ABSTRACT
Research into Christian demonology is an area of scholarship with a long history and old traditions, and has resulted in a vast and extensive body of work, testifying to the involvement of the most varied disciplines. Comprehensive study of the printed and manuscript sources of early modern Catholic demonology in Central Europe and, within that, in Hungary is a long-term task which awaits the efforts of a whole line of well-trained scholars. Besides the normative documents of religious demonology, another invaluable set of sources for research are the archive documents which represent local practice or, in the most fortunate cases, the demonological views of a particular clerical personality. The letters written by our protagonist also reveal what were the parts of the above-mentioned demonological literature that he actually came in contact with throughout his life and activity.
