Leonardo da Vinci's Vitruvian Man Paper Plate

Leonardo da Vinci's Vitruvian Man ...his study of human proportion to a circle and to a square. This is one of the most famous of drawings by Leonardo da Vinci. But, he drew this after an earlier similar drawing by one of his friends and both were using a concept by the much earlier Roman architect Vitruvius of the 1st century BC. Another illustration of a divinely proportioned man—the subject is Christ-like, but the setting is strikingly similar to Leonardo's—has been discovered in a forgotten manuscript in Ferrara, Italy, drawn by Giacomo Andrea de Ferrara, a Renaissance architect, expert on Vitruvius, and close friend of Leonardo's. Both drawings are depictions of a passage written 1,500 years earlier by Vitruvius, an ancient Roman architect, in which he describes a man's body fitting perfectly inside a circle (the divine symbol) and inside a square (the earthly symbol).
