ABSTRACT
What the authors know about Andalusian influence on Maghribl astronomy begins in the 13th century when Abu l-‘Abbas Ibn Ishaq al-Tamimi al-Tunisi, prepared a set of tables which survive in a unique manuscript in Hyderabad, discovered in 1978 by D.A. King. This manuscript was copied in Hims (Syria) in 1317 A.D. An edition of the whole set of canons and an analysis of the numerical tables is being prepared in Barcelona by Angel Mestres. Ibn Ishaq’s work occupies a central position in the successive development of Maghribi zijes: it seems clear that he compiled a set of tables for the computation of planetary longitudes, eclipses, equation of time, parallax and, probably, solar and lunar velocity.
