves in Old Norse literature, to the point that it wouldn’t be amiss to speak of a part of the dead human becoming an elf in some cases. One example of this comes from The Saga of Olaf the Holy, one of the first Christian kings of Norway. Olaf and a servant ride past the burial mound of the king’s ancestor and namesake, who is now called by the name of Ólaf Geirstaðaálfr – literally “Olaf, the Elf of Geirstad,” a title that clearly implies the currently elfin state of the king’s forefather. The same passage also insinuates that King Olaf is the reincarnation of the deceased Olaf, presumably through the hamingja.
The possibility of transmigration – being reborn as a different species – is also present in the surviving material concerning the ancient Germanic worldview, although, fragmentary as the sources are, no specific instances of this have come down to us. Another prominent part of the self is the fylgja (Old Norse “follower”), an animal spirit that has a significant influence on the person’s character. (Having a bear fylgja is a sign of noble birth, a wolf of savagery, a pig of gluttony, etc.). We also know that the ancient Germanic peoples saw the boundary between the human and animal worlds as being quite porous, as evidenced especially by the numerous examples of shapeshifting and totemism in the period sources. No surviving source tells us what happens to the fylgja after death, but – and this is an open question – is it far-fetched to surmise that it’s reborn into its proper species?
In the worldview of the pre-Christian northern Europeans, life is eternal. But not in the sense that most people today automatically think of when they hear that phrase; rather, the particular bundle of fragmentary parts that you call your “self” dissolves into its components, who then go on to vitalize your descendents and their world, just as your rotting corpse nourishes the beings around it – worms, bugs, trees, flowers. Death is a threshold in the wider process of life, not so much an end as a continuance and a transformation.
