Marbendill, the threefold laugh of the merman
By Ralf Ittermann · last reviewed on
Marbendill is a spirit of the Germanic/Nordic tradition.
Once caught, he laughs three times and reveals hidden truth. Marbendill is known from Icelandic sagas as a merman who laughs three times when caught.
As an Icelandic water spirit, the Marbendill is merman and soothsayer at once. Fishermen pull him from the sea; whoever sets him free is richly rewarded.
He is known for his threefold laugh, which each time brings a hidden truth to light.

The catch, the laugh and the reward
The Landnámabók of the 12th century tells of a caught, prophesying marmennill. Jón Árnason collected the best-known version: a farmer carries a captured Marbendill homeward, who laughs three times, when the dog is struck, when he stumbles over the cursed hill, and when he embraces his wife. Only after the promise of release does he name the reasons: joy, treasure, infidelity.
From proverb to legend motif
That the Marbendill laughed became proverbial in Iceland for a sudden, mocking burst of laughter. He belongs to the type of the captured being who grants a blessing in exchange for release, a tale about insight and self-deception.
