Also called Grim, Strömkarlen, Näcken (a Swedish cousin).
The tale
The fossegrim is a young man who sits under waterfalls and mill races playing the fiddle so wonderfully that trees dance and waters stop to listen. A fiddler who wants to learn from him must bring a white kid goat, or smoked meat, on a Thursday evening, throw it into the falls with his face turned away, and ask for teaching. If the offering is fat and generous, the grim takes the player's hand and moves it along the strings until the fingers bleed, and afterwards he can play like the grim himself. If the gift is thin, the fiddler learns only to tune his instrument and never to play it.
Their day
Thursday. Norwegian tradition says the gift to the fossegrim should be made on a Thursday evening.
