"In 1922, Matthew Luckiesh wrote an optical illusions book titled - Visual Illusions: Their Causes, Characteristics and Applications. It was probably the first book to comprehensively cover the topic of Optical Illusions, or Visual Illusions, as they were called then.
On this optical illusion web site, we present this book to you, chock full of optical illusion information. It will be of interest to both the person who is fascinated by optical illusions and asks, "How do optical illusions work?" and also to the person doing serious research on the science of optical illusions. Some editing of the book has been done."
