Obrazowanie postaci św. Jana z Kęt w łacińskim i polskim kaznodziejstwie doby baroku

St. John Cantius – a student and professor of the Krakow Academy – holds a significant place in Old Polish writings. Literary forms preserving the cult of Master John included Latin and Polish sermons, which were initially written to celebrate the anniversaries of the saint’s death, and then his liturgical memorial day. The method of the representation of St. John Cantius in selected Baroque sermons is the subject of the analysis carried out in this article. The use of light-related metaphors by their authors, for instance, by referring to John Cantius as a sun, star, lamp, torch, or fire, is the common element of the analyzed texts. Undoubtedly, the application of such metaphors has its source in the Christian philosophical and theological thought. Moreover, it is a manifestation of paravisual tendencies and fascination with the sun, typical of the literature of the Baroque period.
