The "Melekh Artus" (King Arthur) is a fascinating 13th-century Hebrew-language romance by an anonymous northern Italian Jewish author. Directly based upon the medieval Arthurian legends, the story presents Arthur as a figure fitting within a Jewish moral framework, with numerous references to Torah.
The work is primarily modeled on the Old French Arthurian prose romances, including the comprehensive Vulgate Cycles, with its storylines also concerning the wizard Merlin and Sir Lancelot of the Lake. Its author adapted and translated them into Hebrew, citing rabbinical authority for his endeavor. He particularly focuses on the tales concerning Arthur's birth (via his mother Ygraine's seduction) and the affair between Lancelot and Queen Guenevere, then also hinting at the Grail Quest.
The many stories of King Arthur and his Noble Knights, along with other romances of chivalry, have continued to be exceedingly popular with Jewish audiences, and several Yiddish editions of the Arthurian legends also exist from the 14th to 18th centuries.
