Opticae Thesaurus: Alhazeni Arabis libri VII & Vitellonis libri X
Ibn al-Haytham (Alhazen); Witelo; ed. Federico Risner
Only partial translations or excerpts exist. This is the first complete English translation.
The 1572 'Opticae Thesaurus' is a compendium of two major works. While Alhazen's 'De Aspectibus' (Books I–VII) has been fully translated from this Latin edition by A. Mark Smith (2001–2010), Witelo's 'Perspectiva' (Books I–X) has only been partially translated (Books I–III and V). Consequently, no complete English translation of the entire 1572 volume exists.
Alhacen's Theory of Visual Perception (Books I–III); Alhacen on the Principles of Reflection (Books IV–V); Alhacen on Image-Formation (Book VI); Alhacen on Refraction (Book VII), trans. A. Mark Smith (2001-2010) [complete]

This volume is the definitive collection of medieval optics, bridging the work of the Arab master Alhazen with the expansive geometric legacy of Witelo. It systematically dismantles the ancient theory that eyes emit rays to touch the world, proving instead that light acts as a physical force upon the eye. The authors detail how the mind interprets light, color, and distance through complex cognitive processes. By analyzing everything from the anatomy of the eye to the physics of reflection in curved mirrors, the text provides a blueprint for understanding both the beauty and the deception of human sight. It remains a essential record of how humanity learned to trust mathematics over intuition.
