Tycho Brahe, Cartography and Landscape in 16th Century Scandinavia

A little more than 400 years ago, on 24 October, 1601, the great Danish astronomer, Tycho Brahe (Tyge Ottesen Brahe) died in Prague, where he is buried in the Teyn church. Tycho’s last assistant, and his successor as Imperial Mathematician to Emperor Rudolph II, was the German astronomer Johannes Kepler, who wrote at the end of Tycho Brahe’s log of astronomical observations (Dreyer 1926: 283, translated by Rosen 1986: 313, cited in Thoren 1990: 469):

At this time ... his series of celestial observations was interrupted, and the observations of 38 years came to an end.
