Eine noch unbekannte Geheimschrift in der Korrespondenz zwischen Ambrosius Blarer und Heinrich Bullinger (1546–1553)

After the outbreak of the Schmalkaldic War in July 1546, Heinrich Bullinger, the reformer of Zurich, and Ambrosius Blarer, the reformer of Constance, occasionally corresponded in cipher. They did so over a period of about seven years, with peaks in the years 1546, 1547, and 1548. The secret code they used might also occur in other archival material. This article offers the key for deciphering this code and analyses its use. The compromising nature of the information transmitted moved Blarer especially to turn to cipher in order to protect himself as well as other people.
