In the 15th century, an anonymous author wrote a commentary on the fencing art of Johannes Liechtenauer. This commentary would spawn three distinct yet similar lineages of the tradition, which we now refer to as the Ringeck, Danzig, and Lew branches. In the modern practice of historical longsword fencing, these three texts are among the most widely practiced and studied historical sources. This book includes translations of these three branches side by side. It is intended to be useful for all students of the art, from the beginner trying to delve into the sources for the first time, to the advanced practitioner interested in comparing the nuances of each branch.
