The Wager and the Short Haft

After Loki shears Sif's hair, he must replace it, and from the sons of Ívaldi he commissions hair of living gold, the ship Skíðblaðnir, and the spear Gungnir. Swaggering, he wagers his head with the dwarf Brokkr that Brokkr's brother Sindri cannot make three finer treasures. At the forge, Loki becomes a fly and bites Brokkr at the bellows — arm, then neck, and Brokkr does not falter; but the third bite lands on his eyelid, and blinded by his own blood for one stroke of the bellows, he mars the work. Out of the forge comes a hammer — with a haft too short (Skáldskaparmál, trans. Brodeur).

Brokkr names its virtues to Óðinn, Þórr, and Freyr: swung, it never fails; thrown, it never misses; it returns to the hand of its own will; and it shrinks small enough to be kept inside the shirt. Only the short haft is held against it — and the gods judge it the best of all six treasures, 'for with it Þórr can defend us against the mountain-giants.' Loki, defeated by the very sabotage he taught, keeps his head only by a trick. The myth means the flaw in the gods' most trusted tool is the permanent signature of the adversary's interference.

The Hammer in the Bride's Lap

Þórr wakes one morning and the hammer is gone. Loki borrows Freyja's falcon-shape, flies to Jötunheimr, and hears Þrymr boast that he has buried Mjǫllnir eight leagues down — and that no one recovers it unless Freyja is brought to him as bride. Freyja's refusal shakes her hall and snaps the necklace Brísingamen, so Heimdallr proposes the unthinkable: dress Þórr as the bride. The thunder-god protests — until Loki answers that without the hammer the giants will soon hold Ásgarðr. Veiled, hung with Brísingamen and jingling keys, Þórr rides east with Loki as his maidservant (Þrymskviða).

The comedy is exact: the 'bride' devours an ox and eight salmon and drains three casks of mead, while Loki explains to the startled groom that Freyja has eaten nothing and slept not at all for longing. Þrymr lifts the veil for a kiss and leaps the hall's length from the fire in her eyes. Then he calls for the hammer — to hallow the bride, laid on her knees by the hand of Vár — and Þórr's heart laughs in his breast. His hand closes on the haft; he kills Þrymr, then the giant's whole household. The joke has a hard core: the hammer laid in the bride's lap is not a stage prop but the consecration itself — and the mightiest of the Æsir must wear bridal linen to recover his own.

Hrungnir and the Whetstone

The hammer's most dangerous duel came against the giant Hrungnir, who boasted in Asgard itself that he would kill all the gods, carry Freyja and Sif off to Jötunheimr, and drain the Æsir's ale. The gods sent for Þórr, and at the ford of Grjótúnagarðar the giant waited behind his stone shield, hurling his whetstone weapon. Mjǫllnir and the whetstone met in mid-air: the hammer smashed the stone and drove on into Hrungnir's skull — but a shard of whetstone lodged in Þórr's own head. The god walked home with the fragment still in him, and the sorceress Gróa was summoned to sing it loose. Her spells worked; Þórr felt it stir, and in his joy told her that her long-lost husband was on his way home — Gróa forgot her charms mid-verse in her delight, and the whetstone stayed in Þórr's skull forever. Snorri adds the custom: whetstones are forbidden as grave-goods, for this reason. The myth means the hammer's victories are never clean — its greatest triumph left its bearer permanently scarred, and the one thing Mjǫllnir could not fix was the wound it won by.

Hallowing Baldr's Pyre

When Baldr lies dead, the gods build his pyre on the ship Hringhorni, and the giantess Hyrrokkin, riding a wolf with vipers for reins, must be fetched to launch it. Baldr's wife Nanna dies of grief and is laid beside him. Þórr steps forward and hallows the pyre with Mjǫllnir — the god of thunder blessing the burning of the best of the gods — and when a dwarf named Litr runs across his path, he kicks him into the flames (Gylfaginning). The same gesture revives his slaughtered goats after they have been eaten, hallows the bride at the wedding feast, and here blesses the grave. Hammer at the cradle, hammer at the marriage-bed, hammer at the pyre: Snorri's picture of Þórr is of a god whose weapon marks every threshold of life — destruction and consecration in one motion, never separated. The Viking-age custom of wearing the hammer at the throat simply hung that threshold-power around the neck.
