What it is
Fossegrim is a figure from Scandinavian folklore who dwells in rushing water. He appears as a man playing a fiddle near streams and waterfalls. The name comes from words meaning waterfall and mask. He is linked to other water spirits like Nokken. People believe he possesses great musical talent that can be shared with humans.
Where it comes from
The spirit belongs to Norwegian and Swedish traditions. In Sweden, he is called Strömkarlen. He is sometimes confused with Näcken. Some tales link him to mill spirits called kvernknurr. These stories show how people viewed the power of nature through supernatural beings.
How it is done
To learn music, one must make an offering on Thursday night. The gift is thrown into a north-flowing waterfall. It can be a white goat or smoked mutton. If the offering is good, the spirit teaches the tune by drawing fingers across strings until they bleed. Poor offerings result in only basic tuning lessons.
Tools and materials
The main tool is a fiddle. Offerings include a white he-goat or smoked mutton called fenalår. The goat must have its head turned away. The meat must be substantial enough to satisfy the spirit. These items are placed in flowing water at night.
