The Cantonal Secretary of Schwyz Hans Fründ († 1469), originally
from Luzern, wrote a chronicle of the Old Zurich War in about 1447.
This carefully written copy illustrated with the flags of the
cantons of the Confederation was made by Rorschach chaplain and
former Schwyz schoolmaster Melchior Rupp in the year 1476. The
manuscript, in the final pages of which are transcribed certain
records and documents from the years 1446 through 1450 related to
the Old Zurich War, made its way into the possession of Glarus
scholar Aegidius Tchudi (1505-1572) and from there, in the year
1768, into the Abbey Library of St. Gall.
