Klappsonnenuhr, Georg von Peuerbach, 1455

Georg Peuerbach

Court astronomer and astrologer



The exhibition will be shown 2012!


Georg Peuerbach constructed the first folding sundial with inbuilt compass in 1451. This also took magnetic declination– the difference between geographical north and magnetic north - into account, which meant time could be stated precisely. As an astrologer, Peuerbach produced a horoscope for Eleonor of Portugal, the future bride of the Emperor Frederick III.
