Norse Religion – Forn Siðr

Norse religion is a folk religion. Most titles bestowed upon Norse religion are the ones which were used to describe the religion in a competitive manner, usually in a very antagonistic context. Some of these terms were hedendom (Scandinavian), Heidentum (German), Heathenry (English) or Pagan (Latin). A more romanticized name for Norse religion is the medieval Icelandic term Forn Siðr or “Old Custom”.

The key literary texts for the study of Norse religion are the Prose Edda, the Gesta Danorum by Saxo Grammaticus and the Poetic Edda. Sagas are categorized on the basis of when events described in the saga took place. Though Sagas are often mythical in nature the authors’ ambitions are to give a realistic description of past events.

The blót, the form of worship practiced Norse Heathens, resembles that of the Celts, Slavs and Balts; it could occur in sacred groves. It could also take place at home and/or at a simple altar of piled stones known as a hörgr.

Numerous gods are mentioned in the source texts such as the hammer-wielding, humanity-protecting god Thor, who relentlessly fights his foes; the one-eyed, raven-flanked god Odin, who craftily pursues knowledge throughout the worlds and bestowed among humanity the runic alphabet; the beautiful, seiðr-working, feathered cloak-clad goddess Freyja who rides to battle to choose among the slain; the vengeful, skiing goddess Skaði, who prefers the wolf howls of the winter mountains to the seashore; the powerful god Njörðr, who may calm both sea and fire and grant wealth and land; the god Freyr, whose weather and farming associations bring peace and pleasure to humanity; the goddess Iðunn, who keeps apples that grant eternal youthfulness; the mysterious god Heimdallr, who is born of nine mothers, can hear grass grow, has gold teeth, and possesses a resounding horn; the jötunn Loki, who brings tragedy to the gods by engineering the death of the goddess Frigg‘s beautiful son Baldr; and numerous other deities.

The plights of the gods and their interaction with various other beings, such as humanity and the jötnar, beings who may be friends, lovers, foes and/or family members of the gods. The cosmos in Norse mythology consists of Nine Worlds that flank a central cosmological tree, Yggdrasil. Units of time and elements of the cosmology are personified as deities or beings. Various forms of a creation myth are recounted, where the world is created from the flesh of the primordial being Ymir, and the first two humans are Ask and Embla. These worlds are foretold to be reborn after the events of Ragnarök, when an immense battle occurs between the gods and their enemies, and the world is enveloped in flames, only to be reborn anew. There the surviving gods will meet, and the land will be fertile and green, and two humans will repopulate the world.

Central to accounts of Norse mythology are the plights of the gods and their interaction with various other beings, such as with the jötnar, who may be friends, lovers, foes and/or family members of the gods. Numerous gods are mentioned in the source texts. As evidenced by records of personal names and place names, the most popular god among the Scandinavians during the Viking Age was Thor, who is portrayed as unrelentingly pursuing his foes, his mountain-crushing, thunderous hammer Mjölnir in hand. In the mythology, Thor lays waste to numerous jötnar who are foes to the gods or humanity, and is wed to the beautiful, golden-haired goddess Sif.

The god Odin is also frequently mentioned in surviving texts. One-eyed, wolf and raven-flanked, and spear in hand, Odin pursues knowledge throughout the worlds. In an act of self-sacrifice, Odin is described as having hanged himself on the cosmological tree Yggdrasil to gain knowledge of the runic alphabet, which he passed on to humanity, and is associated closely with death, wisdom, and poetry. Odin has a strong association with death; Odin is portrayed as the ruler of Valhalla, where valkyries carry half of those slain in battle. Odin’s wife is the powerful goddess Frigg who can see the future but tells no one, and together they have a beloved son, Baldr. After a series of dreams had by Baldr of his impending death, his death is engineered by Loki, and Baldr thereafter resides in Hel, a realm ruled over by a goddess of the same name.

