Schwabenspiegel
The Schwabenspiegel is a legal code, written in ca. 1275 by a Franciscan friar in Augsburg. It deals mainly with questions of land ownership and fiefdom, and it is based on the Pentateuch, Roman law as well as Canon law. It draws on the early 13th century Sachsenspiegel, and is immediately dependent on the Deutschenspiegel code.
The name "mirror of the Swabians" is also taken from the Sachsenspiegel ("mirror of the Saxons"). Since the code is not prescriptive but descriptive, i.e. it records current legal practice, it does not impose any new laws, it was metaphorically compared to a mirror in which to perceive right and wrong.
