From Scientific American:
A little blast from the past to puzzle over while your head spins from chocolate overload this weekend.
Two centuries before M.C. Escher confounded us with his optical illusions and play on perspective, William Hogarth (1697-1764) created Satire on False Perspective. Hogarth was a British painter and engraver sometimes credited with beginning the tradition of sequential art in Western culture due to his series of paintings depicting the rise and fall of a dandy, A Rake’s Progress. Complicated methods of using perspective to create an illusion of 3-dimensions in 2-dimensional art had been mastered (again) in Renaissance art a few centuries earlier. As well as a painter, Hogarth was something like a political cartoonist and satirist in his day. Here, in his engraving Satire on False Perspective are a number of errors. Can you spot them all?
