Introduction to Norse Mythology

Norse mythology is the body of myths, legends, and religious beliefs held by the pre-Christian Germanic peoples of Scandinavia, the North Atlantic, and the British Isles. It centers on a cast of gods — chief among them Odin, Thor, and Freya — and on a vivid cosmology built around the great ash tree Yggdrasil and the nine worlds it sustains. Its stories chronicle the creation of the cosmos, the wars of the gods, the deeds of legendary heroes, and a foretold apocalypse called Ragnarok in which most of the divine order will perish and the world will be reborn.

These myths survive in Old Norse and Old English literature written down largely in Iceland and England between the ninth and the fourteenth centuries, in runestone inscriptions scattered across Scandinavia, in place-names that preserve the memory of older cults, and in the archaeology of ship burials, temple sites, and pagan amulets. They were not a single, fixed scripture but a living tradition that changed with each generation, each region, and each teller. The version that most modern readers encounter — the polished, sometimes Christianized, sometimes deliberately pagan account composed by the Icelandic chieftain and scholar Snorri Sturluson around 1220 — is only the most famous and most heavily edited corner of a far older and far more complex inheritance.

This page is the front door to the rest of the site. It maps the territory: who told these stories, where they wrote them down, what the principal gods and worlds are, how the Viking Age shaped the faith that produced them, what the major mythological themes are, and how a curious reader can navigate the deeper material collected in the rest of the site. Each section ends with pointers to dedicated pages where the topics are treated at full length.

What is Norse Mythology?

Norse mythology is the religion and narrative tradition of the pre-Christian North Germanic peoples. The term is modern — it was coined in the nineteenth century — and it covers a great deal of ground. At its narrowest it refers to the specific myths preserved in the two thirteenth-century Icelandic manuscripts known as the Poetic Edda and the Prose Edda. At its broadest it includes every story, deity, hero, creature, and ritual belief attested among the speakers of Old Norse and their linguistic cousins, from the Lapps of the Arctic to the Anglo-Saxons of pre-conversion England and the Goths who wandered as far as the Black Sea.

Three things distinguish the Norse tradition from its Indo-European relatives. First, it is unusually well documented. Few pagan religions of the early medieval world left behind the volume of literary, runic, and archaeological evidence that the North Germanic peoples did. Second, it survived unusually late. The conversion of Iceland in the year 1000, of Norway over the eleventh century, and of Sweden by the twelfth century means that the myths were still being recited, debated, and written down by people whose grandparents had been pagans. Third, the world it describes is bleakly beautiful — a cosmos under sentence of death, where even the gods know they will fall, and where the only honorable response is courage, kinship, and craft.

Geographically, the heartland of the tradition is Scandinavia — modern Denmark, Norway, and Sweden — together with the Viking colonies of Iceland, the Faroe Islands, Orkney, Shetland, the Hebrides, the Isle of Man, Greenland, and briefly Vinland (the Norse name for parts of North America). Mythologically related material also survives from Anglo-Saxon England (where the poem Beowulf is the crown jewel) and from continental Germany, where the Latin Gesta Hammaburgensis Ecclesiae Pontificum of Adam of Bremen, written around 1075, gives a remarkable outsider’s account of the great temple at Uppsala.

Chronologically, the mythic material itself is set in an imagined prehistory, but the written sources span roughly six hundred years. The earliest runestone that can be securely dated, the Hogganvik stone, was raised around the year 350 of the Common Era. The latest substantial mythological composition, the Rimur of Iceland, was still being written in the nineteenth century. The core of the tradition, however, is the Viking Age (c. 793–1066 CE) and the two centuries that followed it.

Indo-Europeanists, following the lead of scholars such as Jan de Vries and Einar Haugen, place the shared North Germanic inheritance as far back as the common Germanic period (perhaps 750 BCE to 200 BCE), while the specifically Scandinavian mythological material probably took shape during the late Iron Age and the Migration Period (c. 400–700 CE). The Viking Age, in turn, is the period in which the inherited material was crystallized, exported, and finally written down. A reader who keeps all three time frames in mind — the deep Indo-European past, the Iron Age world, and the Viking Age moment of recording — will find the tradition far more legible than a reader who treats it as a single static corpus.

The People Who Told These Stories

The myths were not the property of a single nation. They were shared, in different dialects and with local variations, by all the speakers of the North Germanic language family, a group that includes the ancestors of modern Icelanders, Norwegians, Danes, Swedes, Faroese, and the emigrant communities they founded.

