Rudolphine Tables logarithms. Table of logarithmic calculations for the 'Rudolphine Tables' (Tabulae Rudolphinae, 1627) by German astronomer Johannes Kepler (1571-1630). Using observations by Danish astronomer Tycho Brahe (1546-1601), these astronomical tables were the most accurate of the time. Kepler took 26 years to finish the task, the completion of which was entrusted to him by Tycho on his deathbed. The tables were completed in 1624 and published three years later. Their accuracy was due to the use of Tycho's observations and Kepler's use of logarithms in his calculations. They were named for Holy Roman Emperor Rudolf II.
