This paper seeks to show that astronomical tables (zījes) belonging to the tradition of Ibn Isḥāq al-Tunisī (fl. 1193-1222) were available to the astronomers in the service of King Alfonso X (r. 1252-1284), who used them both in their astronomical works written in Castilian and for the production of the Parisian Alfonsine Tables which are, nowadays, extant in Latin.
