The medieval Latin version of Ibn al-Haytham’s Kitab al-Manazir, Alhacen’s De aspectibus provides a comprehensive treatment of vision from the physics of light to the psychology of misperception. Consisting of seven books, it is divided into three sections by topical focus, the first section consisting of books 1–3, which deal with visual perception in general. The primary intent of the analysis in this section is to show how the visual system works and how the working of that system is affected by ambient circumstances, such as too much light or too great a distance between eye and object.
