The Supposed Miracle, or Cracovians and Highlanders with libretto of W. Bogusławski and music composed by Jan Stefani (1746-1829) embodies the Polish tradition, the riches and beauty of the musical culture of a nation which made that culture a crucial element in its survival.

Besides its artistic qualities, it is also a priceless phonographic document of one of the most important works in the Polish musical literature. An opera in two acts, Václav Luks, with his two internationally renowned ensembles Collegium 1704 and Collegium Vocale 1704 and young Polish and Czech singers, approached the original score newly edited and published by PWN Edition on the basis of source materials. This is the first studio recording on period instruments.
