The Wonderful Art of the Eye : A Critical Edition of the Middle English Translation of His de Probatissimo Arte Oculorum

A thirteenth-century treatise on the theory and practice of ophthalmology, this unique work provides a window on what passed for medical knowledge of the eye during the late Middle Ages. Although little is known of the author, Benevenutus Grassus, he seems to have roamed Italy in the early thirteenth century as a medical practitioner specializing in diseases of the eye.
