Magni is the god of raw strength in Norse mythology, the son of the thunder god Thor by the giantess Járnsaxa. His name means "the mighty," and the sources show him living up to it while still a small child — lifting a weight no other god could budge and surviving the ruin of the gods to carry his father's hammer into a new age.
Who is Magni?
Magni belongs to the younger generation of the Aesir, a son of Thor set apart by sheer physical power rather than any craft or wisdom. Snorri Sturluson names him alongside his brother Móði as heirs to Thor, and the poem Vafþrúðnismál foretells that the two brothers will possess Mjölnir once their father has fought his last battle. Where Thor's strength is a god's, Magni's is a marvel even among gods, evident from the very earliest days of his life.
Magni and the giant Hrungnir
Magni's defining feat comes in the tale of Thor's duel with the giant Hrungnir. Thor shatters the giant's whetstone weapon and kills him with Mjölnir, but as Hrungnir falls his enormous leg drops across Thor's neck and pins him fast. None of the assembled Aesir can lift it. Then Magni — only three nights old — strides up and heaves the leg aside, freeing his father, and remarks that he would have felled the giant with his bare fist had he only been asked. Thor, delighted, rewards his son with Hrungnir's swift horse Gullfaxi, "golden-mane."
Magni after Ragnarök
Most of the great gods are fated to die at Ragnarök, Thor among them, slain by the venom of the world-serpent even as he kills it. But the destruction is not total. Magni and Móði are named among the survivors who inherit the renewed earth, and to them passes Mjölnir, the hammer that guarded the worlds. In this way Magni carries his father's strength — and his father's weapon — forward into the world reborn.
Symbols and legacy
Magni is strength itself, the plain and overwhelming force that shifts what cannot be shifted. He stands close to his half-sister Þrúðr, whose name also means "strength," within Thor's line of power. His nature answers to the rune Uruz, the wild ox of primal vigour and endurance, and his survival of Ragnarök makes him a quiet emblem of strength outlasting even the end of the world.
