Abstract

This contribution aims to introduce Michael’s doctrine of the soul, developed in the 4th distinctio of the Liber quatuor distinctionum, and to show how the soul is the fulcrum of Michael’s scientific reflection on astrology. Furthermore, some close similarities between Michael’s Liber introductorius and one of the best-known encyclopaedic works of the Andalusian world, the Epistles of the Ikhwān al-Ṣafāʾ, shed light on the richness of the Toledan milieu of the time and Michael Scot’s formative period in Toledo.
