Kepler's Logarithms

 

This is the title page of Johannes Kepler’s (1571—1630) Chilias Logarithmoria, 1624, logarithmic tables he constructed by geometric procedures. Kepler also gave a proof of why logarithms worked and then used them extensively in his calculations of the Rudolphine astronomical tables.
