where the memoir of the chancellor François Gurnel and the chronicle of Franz Rudella
provide insights not available from other sources. An exemplary analysis of the pitfalls of

- Although the archives of several of the Hegau noble dynasties survive and have been
catalogued by Helmut Maurer, they contain for the most part family papers, estate records,
and the like. There is, alas, almost no material relating to their involvement in the political

archives is by no means straightforward.
