Mark Smith continues his work on Alhacen's De Aspectibus with this volume. Alhacen’s study of image-distortion in Book 6 takes on a dual significance as an end to his reflection-analysis, not simply because it concludes that analysis but because it represents the ultimate goal for it. Accordingly, Alhacen’s purpose is to apply the cathetus-rule to an analysis of the various misperceptions that arise in the seven types of mirrors chosen for study in the previous books. Some of these misperceptions are common to all mirrors, an example being image-displacement.
Earlier volumes by Mark Smith on Alhacen include Alhacen's Theory of Visual Perception: A Critical Edition, with English Translation and Commentary, of the First Three Books of Alhacen's De Aspecitubus (Transactions 91-4 and 91-5, 2001) and Alhacen on the Principles of Reflection; A Critical Edition, with English Translation and Commentary, of Books 4 and 5 of Alhacen’s De Aspectibus (Transactions 96-2 and 96-3, 2006).
