The mathematician Ferdinand Czadeczky of Chotiessow lived in 1676 in the Praemonstratenzer cloister ‘Monasterii Zabrdovicensis’. (Nowadays Zábrdovice is a part of the city of Brno in the Czech Republic). He had a profound interest in astronomy . In 1715 for instance Czadeczky engraved a celestial tableau calculated for the polar height of Brno. A few years before (in 1709) he had started an annually published almanach, called Titular-Kalender, containing astronomical information. This almanach was continued to be published far into the 18th century (Golvers, Verbiest, 2003, 416-417). In 1715 Czadeczky moved to Prague, where he lived as a ‘Prämonstratenser Chorher’" (Louwman and Zuidervaart, 2013).
