Les très riches heures du Duc de Berry

This remarkable image on folio 14v depicts a subtly graduated painting of Anatomical Man, the front and partial, mirrored back view of a nude youth standing with the seven planets in a mandorla, which in turn is framed by an almond-shaped border containing the signs of the zodiac.

The zodiac surrounding Anatomical Man is a notable mediaeval pictorial invention, and was fully developed in the 13th century. It represents the belief that man is a microcosm, and therefore the reflection of the macrocosm, of the order in the universe as a whole.
