Some Jews had got wind of the printing of Eisenmenger's work at Frankfort, and were not a little alarmed at the danger threatening them. The old prejudices of the masses and the ecclesiastics against Jews, stronger amongst Protestants than Catholics, still existed too strongly for a firebrand publication to appear in German without doing mischief wherever it came. The Jews of Frankfort therefore placed themselves in communication with the court-Jews at Vienna in order to meet the danger. Emperor Leopold I, who, at the instigation of the empress and her father-confessor, had expelled the Jews from Vienna, being in need of money in consequence of the Turkish wars, fifteen years later allowed some rich Jews to settle in the capital. Samuel Oppenheim, of Heidelberg, a banker, one of the noblest of Jews, whose heart and hand were open to all sufferers, had probably brought about this concession. As before, several Jewish families, alleged to be his servants, came with him to Vienna. Samuel Oppenheim zealously endeavored to prevent the circulation of Eisenmenger's book against the Jews. He had the same year experienced what a Christian rabble instigated by hatred of Jews could do. A riotous assault was made upon his house, which was broken into, and everything there, including the money-chest, was plundered (July 17, 1700). Hence from personal motives and on public grounds Samuel Oppenheim exerted himself to prevent the 2,000 copies of Eisenmenger's work from seeing the light of day. He and other Jews could justly maintain that the publication of this book in German, unattractive though its style was, would lead to the massacre of the Jews. An edict was therefore issued by the emperor forbidding its dissemination. Eisenmenger was doubly disappointed; he could not wreak his hatred on the Jews, and he had lost the whole of his property, which he had spent on the printing, and was obliged to incur debts. All the copies, except a few which he had abstracted, were in Frankfort under lock and key. He entered into negotiations with Jews, and proposed to destroy his work for 90,000 marks. As the Jews offered scarcely half that sum, the confiscation remained in force, and Eisenmenger, deceived in all his hopes, died of vexation.
