Did you know?

If you’ve ever spotted an image of a dog or a shoe in the clouds, you’ve exhibited what is called pareidolia, the tendency to perceive a meaningful image in a random pattern. Pareidolia emerged in English in 1962, borrowed from the German word Pareidolie, itself a combination of the Greek prefix par-, the Greek noun eídōlon (“image, reflection”), and the German suffix -ie. But although the word may be relatively new to English speakers, the concept is not. During the Renaissance, for example, artists such as Giuseppe Arcimboldo—who painted collections of fruits, vegetables, and other objects to look like human portraits—used pareidolia as a technique in their work, while Leonardo da Vinci once wrote, “… if you look at any walls spotted with various stains or with a mixture of different kinds of stones, if you are about to invent some scene you will be able to see in it a resemblance to various different landscapes adorned with mountains, rivers, rocks, trees, plains, wide valleys, and various groups of hills.” So the next time you see the man or even a toad in the moon, you can think of your kinship with Da Vinci.

pareidolia

noun

par·​ei·​do·​lia ˌper-ˌī-ˈdōl-ē-ə, -ˈdōl-yə 

: the tendency to perceive a specific, often meaningful, image in a random or ambiguous visual pattern

The human brain is optimized to recognize faces, which could also explain why we are so good at picking out meaningful shapes in random patterns. This phenomenon, pareidolia, could be responsible for a host of otherwise unexplained sightings, such as the face of the Virgin Mary on a toasted cheese sandwich.