The most important single community, however, was the Icelanders. Norway in the ninth and tenth centuries was a patchwork of petty kingdoms, and when political unification under Harald Fairhair (Old Norse Haraldr Hárfagri) made life uncomfortable for the regional chieftains, many of them packed their families and gods into open boats and sailed west to a large, empty, volcanic island in the North Atlantic. There, in the new Icelandic Commonwealth (c. 930–1262), they built a stateless society governed by an annual assembly called the Althing, and they remembered their pagan past with a vividness that mainland Scandinavia, under the political and religious pressure of Christian kings, gradually lost. Most of the written mythology we have comes from Iceland, and the two manuscripts of the Poetic Edda, the Prose Edda of Snorri Sturluson, the Heimskringla, the Völsunga saga, the Hervarar saga, and the great family sagas (Egils saga, Njáls saga, Laxdæla saga, and others) were all composed there.

The Anglo-Saxons, who spoke an early form of English and worshipped gods whose Old English names — Woden, Thunor, Frig — are the cousins of Óðinn, Þórr, and Frigg, left a different but related inheritance. The poem Beowulf in particular shares a deep mythological background with the Scandinavian tradition, including monsters, dragons, hero cults, and funeral ship-burials, even though it was written in a Christian era and a Christian kingdom.

The continental Germanic peoples — Goths, Vandals, Lombards, Burgundians, Franks — produced their own versions of the myths, but most of this material was filtered through the pens of hostile Roman and Greek historians (Tacitus, writing in the late first century, gives the famous account of the Germanic warrior Nerthus and the sacred grove of the Semnones) and was later overwritten by Christian missionaries. The exceptions are precious: the Merseburg Incantations, two small Old High German magical charms copied down in the ninth or tenth century, preserve fragments of pagan belief that are simply not found anywhere else.

The Norse, then, are the most visible, but not the only, voices in the tradition. A reader who wants the full picture needs to balance Icelandic literature, Anglo-Saxon poetry, German philology, and the archaeology of every place where pagans left their dead.

The historical Iceland of the tenth and eleventh centuries, where most of the surviving sources were written, is a society in fascinating transition. The settlers of the landnám period (c. 870–930) brought with them the cult of the Norse gods and the older tradition of the goði, a local chieftain-priest who led worship at a hof (temple) and acted as a kind of spiritual patron for his district. The goðar (plural) became the political and judicial leaders of the new Icelandic Commonwealth, and the old sacred functions merged with the new secular ones. Christianity arrived in the form of Irish and continental missionaries from c. 980 onward, and the matter was finally settled at the Althing in the year 1000, when the assembly voted, on the advice of the lawspeaker Thorgeir Ljósvetningagodi, that all Icelanders should be baptized while pagan worship might continue in private. The compromise was practical but unstable; within a century the goðar had become Christian, the hof had been dismantled or converted into churches, and the old gods had been pushed into the back rooms of memory and into the manuscripts of antiquarian writers.

That the myths survived at all is a small miracle. The principal reason is that by the time the old religion was politically dead, the Icelanders had already invented the book. The medieval Icelandic book-houses produced the Codex Regius of the Poetic Edda, the Prose Edda, the Heimskringla, the great family sagas, the Flateyjarbók, the Landnámabók, and a dozen other compilations that today form the spine of Old Norse studies. The codices were written on calfskin with quill and iron-gall ink, often in remote farmsteads by scholars working in the long winter nights, and the loss of even a single manuscript (such as the Völsunga saga in its lost manuscript, Nks 1824 b 4to, which perished in the fire of Copenhagen in 1728) can be measured in centuries of irrecoverable memory.

The Major Sources

Almost everything known about Norse mythology comes from a relatively small number of medieval texts, supplemented by a growing body of archaeological and runic evidence. The texts are the bones of the tradition; the archaeology and runology are the muscle and the skin.

The single most important manuscript is the Codex Regius of the Poetic Edda (GKS 2365 4to), a collection of twenty-nine anonymous poems written down in Iceland in the 1270s but preserving material that is often much older. The poems are arranged thematically: mythological lays such as Völuspá (the “Prophecy of the Seeress”), Vafþrúðnismál (the “Words of Vafthrudnir”), Grímnismál (the “Words of Grimnir”), Þrymskviða (the “Lay of Thrym”), and Lokasenna (the “Flyting of Loki”); heroic lays such as Völundarkviða (the “Lay of Wayland”), the Helreið Brynhildar (the “Ride of Brynhild”), and fragments of the Sigurd cycle; and didactic poems such as Hávamál (the “Words of the High One”) and Rígsþula (the “List of Rig”). Many of the poems preserve pre-Christian material in forms that are often older than the surviving manuscripts by three or four hundred years.

