The catalog form `De Veris Principiis Artis Dimicatoriae` restores spacing and modernizes the ligatured ending used in some witnesses.

Castle also records the Wittenberg 1579 Gunterrodt witness.
Vigeant 1882 preserves the 1579 Wittemberg witness of Gunterrodt's Latin fencing treatise and notes that some authors instead report Venice as the place of printing.
