Johannes Kepler (1571-1630) a German mathematician, astronomer & astrologer, author of one of greatest books on astronomy, the 'Astronomia nova' of 1609. Containing the results of his ten-year long investigation of the motion of Mars, it included the first mention of the elliptical path of the planets, suggesting that they were free floating bodies. These are now known as 'Kepler's laws of planetary motion'. In the field of Optics he designed the Keplerian Telescope, an improved version of Galileo's refracting telescope, 1611. The portrait was published in 'Allgemeine Geographische Ephemeriden' (Universal Geographical Ephemerides (i.e. encyclopedia)) by Friedrich Bertuch et al.
