No other book composed in the early modern period had as profound and lasting an impact on Jewish life as Karo’s. The Shulhan ‘arukh (“The Prepared Table” or “The Ordered Table”) eventually became the standard code of Jewish law throughout Europe and the Mediterranean world. with few exceptions, nearly every Jewish community had accepted it as authoritative within generations of its initial publication. The Shulhan ‘arukh as a “writing” delivered to the Jewish public by Joseph Karo had a truly transformative impact upon Jewish life. In this way, one can speak of Karo’s work as a discourse, as an idea. The book served scholars as a reference work and literate lay people as a manual of Jewish law. It stimulated commentary and controversy, resistance and cooptation. One is hard pressed to find another book written in the early modern period that endured as long as the Shulhan ‘arukh.
