The Merman of Þistilfjörður

Þistilfjörður, Northeast Iceland

In 1420, a creature half-man and half-fish was captured in a net in the Þistilfjörður fjord, kept alive for three days during which it was observed to weep, and released on the orders of the local bishop.

The account of the Þistilfjörður merman is preserved in Icelandic ecclesiastical records from 1420 and is considered one of the most detailed firsthand accounts of a merfolk encounter in European history. Fishermen working the northeast fjord brought up a creature in their nets that was, from the waist up, indistinguishable from a pale, dark-haired man. From the waist down, it was fish. The fishermen, rather than killing it immediately as was common practice for unusual catches, brought it ashore. The creature was kept for three days in a water-filled pen constructed for the purpose. During this time it was observed by the bishop's representative, who compiled the ecclesiastical report. The creature did not speak. It ate raw fish when provided. It slept. On the second day it wept — described in the record as 'true tears, as a man weeps, not as an animal expresses distress.' The bishop, on receiving the report, ordered the creature returned to the sea. His reasoning, recorded carefully, was that if it could weep it had a soul, and if it had a soul it was not his place to keep it captive. The fishermen complied. The creature was released at the same location where it was caught. It did not surface again. The fjord has a long subsequent history of unusual net catches: objects of unknown material, bones of animals not found in Icelandic waters, and, twice in recorded history, pieces of net that had been cut cleanly from the outside.
