Thor is the Norse god of thunder, storms, and strength, and the tireless defender of both gods and humans against the giants. Son of Odin and the earth goddess Jord, he embodies the raw power of the sky and the honest courage of the warrior. His name has thundered across the Germanic world for more than two thousand years.
Who is Thor?
Among the Aesir, Thor stands as the great protector. Where Odin governs through wisdom and sacrifice, Thor defends through action and force. He patrols the borders of Asgard and rides through Midgard to destroy the giants and serpents that threaten the ordered cosmos. Despite his enormous strength, the myths consistently portray him as straightforward and loyal rather than cruel, a quality that made him the most widely worshipped god among ordinary Norse farmers and seafarers.
Origins and the name
Thor's name derives from Old Norse Þórr, tracing to Proto-Germanic Þunraz, meaning the thunderer. In Old English he was called Thunor, and his name survives in Thursday, from Þūnresdæg, Thunor's day. The Continental Germanic peoples knew him as Donar. The Romans equated him with Hercules as a mighty champion, and sometimes with Jupiter as ruler of the sky. Thor is attested across the Poetic Edda, the Prose Edda of Snorri Sturluson, skaldic verse, runic inscriptions, and Scandinavian place-names preserving the element Tor- or Thor-.
Myths and stories
Three myths stand out as defining encounters. In the Hymiskvida, Thor rows to sea with the giant Hymir and casts a line baited with an ox head to fish for the world serpent Jormungandr. He hauls the monster to the surface and the two gaze at each other across the gunwale, but Hymir cuts the line before Thor can strike. They are fated to meet again only at Ragnarok.
In Thrymskviða, the giant Thrym steals Mjolnir and demands the goddess Freya as ransom. The gods refuse, and Loki devises a plan: Thor will dress as a bride and enter the giant's hall to recover the hammer. Thor plays the role badly, devouring an ox and eight salmon at the wedding feast, but the ruse holds long enough for Mjolnir to be placed in his lap during the blessing ceremony. He seizes it and kills every giant in the hall.
In the Utgarda-Loki episode from the Prose Edda, Thor fails three apparently simple tests: he cannot empty a drinking horn, lift a cat, or pin an old woman in wrestling. The giant king reveals afterward that the horn was connected to the sea, the cat was Jormungandr in disguise, and the old woman was old age itself. Even his apparent failures reveal his immense power.
Symbols and attributes
Thor's hammer Mjolnir, forged by the dwarves Sindri and Brokkr, is the most important sacred object in Norse religion. It never misses its target and always returns to Thor's hand. To wield it he wears iron gloves called Jarngreipr and the belt Megingjord that doubles his strength. His chariot is drawn across the sky by two goats, Tanngrisnir and Tanngnjóstr, which he can slaughter for food and resurrect the next morning provided no bones are broken. The Thurisaz rune, whose name relates to giants, is linked to Thor in modern rune practice, though this association is not attested in the primary sources.
Family and relationships
Thor is the son of Odin and the earth goddess Jord, making him the most directly earthly of the Aesir. His wife is the golden-haired Sif, a goddess associated with grain and the harvest. His companion on many adventures is Loki, whose clever tongue compensates for what Thor lacks in subtlety. The relationship is often strained: Loki's schemes create the very problems that Thor must solve, sometimes violently.
Thor at Ragnarok
At Ragnarok, Thor's fate is bound to Jormungandr. The two have circled each other through the entire mythological age, and the final battle brings them together at last. Thor kills the world serpent with Mjolnir, then takes nine steps and falls dead, overcome by Jormungandr's venom. Nine is a sacred number in Norse cosmology, and nine steps carry the weight of a final, completed act.
Worship and legacy
Thor was the most universally worshipped of the Norse gods, invoked for protection, good harvests, and safe voyages. Miniature Mjolnir amulets appear across Scandinavia and are among the most common Viking Age finds. Thursday preserves his name in all Germanic languages. In the modern Heathenry and Asatru movements he remains a central figure of devotion, and the Marvel films brought his name to a global audience.