The second major source is the Prose Edda of Snorri Sturluson, written around 1220 and preserved in several manuscripts, the most important being the Codex Regius of the Prose Edda (GKS 2367 4to) and the Codex Wormianus (AM 242 fol.). Snorri was a Christian, and he wrote his book in part as a handbook for aspiring poets who wanted to compose in the elaborate Old Norse skaldic style, which depended on knowing a vast catalog of mythological names and kennings. The Prose Edda is divided into a prologue, the Gylfaginning (“The Beguiling of Gylfi”), the Skáldskaparmál (“The Language of Poetry”), and the Háttatal (“The List of Meters”). It is the most systematic account of Norse mythology that survives, and most of what the average modern reader knows about the Norse gods comes from Snorri — which is both a strength (he is clear, complete, and quotable) and a danger (he is sometimes inventing, sometimes euhemerizing, sometimes Christianizing, and sometimes copying older skalds whose names he has forgotten to mention).

The Heimskringla, also by Snorri and completed around 1230, is a history of the kings of Norway from mythological origins down to the year 1177. Its first section, the Ynglinga saga, is essentially a mythological genealogy: it traces the Swedish and Norwegian royal lines back to the gods of Asgard and gives a sometimes racy, sometimes cautionary account of how the divine ancestors behaved.

A fourth group of sources consists of the legendary and heroic sagas. The Völsunga saga (c. 1250–1270) is a prose retelling of the Sigurd legends that underlie the heroic poems of the Poetic Edda; the Hervarar saga preserves a different heroic cycle centered on the sword Tyrfing and the Goths; the Hrólfs saga Kraka and the Gesta Danorum of Saxo Grammaticus (written in Latin around 1200) cover the legends of the Danish royal house. The Gesta Danorum in particular preserves versions of the Hamlet story and a quite different, and probably older, account of the war-god Tyr that complicates the Snorrian picture in useful ways.

Beyond the literary sources, archaeology has become increasingly important. The discoveries of the Oseberg ship (1904), the Gokstad ship (1880), the Ladby ship (1935), the Tune ship (1867), and the Sutton Hoo ship-burial in England (1939) have shown that the funerary customs described in saga and eddic poetry were real and elaborate. The finds at Birka, Hedeby, Kaupang, and Ribe have mapped the trading towns where pagan and Christian worlds met. The great temple at Uppsala, described skeptically by Adam of Bremen, has been tentatively located near the royal mound of Old Uppsala, and its cult center has been partly excavated.

Runestones provide a third strand. About 2,500 runestones survive in Scandinavia, mostly in Sweden. Most are memorial stones raised in the eleventh century, after the Christianization of Sweden, and they use the Younger Futhark alphabet. A smaller, older group, the so-called Viking Age runestones, uses the Elder Futhark and dates from the period 160–800 CE. The mythological content of runestones is sparse but significant: the Mjølnir (Thor’s hammer) amulets are almost always late, and the rarer references to Odin’s name in inscriptions (for example, the Valsgärde buckle mounts) help anchor the cult of the Allfather in the archaeological record.

Among the most important runestones for the mythology is the Rök stone in Östergötland, raised by a father named Varin in memory of his son Vámóðr, in which a long inscription full of heroic allusions refers to “the war-band of the Hervarar” and seems to invoke the dynastic curse of the sword Tyrfing. The Stora Ramsjö stone in Södermanland contains a similar heroic allusion. The Karlevi Runestone on Öland (c. 1000 CE) is the only Scandinavian runestone to bear a complete stanza of skaldic verse, a memorial to a Danish chieftain named Esbjörn. The Snoldelev Stone near Roskilde (c. 900 CE) names the Skjald or poet, and the Gripsholm Stone (c. 1050) is the only one to use the word “Ragnarok” (or, more properly, the Old Norse Ragnarøkkr) in a runic inscription.

Finally, the place-names of Scandinavia are a vast, if fragmentary, source. More than a thousand place-names in Sweden and Norway incorporate the name of a god or a heathen concept — Torshälla (Thor’s hall), Odensala (Odin’s hall), Frösö (the island of the god Freyr), Mjölnir as a place-name — and they map the persistence of the pagan cult in particular regions long after the official conversion. The Swedish island of Frösö in Lake Storsjön in Jämtland, for example, was so named for the god Freyr and remained a cult center well into the Christian period. Place-name scholarship (ortnamn and namnforskning) is one of the most important tools of the field: it is often the only way to recover the cult of a god such as Ullr, who is almost invisible in the literary sources but survives in a dense web of place-names across Sweden and Norway.

The archaeology of the late Viking Age is also where one finds the clearest evidence of the syncretism between pagan and Christian practice. The baptismal names of the conversion period (such as Ásbjörn “divine bear,” Þorsteinn “Thor’s stone,” Guðrún “divine rune”) preserve the older names of the gods in the registers of Christian Iceland and Christian Norway. The runestone at Jelling in Denmark, raised by Harald Bluetooth c. 965, is a vivid image of the transition: it shows Christ being worshiped and carries an inscription in which the king boasts of having “made the Danes Christian,” and yet it is decorated with a Great Beast in the Mammen style that comes straight from the pagan iconographic tradition.

