was composed in al-Andalus by the Mâlikî jurist al-Imâm al-Qur
ubî in the heart of the 13
th century. It is the most relevant work to explore the nature of interreligious polemics
between Christians and Muslims in the Iberian Peninsula, but also to spur research into
Islamo-Christian polemics in al-Andalus.
The book was partially edited by Devillard in the seventies using one of the two Turkish
manuscripts that have survived, but some years later
al-Saqqâ published the complete edition.
However, a third manuscript composed in Jarbah and actually preserved in the Royal
Library in Rabat (Morocco) still remains unpublished.
The Moroccan text is the base of the present diplomatic edition of the ten fragments
pertaining to Christian texts contained in the codex. As the reader will see, textual
differences are at times of great interest, in that they highlight the manipulation to
which the manuscript was subjected during the editing process, and the substantial
alterations to which it gave rise
