The Caterpillar is a character in Lewis Carroll's Alice's Adventures in Wonderland, a novel that is considered to be one of the best examples of the literary nonsense genre. This illustration is noted for its ambiguity; the Caterpillar's head can be viewed as being a human male's face with a pointed nose and pointy chin, or being the head end, with two legs, of an actual caterpillar.
