First collected edition of the Progymnasmata (first published posthumously by Kepler at Prague in 1602) and De mundi Aetherei (Uraniborg, 1588), the first two parts of a projected but never completed trilogy. The first work contains Brahe's observations of the supernova in Cassiopeia of 1572-1574, as well as his revisions of the theories of solar and lunar movement and a catalogue of the positions of 777 fixed stars. The second work records Brahe's observations of the comet of 1577, and a description of his geoheliocentric theory of the universe, a view that evolved from his study of these two astronomical phenomena, and which was one of several new theories that helped pave the way for acceptance of the Copernican doctrine.
