A noxious plot was brewing against the Jewish community of Saragossa, but they were completely unaware of the looming danger. They were spared, however, thanks to a handful of synagogues beadles who acted on a dream they all had. The resulting salvation on the 17th of Shevat was celebrated by Saragossan Jews, and dubbed "Purim Saragossa."

A Hebrew Megillah (scroll) was penned, describing the details of the miraculous story. To this day, this scroll is read in certain communities on Purim Saragossa.
