ABSTRACT
The recent publication by Jose Chabas and Bernard R. Goldstein of a detailed study of the astronomical works of Abraham Zacut represents the first serious attempt to evaluate these works and place them within the context of Iberian astronomy at the end of the Middle Ages. Some twenty years ago Goldstein himself presented an important collection of new materials on Zacut and thus laid the foundations for a new approach to this important figure after the pioneering study of F. A cursory reading of this text, compared to MS Milan Ambrosiana 338 and Rabat Hassaniyya 8184 and 1433, gives me the impression that the author of this recension has begun by correcting al-Hajan’s Arabic which - understandably in an author who spent the first thirty years of his life in the Spain of the beginning of the seventeenth century - was by no means faultless.
