Eva, he's still left a lot more to posterity than many others
Although I appreciate your input, for you, as a fellow native Scandinavian, I think it's a lot easier to make sense of my rendering than it might be for eg. an American who lacks our cultural background.
For instance, Svend had his legal capacity revoked due to insanity. The term is "umyndiggjort" in Norwegian, and I believe that the corresponding Swedish term is "omyndigförklarat". I don't know if there's an exactly corresponding word in English, but I figure that "legal capacity revoked" and "legal minor" are close.