Odin must share half of his share of the dead with a powerful goddess; Freyja. She is beautiful, sensual, wears a feathered cloak, and practices seiðr. She rides to battle to choose among the slain, and brings her chosen to her afterlife field Fólkvangr. Freyja weeps for her missing husband Óðr, and seeks after him in far away lands. Freyja’s brother, the god Freyr, is also frequently mentioned in surviving texts, and in his association with weather, royalty, human sexuality, and agriculture brings peace and pleasure to humanity. Deeply lovesick after catching sight of the beautiful jötunn Gerðr, Freyr seeks and wins her love, yet at the price of his future doom. Their father is the powerful god Njörðr. Njörðr is strongly associated with ships and seafaring, and so also wealth and prosperity. Freyja and Freyr’s mother is Njörðr’s sister (her name is unprovided in the source material). However, there is more information about his pairing with the skiing and hunting goddess Skaði. Their relationship is ill-fated, as Skaði cannot stand to be away from her beloved mountains, nor Njörðr from the seashore. Together, Freyja, Freyr, and Njörðr form a portion of gods known as the Vanir. While the Aesir and the Vanir retain distinct identification, they came together as the result of the Æsir–Vanir War.

While they receive less mention, numerous other gods and goddesses appear in the source material. Some of the gods we hear less about include the apple-bearing goddess Iðunn and her husband, the skaldic god Bragi; the gold-toothed, white-skinned god Hemdallr, born of nine mothers; the ancient god Týr, who lost a hand while binding the great wolf Fenrir; and the goddess Gefjon, who formed modern day Zealand, Denmark.

Various beings outside of the gods are mentioned. Elves and dwarfs are commonly mentioned and appear to be connected, but their attributes are vague and the relation between the two is ambiguous. Elves are described as radiant and beautiful, whereas dwarfs often act as earthen smiths. A group of beings variously described as jötnar, thursar, and trolls (in English these are all often glossed as “giants”) frequently appear. These beings may either aid, deter, or take their place among the gods. The norns, dísir, and aforementioned valkyries also receive frequent mention. While their functions and roles may overlap and differ, all are collective female beings associated with fate.

The cosmology of the worlds in which all beings inhabit—nine in total—centers around a cosmological tree, Yggdrasil. The gods inhabit the heavenly realm of Asgard whereas humanity inhabits Midgard, a region in the center of the cosmos. Outside of the gods, humanity, and the jötnar, these Nine Worlds are inhabited by beings, such as elves and dwarfs. Travel between the worlds is frequently recounted in the myths, where the gods and other beings may interact directly with humanity. Numerous creatures live on Yggdrasil, such as the insulting messenger squirrel Ratatoskr and the perching hawk Veðrfölnir. The tree itself has three major roots, and at the base of one of these roots live a trio of norns. Elements of the cosmos are personified, such as the Sun (Sól, a goddess), the Moon (Máni, a god), and Earth (Jörð, a goddess), as well as units of time, such as day (Dagr, a god) and night (Nótt, a jötunn).

The afterlife is a complex matter in Norse mythology. The dead may go to the murky realm of Hel—a realm ruled over by a female being of the same name, may be ferried away by valkyries to Odin’s martial hall Valhalla, or may be chosen by the goddess Freyja to dwell in her field Fólkvangr. The goddess Rán may claim those that die at sea, and the goddess Gefjon is said to be attended by virgins upon their death. References to reincarnation are also made. Time itself is presented between cyclic and linear, and some scholars have argued that cyclic time was the original format for the religion. Various forms of a cosmological creation story are provided in Icelandic sources, and references to a future destruction and rebirth of the world—Ragnarok—are frequently mentioned in some texts.


According to the Poetic Edda poem Völuspá and the Prose Edda, the first human couple consisted of Ask and Embla; driftwood found by a trio of gods and imbued with life in the form of three gifts. After the cataclysm of Ragnarok, this process is mirrored in the survival of two humans from a wood; Líf and Lífþrasir. From these two humankind are foretold to repopulate the new, green earth.

Numerous heroes appear in Norse mythology and are celebrated in a variety of poems, songs, and narratives.
