The Messianic precursor of Ispahan found many partisans, 10,000 Jews, it is said, gathering around him for the purpose of aiding him in his work of deliverance. To them Abu-Isa expounded a form of Judaism differing in some respects from that accepted at the time; the points of difference, however, are not known. He entirely abolished divorce, even in the case of adultery. He augmented the three daily periods for prayer by four new periods, citing in support of this innovation the verse of a psalm: "Seven times a day do I praise thee." Abu-Isa retained the forms of prayer as prescribed by the Talmud, and in no way disturbed the existing order of the calendar. He explained his own peculiar system of religion in one of his works, in which he prohibits the use of meat and wine by his followers, but pronounces the abrogation of sacrificial worship. Abu-Isa desired to accomplish his Messianic task of liberation with sword in hand. He accordingly made soldiers of his followers, and rode at their head like a general. There could have been no more favorable moment for an attempt to regain liberty by open force. In all the provinces of the Mahometan empire the spirit of rebellion against Mervan II, the last Caliph of the Ommiyyad dynasty, was aroused. Ambitious governors, dissatisfied partisans, the Abassides, who laid claim to the supreme power, all these antagonistic elements conspired to overthrow the house of Ommiyyah, and turned the wide dominions of the empire into a battlefield of fierce passions. During this period of rebellion, Abu-Isa and his band seem to have begun their work of deliverance in the neighborhood of Ispahan. They probably strengthened their position during the disturbances consequent upon the severe defeat sustained by Mervan's general on the Euphrates (at Kerbella, August, 749). Finally, Abu-Isa fell in battle; his followers dispersed, and the Jews of Ispahan had to suffer for his revolt. His adherents, however, loyally cherished his memory; under the name of Isavites or Ispahanites they continued to exist until the tenth century, forming the first religious sect to which Judaism had given birth since the fall of the Jewish state. The Isavites lived in accordance with their master's teaching, observing some points of Talmudical Judaism, while disregarding many others. During this time, however, no extraordinary movement occurred in the center of Jewish religious life; everything continued on the old lines, the principals of the colleges and the Geonim succeeded each other without leaving any perceptible traces behind them. They had no suspicion that a new spirit was abroad in Judaism, which would shake it to its very foundations. CHAPTER V. RISE OF KARAISM AND ITS RESULTS.
