O pryncypiach literackich Jana Stanisława Jabłonowskiego. Notata niektóre o poezji polskiej

The primary goal of this article was to present an excerpt from a manuscript by Jan Stanisław Jabłonowski, found in the collection “To, co szlachcic polski wiedzieć powinien” (Archive of Jabłonowski of Bursztyn, reference DE-18845). The work, despite its conventionality (the text is modelled on Jesuit poetics and compendia of knowledge), reveals a number of this author's observations, hitherto elusive and not conveyed in any of this author's auto-thematic statements. Jabłonowski's “Poetics” is accompanied by an introduction reconstructing the history of the manuscript's creation. The text has been transcribed, the rules of publication have been indicated, and explanatory comments have been offered.
