Thor

← Encyclopedia

Thor (Old Norse Þórr) is the Norse god of thunder and the sky’s violence, remembered above all as the wielder of the hammer Mjǫllnir and the tireless defender of gods and humans against the giants. His name is the word for thunder itself; the rumble of the storm was understood as his chariot, drawn by two goats, crossing the heavens.

What the surviving texts say of him comes mostly from thirteenth-century Iceland — the poems of the Poetic Edda and the handbook Snorri Sturluson compiled to preserve the old verse-craft — written down two centuries after the North had converted to Christianity. In these sources Thor is the son of Odin and of Jǫrð, the Earth; red-bearded, enormous, quick to anger and prodigious in eating and drinking. The stories set him again and again against the jǫtnar, the giants who press on the ordered world from outside: he fishes for the world-serpent Jǫrmungandr, recovers his stolen hammer by disguising himself as a bride, and is fated at the world’s end, Ragnarǫk, to kill the serpent and die of its venom in the same moment. Where Odin is the god of poets, kings, and cunning, Thor is the protector — the one a farmer or a sailor actually called on.

That distinction matters for what scholarship can establish. Place-names across Scandinavia carry Thor’s name far more thickly than Odin’s, and the small hammer-shaped amulets found in pagan graves suggest a cult that reached ordinary people broadly and deeply. By the standard reckoning of the evidence, Thor, not Odin, was the most widely venerated of the Norse gods in the last pagan centuries. The weekday Thursday — Old English Þunresdæg, “Thunor’s day” — preserves the wider Germanic form of the same god, named in the Roman habit of matching foreign gods to one’s own: Thunor’s day stands where Latin set the day of Jupiter, the sky-father and thunderer. The equation is old and revealing, and it is not identity; the storm-god of the Germanic farmstead and the supreme god of the Roman state were never the same figure, only recognisable to each other.

What worshippers themselves believed is harder to recover than the myths, since the myths were written by Christians ordering a memory. The amulets and the place-names, the oaths sworn on his ring, the carved hammers raised over graves point to a god trusted for protection — over the harvest, the journey, the boundary against chaos — rather than contemplated as a mystery. The hammer that later hangs at a Christian’s neck began as the thing that kept the giants out.
