I.33 is the oldest known fechtbuch. It was written in Germany around 1300 and is now kept at the Royal Armouries in Leeds. Its author, a cleric named Lutger, presents a sophisticated tactical approach for unarmoured combat with sword and buckler. Curiously, the manuscript also includes depictions of a mysterious fighting woman named Walpurgis. I.33 is DIMICATOR's main source for historical swordsmanship. Learn more at this website:
