I think the problem with You are not allowed to view links. Register or Login to view. and You are not allowed to view links. Register or Login to view. marginalia may be simply in that they are in some Germanic dialect which is not very well documented, at least in the sources we use. E.g. suppose the last plaintext letter in You are not allowed to view links. Register or Login to view. is "c", not "a". It's really difficult to distinguish. If "c", then the second part of the word can be read as suspiciously "German-looking" "munic", and the whole word - as "vullmunic".
"Munic" is something in between "Moench" and "Munich"
, but (for the only path that I explored) checking "mun" in Lexer leads to "muegen", and the latter seems (the article is difficult for me to follow) to relate to "Moeglichkeit", so with "vull" as "voll", "vullmunic" may stand for something like "omnipotent" or "allmighty". Just speculation, of course, but it shows possible diverse ways that dialects of the 15th century can take.
