Linz: Johannes Planck, [1617-19]; Sagan: for the Author, 1630 E15000-25000 FIRST EDITION of Kepler's tables of sequential planetary positions over time based on the Tabulae Rudolphinae, or perpetual tables for calculating planetary positions, that he had undertaken as imperial mathematician to Rudolph II. "Eager to reap the fruits of his own astronomical tables, he set to work calculating ephemerides. In this he was assisted by Jacob Bartsch, a young scholar who had studied astronomy and medicine at Strasbourg and who calculated the positions for 1629-1636. Ephemerides pars III (1629-1639) was printed first, then the second part (for 1621-1629), which also contained Kepler's daily weather observations. (The first part, for 1617-1620, had been printed year by year at Linz)"-DSB VII, 306. Caspar 52, 84; Honeyman sale 1793 ("complete sets of Kepler's Ephemerides are extremely rare"; Zinner 4594, 5187.
