Sample text

Aguilonius wrote a textbook on optics: Opticorum libri VI (1613). This book is famous for two reasons: its detailed treatment of geometrical optics and the beautiful illustrations, made by Aguilonius' friend, Peter Paul Rubens. A large part of the book is taken up by the theory of stereographic projection, a subject which was very important at the time in connection with cartography. But the detailed treatment of color also places Aguilonius apart from his perspectivistic predecessors. Aguilonius distinguishes three sorts of colors.

In his treatises on light and color Bacon tries to combine Aristotle (color and light as form without material) and Alhazen (color and light as radiation from all points). He considers (in the manner of the neoplatonist AI-Kindi) that all things radiate powers in media which are receptive to them. Thus the magnet sends outpowers, species, which act on receptive iron. This also applies to the sun, which surrounds itself with a field of power, in this case light-species. This is not a material emanation, otherwise the sun would have burnt out long ago!

This view was correct, but it was not accepted before the time of Boyle and Newton. It is worth pausing here to consider the fact that optics at the time of Kamal al-Din had reached the same level in the East as in the West. Why did Western knowledge develop further at ever increasing speed? Was that the result ofthe institutionalization of western learning in the universities? Or was it the early link between science and technology? Perhaps it was merely a question of chance: the islamic civilization was unlucky enough to be overrun by barbarian hordes; in 1258 Bagdad fell into the hands ofHulagu Khan.
