One of the earliest texts on the eye—its structure, its diseases, its treatments—Ten Treatises on Ophthalmology, was written in the ninth century by the Arab physician Hunayn ibn Ishaq. The individual components of the eye, he wrote, all have their own nature and they are arranged so that they are in cosmological harmony, reflecting, in turn, the mind of God.
