Together with a fragment from an ethical treatise by Joshua di
Viana, is an exchange of letters between Chasdai ibn Shaprut, the
head of the Jewish community in Cordova, Spain, and Joseph, the
King of the Khazars. The letter is the basis of the Kuzari, a
philosophical work by Yehuda Halevi written some two hundred years
after this correspondence. These letters were printed in many
editions of the Kuzari translated by Ibn Tibun into Hebrew and
differ somewhat from the text of this manuscript. The verse
preceding the letter and the letter from Chasdai is much the same
with small variations, but the reply from King Joseph has several
important variations. The Christ Church codex is the only known
manuscript of the first letter.
