Rishonim
Rishonim (Hebrew: [ʁiʃoˈnim]; Hebrew: ראשונים, lit. 'the first ones'; sing. ראשון, Rishon) were the leading rabbis and poskim who lived approximately during the 11th to 15th centuries, in the era before the writing of the Shulchan Aruch (שׁוּלחָן עָרוּך, "Set Table", a common printed code of Jewish law, 1563 CE) and following the Geonim (589–1038 CE).
