compelling account of this fascinating illusion. Taking us through the history, the characters involved, the attempts made to explain the illusion, though to modern day studies of visual perception, the book is the most comprehensive account of this puzzle so far. This is a work that will remain,
for some time to come, the definitive book on a mystery that has fascinated and tested the greatest minds throughout the ages.
Accessibly written, it will appeal to readers of popular science, along with those within the disciplines of psychology, mathematics, astronomy, and philosophy, from undergraduate upwards.
