through his influence.

The "heresy" spread over many parts of the empire, and the number of its
adherents constantly grew. Archbishop Nikk complains that in the very
monastery of Moscow there were presumably converted Jews, "who had again
begun to practice their old Jewish religion and demoralize the young
monks." In Poland, too, proselytism was of frequent occurrence,
especially in the fifteenth and sixteenth centuries. The religious
tolerance of Casimir IV (1434-1502) and his immediate successors, and
the new doctrines preached by Huss and Luther, which permeated the upper
classes of society, rendered the Poles more liberal on the one hand, and
on the other the Jews more assertive. We hear of a certain nobleman,
George Morschtyn, who married a Jewess, Magdalen, and had his daughter
raised in the religion of her mother. In fact, at a time when Jews in
Spain assumed the mask of Christianity to escape persecution, Russian
and Polish Christians by birth could choose, with little fear of danger,
to lead the Jewish life. It was not till about the eighteenth century
that the Government began to resort to the usual methods of eradicating
heresy. Katharina Weigel, a lady famous for her beauty, who embraced
Judaism, was decapitated in Cracow at the instigation of Bishop Peter
Gamrat. On the deposition of his wife, Captain Vosnitzin of the Polish
navy was put to death by auto-da-fe (July 15, 1738). The eminent "Ger
Zedek," Count Valentine Pototzki, less fortunate than his comrade and
fellow-convert Zaremba, was burnt at the stake in Vilna (May 24, 1749),
and his teacher in the Jewish doctrines, Menahem Mann, was tortured and
executed a few months later, at the age of seventy. But these measures
proved of little avail. According to Martin Bielski, the noted
historian, Jews saved their proselytes from the impending doom by
transporting them to Turkey. Many of them sought refuge in Amsterdam.
For those who remained behind their new coreligionists provided through
collections made for that purpose in Russia and in Germany. To this day
these Russian and Polish proselytes adhere steadfastly to their faith,
and whether they migrate to America or Palestine to escape the
persecution of their countrymen, they seldom, if ever, indulge in the
latitudinarianism into which many of longer Jewish lineage fall so
readily when removed from old moorings.[17]

That the Russian Jews of the day were not altogether unenlightened, that
they not only
