hominisaevum:

Calendarium and ephemerides by Joannes Regiomontanus (1436-1476)

Manuscript copy of the Calendarium and Ephemerides as published by Regiomontanus in 1474 in Austria. The Calendarium, for 1475-1530, gives information on lunar and solar eclipses, the length of days, and the signs of the zodiac and planets. Also includes a table of time corrections for cities in reference to a longitude of approximately 10 degrees east (thus making no correction for Braunschweig, Nuremberg, Ulm, or Milan).

The Ephemerides, consisting only of tables updated to begin in 1480 and ending in 1506, provides positions for the sun, moon, and planets for each day of each year
