The Overture to the especially folkloristic three-act opera ''Superstition, or Cracovians and Mountaineers'' (subtitled, moreover, ''dramatic amusement with singing in three acts''), was written to a libretto by Jan Nepomucen Kaminski. The world premiere of the opera took place at the National Theatre in Warsaw on 16 April 1816. In the 19th century the opera was also called ''New Cracovians'', because Kurpinski's ''Superstition'' is an adaptation of an earlier, four-act opera ''The Supposed Miracle, or Cracovians and Mountaineers'' by Jan Stefani to words by Wojciech Boguslawski (staged 22 years before in 1794 at the National Theatre in Warsaw). The author of the libretto to Kurpinski's opera ''Superstition'' retained the thematic basis of Boguslawski's libretto, at the same time shortening the play to three acts. Owing to its enormous popularity, Kurpinski's opera soon caused its prototype to recede into the background. ''Superstition'' contributed greatly to the process of folklorization of Polish operatic music during the 1st half of the 19th century, becoming at the same time the most nationalist work by Kurpinski.
