2. A Lutheran Astrologer: Johannes Kepler
3. In his translation of Kepler's Astronomia nova, Donahue suggests that the term ‘theorist’ best captures the sense of the astronomical ‘artifex’. In the above passage, the term ‘craftsman’ has been chosen on account of its ability to integrate the roles of the theorist and of the manufacturer in the single person of the Creator. See Kepler Johannes, New astronomy, transl. by Donahue William H. (Cambridge, 1992), 20–21.
