Freischütz (i.e. Freeshooter), a legendary hunter who made a compact with the devil whereby of seven balls six should infallibly hit the mark, and the seventh be under the direction of the devil, a legend which was rife among the troopers in the 13th and 14th centuries, and has given name to one of Weber's operas.
