---- EDITION ORIGINALE ---- BEL EXEMPLAIRE ---- "PLATEAU was one of the best-known belgian scientist of the nineteenth century. His early work was on the field of physiological optics. The basis of much of this work was his observation that an image takes an appreciable time to form on, and to disappear from, the retina... He also studied various optical illusions that result from the persistence of the image on the retina... PLATEAU studied in great detail the phenomena of accidental colors and irradiation, both of which he considered as arising from a similar cause related to the persistence of the image on the retina...".
