Israel Sarug

Israel Sarug Ashkenazi (Hebrew: ר׳ ישראל סרוג אשכנזי, also סרוק Saruk or Srugo, known also as רי״ס the Ris and מהר״י סרוג Mahari Sarug, was a pupil of Isaac Luria who devoted himself at the death of his master to the propagation of Lurianic Kabbalah, through which he gained many adherents in various parts of Italy. Among these, the most prominent were Menahem Azariah da Fano, whom he persuaded to spend large sums of money in the acquisition of Luria's manuscripts; and Aaron Berechiah of Modena, author of the Ma'avar Yabbok. Sarug also lectured in various places in Germany and in Amsterdam. In the latter city one of his disciples was Abraham Cohen de Herrera.
