A farmer kept a sow but had no boar. Despite this, the sow became pregnant and had piglets every year. One day the sow was seen running eastwards through Viðareiði and down towards a small bay. One of the women in the village got a hold of it and hastily tied a bundle of keys to its tail. The sow then ran into the sea and swam away. A moment later an island was seen drifting from the south. The villagers quickly manned a boat and rowed to the island. Since the sow had iron keys attached to its tail, it fastened to the seabed. Ever since the island has been called Svínoy (Pig Island).
