6. al-Kindi, 850 CE

al-Kindi (d. 873) was an Islamic heir to Plato and the Neoplatonists. For him, the soul was an emanation from the One, as light from the Sun. (Lindberg, 1983; p. xliv) His astrological work, De radiis was an important influence on Grosseteste, Bacon, Ficino, and Dee. This work presented an astrological theory based on rays from the planets. Everything radiates. Space is full of these radiations.