The Two Main Branches: Aesir and Vanir

The Norse gods are traditionally divided into two divine families, or pantheons, known as the Aesir and the Vanir. The distinction is one of the most important in the tradition, although it is also one of the murkiest.

The Aesir are the warrior gods of the sky. Their home is Asgard, the citadel of the gods, and their leaders are Odin, the Allfather of wisdom, war, and death; Thor, the thunderer, defender of Midgard and slayer of giants; and Tyr, the god of law and heroic honor. To the Aesir belong also Heimdall, the warder of the rainbow bridge; Baldr, the beautiful and doomed son of Odin; and the more ambiguous figure of Loki, a being of uncertain origin who lives among the Aesir as their blood-brother but whose children bring about the downfall of the divine order.

The Vanir, by contrast, are the gods of fertility, prosperity, the sea, and the earth. Their chief figures are Njord, the lord of the sea and the winds; his children Freyr and Freya; and a host of lesser beings associated with the soil, the harvest, and the erotic. The Vanir are older than the Aesir in the mythographers’ telling — they are the original inhabitants of Vanaheim, one of the nine worlds, and they practice a magic that the Aesir find both alluring and unsettling.

The two divine peoples, according to the Ynglinga saga and the Völuspá, went to war with each other in prehistoric time. The Aesir, unable to defeat the Vanir through ordinary combat, resorted to a kind of magical assault — striking them with weapons that broke the soil or hurling a captive into the Vanir host — and eventually sued for peace. The treaty involved an exchange of hostages: the Vanir sent Njord, Freyr, and Freya to the Aesir, and the Aesir sent the sage Mimir, whose head, after he was beheaded in the war, was preserved by Odin and used as an oracle.

The theology behind this myth has been variously interpreted. Some scholars (notably Georges Dumézil) read the Aesir–Vanir war as a mythologized reflection of an Indo-European contrast between two functions of society: a sovereign-warrior function and a fertility-cultivation function. Others, including many Anglo-Saxonists, see in the war an actual memory of religious conflict between rival cults in late Iron Age Scandinavia. Still others caution that the surviving texts are post-Christian and that the categories may be largely the work of Snorri, who liked tidy oppositions.

A full account of the Aesir and Vanir, with individual god-pages, is given in the Norse gods and the Aesir and Vanir overview.

A note on the interpretation of the war: the Völuspá (stanza 21–24), the Ynglinga saga (chapter 4), and the Skáldskaparmál all preserve versions of the war, and the three texts differ in telling ways. The Völuspá says only that the Aesir “shot” at the Vanir and that “their first war” began with this violence. The Ynglinga saga identifies the war as a prelude to the marriage of Freya and the blót of the tíund, and the Skáldskaparmál explains the war in terms of an Aesir-Vanir exchange of hostages and the origin of the practice of “the first war” in which the captured are sacrificed. The differences among the three accounts are themselves a sign that the older oral tradition was more variable and more open than the surviving written version, and that the categories of “Aesir” and “Vanir” themselves may have shifted considerably over the centuries.

The Cosmology

The Norse cosmos is a vertical structure, often pictured as a great tree. At its center stands Yggdrasil, the world ash, whose three roots reach down to three different regions: one into Asgard, the realm of the gods; one into Jotunheim, the land of the giants; and one into Niflheim, the realm of ice and mist. A squirrel called Ratatoskr runs up and down the trunk carrying insults, a dragon called Nidhogg gnaws at the lowest root, and a stags browses the highest branches.

The nine worlds of the Norse cosmos are arranged around the tree. The most important, for human beings, are Midgard, the world of humans, and Asgard, the world of the gods. Others include Jotunheim (giants), Vanaheim (the Vanir), Alfheim (elves), Svartalfheim (dwarves), Muspelheim (fire, home of Surtr), Niflheim (mist), and Helheim (the realm of the dead, ruled by a being of the same name). These worlds are not exactly parallel universes in the modern sense; they are more like overlapping zones of being, separated by rivers, seas, and dangerous bridges.

The moral and emotional center of the cosmology is the foretold end of the world, Ragnarok. According to the Völuspá, three winters of war will befall mankind (the Fimbulvetr, the “Great Winter”), followed by a chain of disasters: the wolf Fenrir will break free, the world serpent Jormungandr will rise from the encircling ocean, the fire giant Surtr will lead the sons of Muspel across the rainbow bridge, and the sky will split. In the final battle, Odin will be swallowed by Fenrir, Thor will slay the serpent and then walk nine paces before falling dead, Freyr will be cut down by Surtr, and most of the gods and their enemies will be destroyed. The world will sink into the sea and then rise again, green and beautiful, and a few surviving gods — Vidar, Vali, Modi, Magni, and the daughter of the sun — will inherit it.

