The Cgm 558, or Codex germanicus monacensis, is a convolution of two 15th-century manuscripts with a total of 176 folia, bound together in the 16th century. It is kept at the Bavarian library in Munich. The first manuscript contains two chronicles composed by one Otmar Gassow in 1462, one concerned with Zürich, the other with the Toggenburg (see Old Zürich War), and a copy of the 13th century Schwabenspiegel law codex.
