Euclid's Optics is a work on vision written around 300 BC. The earliest surviving manuscript of Optics is in Greek and dates from the 10th century AD. It focuses almost completely on the geometry of vision with little reference to either the physical or psychological aspects of sight. No Westerner had previously given such mathematical attention to the subject of vision. Euclid's work influenced many later Greek, Islamic, and Western European Renaissance scientists and artists. Heliodorus of Larissa (fl. 3rd century?) first propounded the axiom that light on being reflected always chooses the shortest way.
