In this paper, we analyze the astronomical tables in al-Zīj al-Muqtabis by Ibn al-Kammād (early twelfth century, Córdoba), based on the Latin and Hebrew versions of the lost Arabic original, each of which is extant in a unique manuscript. We present excerpts of many tables and pay careful attention to their structure and underlying parameters. The main focus, however, is on the impact al-Muqtabis had on the astronomy that developed in the Iberian Peninsula and the Maghrib and, more generally, on the transmission and diffusion of Indian astronomy in the West after the arrival of al-Khwārizmī's astronomical tables in al-Andalus (Muslim Spain) in the tenth century. This tradition of Indian origin competed with the Greek tradition represented by al-Battānī's astronomical tables and was much more alive in the Iberian Peninsula and the Maghrib than previously thought. From Spain, the Indian tradition entered mainstream European astronomy, where we find echoes of it in all versions of the Alfonsine Tables, both in manuscript and in the printed editions (beginning in 1483), as well as in Copernicus's De Revolutionibus, published in 1543.More than 20 years ago, we published in this journal a long paper on a set of astronomical tables in al-Zīj al-Muqtabis compiled by Ibn al-Kammād, an astronomer active in Córdoba at the very beginning of the twelfth century (Chabás and Goldstein 1994). In that paper, we focused on the tables in this zij and, by means of analyzing their structure and determining the underlying parameters, we identified some of Ibn alCommunicated by:
