Pareidolia in practise

Pareidolia: the tendency to perceive a specific, often meaningful image in a random or ambiguous visual pattern. (Merriam-Webster dictionary)

Detail from The Virgin Adoring the Child by Sandro Botticelli

Here’s an example of Sandro Botticelli putting into practice some advice Leonardo da Vinci gave in one of his notebooks on the subject of Pareidolia. It’s a sample of several references Botticelli makes to Leonardo in his painting. More details at this link.

This is what Leonardo wrote in his notebook on the subject:

A Way of Development and Arousing the Mind to Various Inventions:
“I cannot forbear to mention among these precepts a new device for study which, although it may seem but trivial and almost ludicrous, is nevertheless extremely useful in arousing the mind to various inventions. And this is, when you look at a wall spotted with stains, or with a mixture of stones, if you have to devise some scene, you may discover a resemblance to various landscapes, beautified with mountains, rivers, rocks, trees, plains, wide valleys and hills in varied arrangement; or again you may see battles and figures in action; or strange faces and costumes, and an endless variety of objects, which you could reduce to complete and well drawn forms. And these appear on such walls confusedly, like the sound of bells in whose jangle you may find any name or word you choose to imagine.”