The cosmology is treated at full length in the Norse cosmology and the nine worlds overview.

The Creatures and Other Beings

The Norse cosmos is famously crowded. Beyond the gods and the humans, the tradition recognizes a great variety of other beings, several of whom play decisive roles in the mythological plot.

The largest and oldest of these are the Jotnar — the giants, whose Old Norse name is the plural of jotunn. The giants are not simply large humans; they are an older, deeper, more elemental order of being, often associated with cold, stone, the sea, and the wild. Many of them are the parents or grandparents of gods (Odin himself is the son of the giant Borr and the giantess Bestla), and the wars between the gods and the giants are the engine of the mythic plot from beginning to end. Particular giants play crucial individual roles: Ymir, the primeval giant whose body becomes the world; Surtr, the fire giant of the end; and the sea-giant Aegir, who hosts the gods for beer.

The dragons of Norse myth are few but foundational. The world serpent Jormungandr, son of Loki, encircles Midgard and bites his own tail; the dragon Nidhogg gnaws at the root of Yggdrasil; the dragon Fafnir guards a treasure hoard in the Sigurd legend. The dragons are not merely monsters: they are the great cold-blooded opposites of the warm-blooded gods, the keepers of treasure and of the deep past.

The dwarves (Old Norse dvergar) are master smiths whose hands built Mjolnir, Odin’s spear Gungnir, the ship Skidbladnir, the boar Gullinbursti, the ring Draupnir, and the golden hair of Sif. They live in Svartalfheim and are sometimes conflated with the dark elves (svartalfar) of medieval sources. The elves are divided into light elves (ljósalfar) and dark elves (dökkalfar), the former radiant beings of great beauty, the latter subterranean and ambiguous.

Two other categories of being deserve mention. The valkyries are the choosers of the slain, the warrior-maidens of Odin who carry half of the honored dead to Valhalla — where they form the Einherjar, the army of the gods at Ragnarok. The valkyries appear by name in both eddic poetry and saga prose: Brynhild, Sigrdrífa, Sigrún, Sváva, and the rest. They pour the mead of the slain, they carry the heroes on their horses, and (in some later texts) they appear as lovers of mortal warriors. The Norns, three sisters named Urd (What Has Been), Verdandi (What Is Becoming), and Skuld (What Shall Be), spin the thread of every human life at the foot of Yggdrasil and water the tree from the well of Urd.

To these must be added the sea-being Huldra, whose name means “the hidden one” and who belongs to a broader class of seductive, often dangerous female beings — the huldrefolk — that surfaces more strongly in Scandinavian and particularly Norwegian folklore than in the older eddic material. Other minor beings include the landvættir (land-spirits) of the Icelandic law, the draugr (the undead of the sagas, who guard their graves and their treasures with a force that no living man can resist), the fylgjur (the personal spirits that follow each family in animal form), and the álfar of the Völuspá and the Hávamál. None of these has the cosmic stature of the Jotnar or the dragons, but each of them is a working part of the old worldview, and a complete account of the Norse cosmos is unimaginable without them.

A complete survey of these beings is given in the Norse creatures and beings overview.

The Heroes and Sagas

Alongside the gods runs a second current of story: the heroic. The Norse heroic tradition, sometimes called the matter of the North, parallels the matter of Troy or the matter of Britain, and it is preserved in two distinct but related bodies of literature.

The first body is the set of heroic poems in the Poetic Edda: Völundarkviða (the “Lay of Wayland the Smith”), Helreið Brynhildar (the “Ride of Brynhild”), the fragments of the Sigurd cycle, and a few shorter pieces. The second body is the prose heroic sagas, of which the Völsunga saga (c. 1250–1270) is the most important. The two are related but not identical; the prose sagas sometimes preserve older versions of the story than the eddic poems, and sometimes younger ones.

The central hero of the tradition is Sigurd the Volsung, the killer of the dragon Fafnir, the wielder of the broken sword Gram, the lover of the valkyrie Brynhild, and the doomed husband of Gudrun. The story of his acquisition of the cursed treasure of the dwarf Andvari, his murder by his brother-in-law Guttorm, and the long chain of vengeance that follows is told in detail in the Saga of the Volsungs. Specific moments from the legend, such as the slaying of Fafnir and the curse of the ring Andvaranaut, have their own dedicated pages.

The second great hero of the tradition is Beowulf, the Geatish prince who slays the monster Grendel (who is described in detail here), Grendel’s mother, and the dragon of his old age (whose fatal encounter is laid out here). Although Beowulf was composed in Anglo-Saxon England, its background is overwhelmingly Scandinavian, and the poem is the single longest piece of Old English verse to survive.

