The only Hebrew version of the perennially popular Arthurian legends was written in northern Italy in 1279. […] The 13th-century Italian Jewish translator’s literary methods are as fascinating as are the Arthurian stories in Hebrew dress. The scribe not only translates from Italian, [..] he also changed and Judaized the story. The scribe’s manner of Judaization is evident at the outset of the romance; the apology itself is filled with terms from a familiar Jewish world.
Instrumental to the Judaization of the Arthurian romance are the scribe’s choice of plot (the seduction of Igerne by the king, with its parallels to the David-Bath-Sheba story), additions and omissions, use of language, and treatment of certain passages to stress Jewish ideas. For instance, the feast at which Uther meets Igerne is described in the Old French sources as a Christmas feast. In the Hebrew version, the statement “Then the king made a great feast for all the people and all the princes” (based on Esth. 2:18) conveys the aura of a Purim feast.
Another example of such transference of concepts occurs when the translator takes the talmudic word tamḥui (“a charity bowl from which food was distributed to the needy”), with its uniquely Jewish associations, to describe the grail, an overtly Christian symbol. The constant use of well-known biblical phrases reminds the reader of religious literature and produces the effect of biblical scenes in the midst of the Arthurian narrative. In this fashion, then, the text and the language interact in polyphonic fashion."
