THÉORIES ET VOCABULAIRE DE LA VISION DANS LES MONDES GREC ET LATIN DU IV e AU XII e SIÈCLE

Abstract : During the late Antiquity, the theories of Plato and Aristotle about the solar or ocular light's movements are the basis of the theory of vision. The neoplatonic approach of the greek commentators to Aristotle, influenced by geometry and physiology, has been passed on to the Latin Occident, which was actually closer to Platon's Timaeus – available in traduction, unlike Aristotle's work. In order to explain the formation of the image in the observer's soul, the Greeks combine elements of Aristotle and Galen. The Occident focuses on the subject's interiority: the Augustinian theory enlarge the visual theory to create a thought's one. Then it's redefined during the twelth century under the influence of Boece's classification of the soul's forces. The propagation of light is a crucial element of vision. From the God-light's metapher, the Greek fathers developp a metaphysical speech influenced by Aristotle's physic. John Scotus Eriugena passes it on to the Latin world, where it comforts the Augustinian theory of vision. During the twelth century, this metaphysics changes to physics (optics) by means of the Timaeus' studies. Whereas in greek there is a continuity with the antique vocabulary, a specialised lexicon tends to appear in latin, through the greek and an autonomous thought, respectively. This lexicon, testimonial of the powerfull reflexion on optic during the early Middle Ages, is used in the twelth century's translations, which renew the knowing of this discipline in Occident.
