Dating
Some scholars think that the Magister Abraham who dictated De Astrolabio (probably at Toulouse) to Rudolf de Bruges (a work that the latter finished in 1143) was identical with Abraham bar Ḥiyya. As the title "Sephardi" (Spaniard) is always appended to his name, it is certain that he was Spanish. Nevertheless, he must have passed several years in southern France, likely Narbonne, as he composed some works for the Jews of Provence, in which he complains of their Provençal Jewry's ignorance of mathematics.
