Woodcut from the Divina Proportione, Luca Pacioli 1509, Venice, depicting the golden proportion as it applies to the human face.

"Medieval European interest in mathematics was driven by concerns quite different from those of modern mathematicians. One driving element was the belief that mathematics provided the key to understanding the created order of nature, frequently justified by Plato's Timaeus and the biblical passage (in the Book of Wisdom) that God had ordered all things in measure, and number, and weight."
