Source notes

Schickard, a friend of Kepler’s, designed this “astroscopium,” a model intermediate between a planisphere and a celestial globe, to calculate the positions of the stars for any day and hour of the year. 

Schickard also devised a calculating machine to produce astronomical tables according to Kepler’s laws.

The constellations in Shickard's Astroscopium identify the constellations with biblical characters, in addition to the commonly accepted ancient names.
