Tychonis Brahe Astronomiae instauratae progymnasmata: quorum haec prima pars de restitutione motuum solis et lunae stellarumque inerrantium tractat, et praeterea´ de admiranda^ nova stella anno 1572 exorta^ luculenter agit, 1602. The 1st volume of a projected work on recent astronomical phenomena. The 2nd volume had been printed and privately distributed at Uraniborg in 1588 under title: De mundi aetherei recentioribus phaenomenis liber secundus. The 3rd and final volume was never written. Running title: De noua stella anni 1572. Prepared for publication after the author's death by Johannes Kepler. Tycho Brahe (December 14, 1546 - October 24, 1601) was a Danish astronomer and alchemist. As an astronomer he worked to combine the geometrical benefits of the Copernican system with the philosophical benefits of the Ptolemaic system into his own model of the universe, the Tychonic system. He was the last of the major naked eye astronomers and is credited with the most accurate astronomical observations of his time, and the data was used by his assistant, Johannes Kepler, to derive the laws of planetary motion.
