Not before their successor, the “Beizbüchlein”, was published as the very first printed book on hunting in Europe, the so-called “Habichtslehren” (“goshawk-lore”) got to some publicity and made quite remarkable impact on the development of a widespread and highly relevant cultural technique of medieval society. The work at hand closes many gapes in research by editing the three known German manuscripts newly resp. for the first time, but also translating and extensively annotation them. Moreover the question asked since the 1960s on the origin of these texts in the German dialect´s landscape can be answered coherently. A comprehensive description of the guild-bound “falconer’s language” forms the third part of this volume.
