The illustration is reproduced from: Tycho Brahe (1598) Astronomia
Instauratae Mechanica, now in the Royal Library, Copenhagen.
Tycho spent most of the time 1569-70 in Augsburg as the astronomical
collaborator of the city mayor. One of the outcomes was that he
had a wooden globe of five
feet diameter constructed. Ten years later when he had assured
himself that the globe kept a spherical form it was provided with
poles and divided circles for reading and for transforming between
celestial coordinates. After a further 15 years of work he had marked
the accurate positions of 1000 fixed stars on the surface. Tycho's
celestial globe stood as an impressive monument to his life's work.
The globe went with Tycho to Bohemia, was brought back as
booty of war in 1632 and was placed at the Observatory
(the Round Tower) in Copenhagen
where it was destroyed in the great fire of October 1728.
