Translations of Kepler’s Astrological Writings Part III, Section 3. David Fabricius and Kepler on Fabricius’s Directions, 1603-1604

Abstract

We have seen Kepler’s theories about directions, including examples, in Part III.1. In Part III.2, Kepler also discussed the theory of directions (see pp. 281-283). Now we present a short correspondence between Kepler and David Fabricius on the topic of Fabricius’s directions, and Kepler’s interpretation of them.