The third group of “heroes” is the legendary kings of Scandinavia: the Ynglings of Sweden, the Skioldungs of Denmark, the descendants of Halfdan the Black in Norway, and the dynasty of the earls of Orkney. Their deeds are told in the Heimskringla and the Orkneyinga saga, and they form a bridge between the divine and the historical.

A full treatment is given in the Norse heroes and sagas overview.

The Viking Age in Brief

The Viking Age is conventionally dated from the raid on the monastery of Lindisfarne on June 8, 793 — an event recorded by the Northumbrian chronicler Alcuin with the famous words “Heu, heu, heu — vindices, vindices” — to the battle of Stamford Bridge in 1066, where the English king Harold Godwinson defeated the Norwegian invader Harald Hardrada. In those 273 years the Scandinavians, using fast and flexible longships, transformed the political map of Europe. They founded the duchy of Normandy, settled the Danelaw in England, established the Kievan Rus’ along the rivers of what is now Ukraine and Russia, colonized Iceland, Greenland, and briefly North America, and raided as far as Constantinople, Baghdad, and the Mediterranean.

The religion that produced the mythology was the religion of the people who did this. To understand Viking warfare and battle tactics is to understand the cultural soil in which the cult of Odin and the rituals around Valhalla grew. To understand the role of Viking women — shield-maidens, seers, property owners, and family heads — is to understand the social context in which figures like the valkyries and the Norns were imagined. To understand the construction of a Viking longship is to understand the technology that carried the religion to every shore it reached.

Three institutions of the Viking Age are particularly important for the mythology. The first is the thing, the assembly of free men that met in each district and in each colony; the Icelandic Althing, founded c. 930, is the most famous. The second is the hird, the household of a king or chieftain, which doubled as a war-band and a school of poetry. The third is the cult of the ancestors, expressed in the long tradition of ship-burials, mound-burials, and cremations that the Oseberg and Sutton Hoo finds have so dramatically illustrated.

Two further points of context are worth underlining. The first is the role of slavery. The Viking Age economy depended heavily on the þræll (thrall), and the moral imagination of the sagas reflects this in interesting ways: the free man is the man who can carry a sword and own a thing-share, and the gods themselves are sometimes figured as the free men of a great cosmic thing. The second is the role of the blót, the sacrificial feast that bound the community to the gods and to the land. A blót typically involved the slaughter of an animal (often a boar, a goat, or a horse), the sprinkling of the participants with the hlaut (the blood of the sacrifice), the dedication of the meat, and a feast at which the gods were solemnly invoked by the goði. A blót at the great temple of Uppsala, attended by the king of Sweden every nine years, is described by Adam of Bremen with a mixture of horror and fascination, and the details of the ritual (nine victims of each sex and species, the bodies hung in the sacred grove) probably reflect an authentic late pagan practice.

Symbols, Runes, and Sacred Imagery

The Norse symbolic system is one of the most distinctive in the ancient world. It has two principal branches: the runic alphabets, used for everyday writing and for monumental inscriptions; and the pictorial and geometric signs used in art, jewelry, weapons, and amulets.

The runic alphabets form a family. The Elder Futhark, with twenty-four characters, was used in Germanic Europe from roughly the second to the eighth century. The Younger Futhark, with sixteen characters, gradually replaced it in Scandinavia from the eighth century onward, and a further reduction, the Hälsinge Runes or staveless runes, was used in some late Viking Age inscriptions. The Hagalaz rune ᚺ, the Tiwaz rune ᛏ, the Jera rune ᛃ, and the Sowilo rune ᛋ — to name a few — carried associations in addition to their sound values, and the surviving manuscripts, especially the Icelandic rune poems of the fifteenth and sixteenth centuries, attribute divinatory and magical meanings to almost every character. A practical introduction is given in the Elder Futhark reading guide.

The pictorial symbols are equally rich. Mjolnir, the hammer of Thor, was worn as a pendant by pagans and Christians alike well into the eleventh century, and small lead or tin Mjolnir amulets are among the most common pagan finds in late Viking Age Denmark. Other symbols include the valknut, three interlocking triangles associated with Odin and attested on picture stones and runestones; the triquetra, a three-pointed interlace knot more common in Insular Christian art than in Scandinavian paganism; the helm of awe (Ægishjálmur); and the Icelandic magical staves, a much later (and partly folkloric) family of signs that includes the vegvísir (wayfinder) and the stafur signs of the Galdrabók.

The art styles that carried these symbols — the Viking Age styles known as Broa, Oseberg, Borre, Jellinge, Mammen, Ringerike, and Urnes — form a continuous sequence from the late eighth to the late eleventh century, and the carved runestones, gold bracteates, and silver brooches of the period are the most accessible visual heritage of the pagan North. The Rök runestone in Östergötland, raised in memory of a son by a father named Varin around 870 CE, is the longest known runic inscription in the Younger Futhark and is full of allusions to heroic legend.

