We have three authors named in the manuscript, Hermann von Sachsenheim, Erhard Wameshafft and Schoffthor. The last one remains just a name to us (an aptronym, denoting a writer as foolish as a sheep). But the other two give important clues for the world around the manuscript.
Read about Hermann von Sachsenheim.
