Book of the Ten Treatises of the Eye

Book of the Ten Treatises of the Eye (Arabic: كتاب العشر مقالات في للعين, Kitab al-Ashr Maqalat fil-Ayn) is a 9th-century theory of vision written by Hunayn ibn Ishaq, based upon the cosmological natures of pathways from the brain to the object being perceived. This ophthalmic composition is heavily derived from Galen's De placitis Hippocratis at Platonis and De usu partium, both in terms of the anatomy and physiology being described.
