"Discus Chronologicus, in quo Omnes Imperatores et Reges orbis Europaei a nato Christo ad praesens tempus…", Weigel, Christopher

Ingenious chart in the form of a dial with a moving pointer, providing a chronology of the Holy Roman Emperors, Popes and kings of Europe from AD to 1721. The names of the noblemen appear in fourteen concentric rings, one for each title, with 20 degrees for each century. The titles appear at the appropriate positions on the pointer, so that one can turn the pointer to any date to see the names of the noblemen at that date. The separate rotating pointer is completely original and in perfect condition. Cherubs hold the drape style title at top and there is a textual explanation at bottom. This unusual chart was issued in some copies of Johann David Köhler’s undated school atlas, Atlas Scholasticus et Itinerarius, and separately listed in his 1724 Anleitung zu der verbesserten Neuen Geographie.