A complete treatment is given in the Norse symbols and runes overview.

From Old Myth to Modern Revival

The Old Norse myths never entirely died. Even in the centuries after the conversion, they were preserved in folk tradition, in nursery tales, in ballads, in the work of antiquarians, and in the continuing use of pagan place-names and personal names. By the early modern period a substantial body of learned knowledge about the myths had accumulated: the Icelandic Rímur continued to retell the old stories in verse; the Edda manuscripts circulated in learned circles; and scholars such as Snorri Sturluson were still being read by those with access to the libraries of Copenhagen and Uppsala.

The modern revival began in two waves. The first was the Romantic wave of the late eighteenth and early nineteenth centuries, when the discovery of the Elder Edda manuscript and the popularization of folk-poetry collections (the Kinder- und Hausmärchen of the Brothers Grimm in Germany, the Færøske Kvæder of V.U. Hammershaimb in the Faroes, the Norske Folkeeventyr of Peter Christen Asbjørnsen and Jørgen Moe in Norway) brought the old stories to a wide European audience. The second was the political and religious wave of the nineteenth and twentieth centuries, when the gods were recruited in turn by German nationalists, by Icelandic independence activists, by American and Scandinavian Heathens, and by popular culture.

The English-language reception begins with William Morris’s The Story of Sigurd the Volsung (1876), continues through the novels of J.R.R. Tolkien (whose legendarium is soaked in Norse influence, and whose own debt to the tradition is traced in a dedicated article), and explodes into popular culture with the publication of Norse myths in modern media, starting with Marvel’s Thor in Journey into Mystery #83 (1962) and continuing through video games such as God of War and Assassin’s Creed Valhalla.

The present-day religious revival goes by the name Heathenry or Ásatrú (an Icelandic compound meaning “faith in the Aesir”). It is a small, decentralized movement with congregations in Iceland, Scandinavia, Germany, the United Kingdom, the United States, and elsewhere. Its theology varies from a strict polytheism modeled on the textual Eddas to a more diffuse, nature-oriented spirituality; its rituals, when it has them, generally include blóts (sacrificial feasts) and sumbels (toast-drinking ceremonies). A full account is given in the Asatru and Norse Neopaganism entry.

A complete treatment is given in the Norse mythology in modern culture overview.

Major Themes in Norse Mythology

Norse mythology is not a corpus of arbitrary tales. It is a coherent (if incomplete) vision of the world, and the same small set of themes runs through the poems, the sagas, the runestones, and the law-codes.

The first and most pervasive is fate — the Old Norse urðr, related to the verb verða (“to become”) and the name of the foremost of the Norns. In the Norse view, the future is not open and not exactly closed: it is woven, and the weavers are the Norns at the foot of the world tree. Even the gods are subject to fate. Odin’s quest for wisdom is in part a quest to know what cannot be known; his gathering of the dead to Valhalla is a quiet preparation for the final battle that he knows he will lose. The Anglo-Saxon cognate of urðr is wyrd, and the related concept of wyrd is central to Old English poetry as well — Beowulf opens with a meditation on the deeds of the Scyldings and the way in which wyrd carries them all away. Fate in the Norse sense is not deterministic in the modern philosophical sense; it is more like a slowly-stiffening rope. The Völuspá shows the seeress remembering every prior event in the history of the cosmos; she does not, however, claim to control what comes next. The Norns themselves are the daughters of jötnar in some sources, which suggests that the power of fate is older than the power of the gods and outlasts it.

The second theme is honor. Honor (sæmd, virðing, or lof in Old Norse) is the social currency of the hero. It is won by brave deeds, by hospitality, by generosity, by loyalty to kin and lord, and it is lost by cowardice, by stinginess, by oath-breaking, and by kin-murder. The hero who dies well in the saga — Gunnar in the serpent pit, Grettir on his deathbed, Hallgerdur in her last speech — is honored; the hero who dies badly — Hrut in his lust, Fafnir in his avarice, Brynhild in her vengeance — is remembered with pity. The cult of the berserk and the cult of the god Tyr, who lost his hand to the wolf Fenrir for the sake of an oath, are two expressions of the same value. The Hall of the Slain in Valhalla is in part the warrior’s reward: the best of the slain get to fight and feast forever in Odin’s hall. But the cult of honor also has a darker side, and the nid, the ritual insult, can launch a feud that destroys three generations of a family. The Völsung cycle in the Völsunga saga is, in part, a meditation on the way in which the code of honor can be a trap.

