Grafimathematical illusions

Optical illusions have been studied for millennia. The ancient Greeks used a technique known as entasis which incorporates a slight convexity in the columns of the Parthenon to compensate for the illusion of concavity created by parallel lines. Many of the following illusions have been popularized by psychologists and artists like Ehrenstein, Meyer, Zöllner, Müller-Lyer, Poggendorf, Escher and Baartman.
