Table from the 'Rudolphine Tables' (1627) (Tabulae Rudolphinae, 1627) by German mathematician and astronomer Johannes Kepler (1571-1630). Using observations by Danish astronomer Tycho Brahe, 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. Named for Holy Roman Emperor Rudolf II, the tables were used to calculate the past and future positions of planets and the Sun and Moon, as well as the timings of events such as solar and lunar eclipses.
