720 SERENE (aka Serenus) (Babylon)
A recent convert was discovered to having seduced a local Jewish girl. Offended by the reaction, he decided to take revenge by pretending to be the messiah. He requested that people give him their wealth so that he could prepare a march to the holy land. He also urged that the Talmud be abolished. Caliph Yezid, Omar's successor, arrested this "Messiah" and handed him over to the Jews in Pumbedita for punishment. Natronai ben Nehemia (Gaon) urged the Jewish community to readmit their brethren into the fold. They eventually did so, though they were initially reluctant.
