Mathematical Treasure: Kepler's Rudolphine Tables and defense of Brahe

Author(s): 
Frank J. Swetz (The Pennsylvania State University)

In 1627, Johannes Kepler (1571-1630) published his Rudolphine Tables (Tabulae Rudolphinae), a collection of astronomical tables based mainly on the previous work of Tycho Brahe (1546-1601). The book also included tables of logarithms calculated by Kepler. The Tables were named in honor of Kaiser Rudolf II, then Emperor of the Holy Roman Empire and Kepler’s patron.

In 1625, Kepler published Tychonis Brahie Dani Hyperaspistes, a defense of the work and findings of Tycho Brahe.
