Ibn 'Azzuz al-Qusantini's tables for computing planetary aspects

This paper presents a chapter of the fourteenth century al-Zīj al-Muwāfiq by Ibn al-Azzūz al-Qusantīnī (d 1354) containing the only known example of numerical tables designed for the computation of the astrological aspects following the most popular method for this practice in the Islamic area: that...
