Cornelio Jansenio - Notarum Spongia quibus alexipharmacum civibus sylvae-ducensibus - 1666

This fierce theological text was written by Jansenius as a direct counter-attack against Gisbertus Voetius (a leading orthodox Calvinist minister in 's-Hertogenbosch, referred to as Sylva-ducensis). It forms part of the intense historical cross-confessional polemics between Catholic theologians and Reformed leaders in the Low Countries during the 17th century.
