Neznámé listy Josefa Steplinga Maximilianu Hellovi

This contribution includes the text and commentary on three letters, which Joseph Stepling wrote to Maximilian Hell. Two of these letters were written in 1757, one in 1759, and all were discovered in the archive of the Viennese astronomical observatory. They fall into a period covered by Stepling’s correspondence reprinted in the Litterarum commercium (Vratislaviae 1782), which makes it an interesting contribution to this subject.
