The Myth
The Brunnmigi is a large, foul creature associated with the defilement of wells. Its name means “well-pisser,” reflecting its infamous habit of contaminating sources of drinking water. The creature appears in a tale involving King Hjörleifr, who encounters it during his adventures. Although its precise appearance is not described, the Brunnmigi is portrayed as a large beast whose presence threatens the cleanliness of wells and the water upon which people depend.
The Brunnmigi is also associated with foxes, as the name appears as a poetic term for these animals. This connection links the creature to the fox’s place in Norse tradition, although the Brunnmigi’s identity and its relationship to ordinary foxes remain unclear. Its defining characteristic is its association with polluted wells, making it a strange and unpleasant beast remembered for its distinctive behaviour.
