The article focuses on the religious publications that were issued in Lvov in 1773-1800 by the printing press of the Lvov province, which belonged to Antoni Piller and later to his successors. Since the Pillers’ printing press was the only one active in the town between the latter half of the 1780s and the end of the 1790s, it accepted, apart from governmental printing orders, other commissions, including church and monastic ones. About thirty five religious texts were released by them. They were mostly prayer books and sermons, but also textbooks and religious education books, teaching guides for catechists, excerpts facilitating the understanding of the Gospel, as well as summaries of important Western European works that had an impact upon understanding the Christian religion and the debate of the existence of God.
