SIX VOLUMES OF THE RARE SABBIONETA EDITION OF THE RI". F. Isaac Alfasi brought the Geonic period to a close. His fame rests on this great work, whose purpose was to provide a comprehensive compendium for ready reference to facilitate Talmud study. The work remains an important and widely admired code, indeed Joseph Karo regarded Alfasi’s scholarship with utmost respect and determined the laws of his Shulchan Aruch upon his authority. Between the 16th and 19th centuries when the printing of the Talmud was banned in Italy, Alfasi’s work was expressly exempt and thus became a principal subject of study among Italian Jews.
