‘This discussion by Sigurður Gylfi about Magnús Hj. Magnússon is great fun. As I have said, I like the methodology and the material is such that readers all over the world must be impressed, feel sorry for Magnús, admire him and despise him at the same time. I find Sigurður Gylfi's theory that Magnús created a character, a version of himself, that over time has begun to influence his perception, views on the world and how he organized his life, particularly interesting. Thus, the diaries are not only a source of Magnús agency, but an act in itself, a testimony that he was a doer in his own life, "a man who responds to his fate", but this is the unanimous conclusion of Sigurður Gylfi.’ - Ásta Kristín Benediktsdóttir, Saga LIX:1 (2021).
