Lunar pareidolia

Lunar pareidolia is the perception of images on the face of the Moon. The Moon's surface is a complex mixture of dark areas (the lunar maria, or "seas") and lighter areas (the highlands); perceiving patterns in disordered visual stimuli is known as pareidolia. Being a natural element seen constantly by humans throughout the ages, many cultures have seen shapes in these dark and light areas that have reminded them of people, animals, or objects, often related to their folklore and cultural symbols; the best-known are the Man in the Moon in Western folklore and the Moon Rabbit of Asia and the Americas. Other cultures perceive the silhouette of a woman, a crow, a frog, a moose, a buffalo, or a dragon (with its head and mouth to the right and body and wings to the left) in the full moon. To many cultures of Melanesia and Polynesia, the Moon is seen to be a cook over a three-stone fire. Alternatively, the vague shape of the overall dark and light regions of the Moon may resemble a Yin Yang symbol.
