In 1740, just as clouds were gathering menacingly over them, Jesuits set to celebrate the two-hundredth anniversary of the foundation of the Society of Jesus. Among them, Jan Poszakowski (1684-1757), a Lithuanian Jesuit connected with the powerful Radziwiłł family, published a Jesuit calendar (Kalendarz jezuicki większy) including brief biographies of about two thousand his confreres from all over the world. Despite its compilatory character, the Kalendarz jezuicki is a reliable testimony of what readers from Poland-Lithuania could have known about the global activity of the Society of Jesus in the mid-eighteenth century. The proposed talk aims to explore what Poszakowski drew from other texts (i.e. Jan Drew's Fasti Societatis Jesu, Matthias Tanner's Societas Jesu usque ad sanguinis et vitae profusionem militans, and the Menologium Societatis Jesu) and how he adapted this material to the needs of his readers while translating it from Latin into Polish. In particular, the intertextual and rhetorical dimension of Poszakowski's book deserves investigation through statistical analysis based on RStudio, an integrated development environment (IDE) based on the programming language R.