The third is hospitality. The Norse code of hospitality is elaborate and well documented, and the sagas are full of long scenes in which the host offers the guest a seat, a cup, a bath, a night’s lodging, and gifts at the parting. The gods themselves are bound by this code: Odin and Loki travel together in Þrymskviða and in Gylfaginning; in the latter, they accept a giant’s hospitality and are received in a hall. The reverse of hospitality is the nid, a deliberate and public insult, and the great saga plots are often triggered by a breach of guest-right or a nid delivered at a feast. The Hávamál opens with advice to the wanderer: when you come to a strange hall, watch the floor, watch the door, watch the seat, and when you are offered a drink, take it. The poem’s long “Guest-rune” section gives detailed advice on how to behave at the table of a stranger, and the same advice, in slightly different form, can be found in the Völsunga saga and the Njáls saga. Hospitality in this sense is not a casual good manner: it is the social contract that holds the warrior aristocracy together.

The fourth is gift-giving. The exchange of gifts is the engine of the heroic economy, and the god most associated with it is Odin, who trades an eye for a draught of wisdom and receives the head of Mimir in exchange for the protection of the Aesir. The story of how Odin lost his eye is treated in its own right elsewhere. Gifts in the sagas are always public, always witnessed, always reciprocal. To give generously is to be kingly; to receive without return is to become a servant; to refuse a gift is an act of war. The act of gilding (the giving of a gild or payment) underlies much of the feud-system of the sagas, and the great scenes of gift-giving in the Njáls saga and the Laxdæla saga are the moments at which peace is made or unmade. In the eddic tradition, the giving of the ring Draupnir by Odin to his son Baldr, and the giving of the hair of Sif by Loki to Thor, are two of the foundational transactions of the divine world. Gift-giving in this sense is not generosity; it is the very grammar of social life.

The fifth and most distinctive is the doom of the gods — the conviction that even the gods are mortal, that the world they sustain is already falling, and that the only honorable life is a life that meets the fall with open eyes. This is the meaning of Ragnarok, and it is the meaning behind Odin’s gathering of the dead and Thor’s endless fishing trips with the world serpent. The doom is not, however, the end. After the fire comes the green earth; after the great winter, a new sun. The death of the gods is the precondition for the rebirth of the world. The doom theme is a special case of a more general Norse interest in doom as a category — dómr in Old Norse covers everything from a legal judgment to the final sentence of the cosmos. The doom of the gods is sometimes read as a Christian contamination of the older pagan myth (in which case it would be a sign of how thoroughly Snorri and his sources had been re-shaped by a thousand years of Christian thought), and sometimes as a deep, distinctive, pre-Christian Norse contribution to the religious imagination of Europe. The truth is probably somewhere in between, but the doom is real, the texts are clear, and the people who originally told these stories appear to have believed what they were saying.

The sixth and final theme is the cycle of death and rebirth. The world is destroyed and rebuilt, the sun is replaced by her daughter, the surviving gods walk in a green new land, and a pair of human survivors — Líf and Lífþrasir — emerge from Hoddmímis holt, the “wood of Hoddmimir,” to repopulate the earth. The cycle appears not only in the great cosmic drama of Ragnarok but in the smaller cycles of daily and seasonal life: the dying-and-rising god Baldr, whose death is a kind of prefiguration of the greater death; the cult of Freyr, whose midsummer festivals celebrated the harvest and the marriage of heaven and earth; and the sitting-out of Yule, in which the new year was welcomed with feasting, oath-taking, and the sacrifice of a boar. The cycle is the deepest pattern in the tradition. The myth of the death and the mourning of Baldr is the most concentrated expression of it, and the question of why Baldr’s death was inevitable is treated on a dedicated page. In some readings, the myth of Baldr is the prototype of the entire eschatological drama: the bright god, the loving father, the murder by mistletoe, the failed attempt to retrieve him from the realm of the dead, the coming of the greater end.

These themes are not abstract. They are carried by the gods and the heroes, by the words of the eddic poems and the deeds of the sagas, and by the shape of the world tree and the design of the runestones. A reader who comes to the tradition for the first time should keep them in mind, because they are the lens through which the older texts make sense.

How to Read These Pages

Each page on this site is written to be readable on its own and to be cross-linked to its neighbors. The Norse poets had a word for a poem that stands on its own and a word for a poem that calls out to its kin; the modern web is a place where both kinds of poem can live side by side.

For a reader who is new to the tradition, a reasonable path through the site is to start here, then move to the cosmology, then to the gods, then to the heroes, then to the creatures, then to the Viking Age context, then to the symbols, and finally to the modern afterlife. For a reader who already has a favorite — say, the saga of Sigurd or the figure of Loki — every cluster and long-tail page is self-contained and includes the “Related Topics” links at the bottom to navigate outward. The “Further Reading” section just below offers the most reliable English-language editions of the principal primary sources.
