Introduction

  Among the three oldest Polish astronomical observatories belonging to the universities in Vilna, Cracow and Warsaw, the Cracow University Observatory was fortunately able to act continuously since the year of its foundation (1791-1792) until present.

Also in Cracow the longest in Poland, unbroken series of meteorological observations has been recorded and preserved. However, the beginning of the institution was rather difficult. The idea of setting up the astronomical observatory in Cracow did not find there, in the first half of 18th century, a favorable atmosphere. The excellent astronomical traditions of the Cracow Academy, dating back to the 15th century (cf. H. Schedel, Liber Chronicarum, Nürnberg, 1493), were then forgotten. Moreover, the further progress in astronomy was not followed there. At the Cracow University the heliocentric theory of Copernicus, its most prominent student, was not accepted and the syllabus including the lectures on astronomy according to Ptolemy and Peuerbach was obligatory till 1750 AD and later on.
