 Most of the sources for Myllarguten's life were written down from living memory, accounted by people who had met the fiddler, and his close relatives.Other sources exist as articles by romantic nationalists in Norway, who met the fiddler and described him.All the material was collected and edited by the folklorist Rikard Berge, himself from Telemark, and grandson of Rikard Aslaksson as mentioned above.
