A Visual Illusion

Abstract

THE phenomenon referred to by Mr. Turner and by Prof. Boycott in NATURE of October 7 and 14, pp. 180 and 213, was described by Aristotle in his treatise on dreams (“Parva Naturalia”) thus: “Also, the senses are affected in this way when we turn quickly from; objects in motion, e.g. from looking at a river, and especially from looking at swiftly flowing streams. For objects at rest then seem to be in motion.”
