Iceland is protected by four great guardians
According to a saga in Heimskringla a king of Denmark, King Harald Bluetooth Gormsson intending to invade Iceland, had a wizard send his spirit out in the form of a whale to scout it out for points of vulnerability. Swimming westwards around the northern coast, the wizard saw that all the hillsides and hollows were full of landvættir.
He swam up Vopnafjörður, intending to go ashore,
but a great dragon came flying down the valley toward him, followed by many snakes, insects, and lizards, all spitting poison at him. So he went back and continued around the coast westward to Eyjafjörður, where he again swam inland. This time he was met by a great bird, so big that its wings touched Breiðafjörður.
There he was met by a huge bull, bellowing horribly, with many landvættir following it.The bull (Griðungur) in the west |
The giant (Bergrisi) in the south. |
