Moreover, even the Hebrew scholar is obliged to exercise some discrimination if he desires to consult the Talmud in its original form. For by the sixteenth century, when the study of Hebrew became general amongst Christians, the antisocial and anti-Christian tendencies of the Talmud attracted the attention of the Censor, and in the Bâle Talmud of 1581 the most obnoxious passages and the entire treatise Abodah Zara were suppressed.[79] In the Cracow edition of 1604 that followed, these passages were restored by the Jews, a proceeding which aroused so much indignation amongst Christian students of Hebrew that the Jews became alarmed. Accordingly a Jewish synod, assembled in Poland in 1631, ordered the offending passages to be expunged again, but--according to Drach--to be replaced by circles which the Rabbis were to fill in orally when giving instruction to young Jews.[80] After that date the Talmud was for a time carefully bowdlerized, so that in order to discover its original form it is advisable to go back to the Venetian Talmud of 1520 before any omissions were made, or to consult a modern edition. For now that the Jews no longer fear the Christians, these passages are all said to have been replaced and no attempt is made, as in the Middle Ages, to prove that they do not refer to the Founder of Christianity.[81] Thus the _Jewish Encyclopædia_ admits that Jewish legends concerning Jesus are found in the Talmud and Midrash and in "the life of Jesus (Toledot Yeshu) that originated in the Middle Ages. It is the tendency of all these sources to belittle the person of Jesus by ascribing to Him illegitimate birth, magic, and a shameful death."[82]
