Simultaneously a literary agitation against the Jews was set on foot by the clerical party. Father Moyetzki published in 1598 in Cracow his ferociously anti-Jewish book entitled "Jewish Bestiality" (_Okrucieństwo Żydowskie_), enumerating all ritual murder trials which had ever taken place in Europe and particularly in Poland, and adding others which were invented for this purpose by the author.[62] A Polish physician, named Shleshkovski, accused the Jewish physicians, his professional rivals, of systematically poisoning and delivering to death good Catholics, and declared the pest, raging at that time, to be a token of the Divine displeasure at the protection granted to the Jews in Poland (_Jasny dowód o doktorach żydowskich_, "A Clear Argument Concerning Jewish Physicians," 1623). But the palm undoubtedly belongs to Sebastian Michinski, of Cracow, the frenzied author of the "Mirror of the Polish Crown" (_Zwierciadlo korony Polskiej_, 1618). As a docile pupil of the Jesuits, Michinski collected everything that superstition and malice had ever invented against the Jews. He charged the Jews with every mortal sin--with political treachery, robbery, swindling, witchcraft, murder, sacrilege. In this scurrilous pamphlet he calls upon the deputies of the Polish Diet to deal with the Jews as they had been dealt with in Spain, France, England, and other countries--to expel them. In particular, the book is full of libels against the rich Jews of Cracow, with the result that the sentiment against the Jewish population of that city rapidly drifted towards a riot. To forestall the possibility of excesses the King ordered the confiscation of the book. The incendiary attacks of Michinski also led to stormy debates at the Diet of 1618. While some deputies eulogized him as a champion of truth, others denounced him as a demagogue and a menace to the public welfare. The Diet showed enough common sense to refuse to follow the lead of a writer crazed with Jew-hatred; yet the opinions voiced by him gradually took hold of the Polish people, and prepared the soil for sinister conflicts.
