Kopakonan, also known as the Seal Woman, is a legendary creature in Icelandic folklore. The story goes that a young fisherman named Þorvaldur met a beautiful woman on the shore, and they fell in love and got married. The woman was a seal, and Þorvaldur promised never to reveal her true identity. They had children and lived happily together for several years, but one day Þorvaldur broke his promise and told others about his wife's true form. The seal woman was devastated and returned to the sea, leaving Þorvaldur and their children behind.

The story of Kopakonan has been passed down through generations in Iceland and is often used as a cautionary tale about the consequences of breaking promises and betraying trust. In recent years, a statue of Kopakonan has been erected in the town of Mikladalur in the Faroe Islands, depicting the mythical creature rising from the sea with a child in her arms. The statue has become a popular tourist attraction and symbol of Nordic folklore.
