This drawing, of a man contained within a circle and a square, is one of the most recognizable in the world. It seems to fascinate people and has a way of transcending time and space to connect with its viewers. It also is really easy to parody.
The original document, pictured above and created by Leonardo Da Vinci, has two major components: the drawing itself, and two paragraphs of writing. Both deserve some attention, because while this image is rather commonplace in our culture, most people don’t realize how many layers there are.
First off, why is the drawing even called the “Vitruvian Man”? Is Vitruvius a place or something?
That was my first thought, but it turns out that Vitruvius was a man. Vesuvius = volcano, Vitruvius = man.
Vitruvius was a roman architect whose ten-part treatise on architecture, De architecura, was the only document about architecture to survive from antiquity. This means we owe much of our knowledge of the theory behind Roman aqueducts, central heating, and water pumps to this book. It is also the source of the (possibly apocryphal) story of archimedes, his discovery in a bathtub, and his shout of “Eureka!”.
Vitruvius held that the 3 basic elements of good architectural design were strength, functionality, and beauty. These elements are so important that they remain mainstays of modern architectural theory. He was also especially interested in proportion. He believed that ‘beautiful’ proportions were those based on nature. And what more perfect example of nature was there than Man?
He believed that a perfect male body would fit the following conditions and that these proportions could be used to design perfect buildings.
For if a man be placed flat on his back, with his hands and feet extended, and a pair of compasses centred at his navel, the fingers and toes of his two hands and feet will touch the circumference of a circle described therefrom.
And just as the human body yields a circular outline, so too a square figure may be found from it. For if we measure the distance from the soles of the feet to the top of the head, and then apply that measure to the outstretched arms, the breadth will be found to be the same as the height, as in the case of plane surfaces which are perfectly square.
And then his writings were lost for more than a thousand years.
They were re-discovered in the 1400s in Italy and gained traction amongst Renaissance artists.
And which Renaissance artist should be more intrigued by the challenge of drawing Vitruvius’ man than Leonardo Da Vinci, the namesake of everyone’s second favourite Ninja Turtle?
Da Vinci realized that in order for Vitruvius’ description to work, the centre of the square needed to be lower than the navel. This lateral thinking separated Leonardo from other artists whose attempts to keep the same centre for both shapes made their men look strange.
The other thing that separates Da Vinci’s Vitruvian Man is the dual positioning. It gives a sense of movement to the piece as if it is an early kind of animation. One unfortunate consequence of this is that the drawing doesn’t render very well in 3D and looks kind of like an alien:
The drawing itself certainly draws a lot of attention, but few take the time to look at the writing. This is partially because it is in illegible script, and the script is triply illegible to me. First of all, I’m just bad at reading old, faded cursive script. Second, it’s in Italian and I don’t understand Italian. Third, and most interestingly in my opinion, it’s written in mirror writing. Why he did this is unknown, but it might have helped him avoid smudging as he wrote with his left hand.
The content of the paragraphs describe all of the proportions present in the drawing. For Da Vinci (and Vitruvius), the distance between the tip of the fingers and the elbow is called one cubit and it is exactly six times the width of a palm and one quarter the height of a person.
There are 15 such proportions below that I encourage you to try out. How do you measure up to the Vitruvian Man?
- the length of the outspread arms is equal to the height of a man
- from the hairline to the bottom of the chin is one-tenth of the height of a man
- from below the chin to the top of the head is one-eighth of the height of a man
- from above the chest to the top of the head is one-sixth of the height of a man
- from above the chest to the hairline is one-seventh of the height of a man.
- the maximum width of the shoulders is a quarter of the height of a man.
- from the breasts to the top of the head is a quarter of the height of a man.
- the distance from the elbow to the tip of the hand is a quarter of the height of a man.
- the distance from the elbow to the armpit is one-eighth of the height of a man.
- the length of the hand is one-tenth of the height of a man.
- the root of the penis is at half the height of a man.
- the foot is one-seventh of the height of a man.
- from below the foot to below the knee is a quarter of the height of a man.
- from below the knee to the root of the penis is a quarter of the height of a man.
- the distances from below the chin to the nose and the eyebrows and the hairline are equal to the ears and to one-third of the face.
