Vitruvian Man

Subject and title

This image demonstrates the blend of mathematics and art during the Renaissance and demonstrates Leonardo's deep understanding of proportion. In addition, this picture represents a cornerstone of Leonardo's attempts to relate man to nature. Encyclopædia Britannica online states, "Leonardo envisaged the great picture chart of the human body he had produced through his anatomical drawings and Vitruvian Man as a cosmografia del minor mondo (cosmography of the microcosm). He believed the workings of the human body to be an analogy for the workings of the universe."

According to Leonardo's preview in the accompanying text, written in mirror writing, it was made as a study of the proportions of the (male) human body as described in Vitruvius' De architectura 3.1.2–3, which reads:

For the human body is so designed by nature that the face, from the chin to the top of the forehead and the lowest roots of the hair, is a tenth part of the whole height; the open hand from the wrist to the tip of the middle finger is just the same; the head from the chin to the crown is an eighth, and with the neck and shoulder from the top of the breast to the lowest roots of the hair is a sixth; from the middle of the breast to the summit of the crown is a fourth. If we take the height of the face itself, the distance from the bottom of the chin to the under side of the nostrils is one third of it; the nose from the under side of the nostrils to a line between the eyebrows is the same; from there to the lowest roots of the hair is also a third, comprising the forehead. The length of the foot is one sixth of the height of the body; of the forearm, one fourth; and the breadth of the breast is also one fourth. The other members, too, have their own symmetrical proportions, and it was by employing them that the famous painters and sculptors of antiquity attained to great and endless renown. Similarly, in the members of a temple there ought to be the greatest harmony in the symmetrical relations of the different parts to the general magnitude of the whole. Then again, in the human body the central point is naturally the navel. 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.

Yet, while Leonardo shows direct knowledge of Vitruvius, his drawing does not follow the description of the ancient text. In drawing the circle and square he observes that the square cannot have the same centre as the circle, but is centered at the groin. This adjustment is the innovative part of Leonardo's drawing and what distinguishes it from earlier illustrations. He also departs from Vitruvius by drawing the arms raised to a position in which the fingertips are level with the top of the head, rather than Vitruvius's much lower angle, in which the arms form lines passing through the navel.

It may be noticed by examining the drawing that the combination of arm and leg positions creates sixteen different poses. The pose with the arms straight out and the feet together is seen to be inscribed in the superimposed square. On the other hand, the spread-eagle pose is seen to be inscribed in the superimposed circle.

Leonardo's collaboration with Luca Pacioli, the author of Divina proportione (Divine Proportion) have led some to speculate that he incorporated the golden ratio in Vitruvian Man, but this is not supported by any of Leonardo's writings, and its proportions do not match the golden ratio precisely. The Vitruvian man is likely to have been drawn before Leonardo met Pacioli.

Evidence of collaboration

Many artists attempted to design figures which would satisfy Vitruvius' claim that a human could fit into both a circle and a square. Leonardo may have been influenced by the work of his friend Giacomo Andrea, a Renaissance architect and an expert on Vitruvius. Andrea's drawing features erasure marks, indicating its unique creation. As with Leonardo's Vitruvian Man, Andrea's circle is centered on the navel, but only one pose is included.

Translation of the text

The text is in two parts, above and below the image. The upper part paraphrases Vitruvius:

Vetruvio, architect, puts in his work on architecture that the measurements of man are in nature distributed in this manner: that is a palm is four fingers, a foot is four palms, a cubit is six palms, four cubits make a man, a pace is four cubits, a man is 24 palms and these measurements are in his buildings. If you open your legs enough that your head is lowered by one-fourteenth of your height and raise your hands enough that your extended fingers touch the line of the top of your head, know that the centre of the extended limbs will be the navel, and the space between the legs will be an equilateral triangle.

The lower section of text gives these proportions:

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.

The points determining these proportions are marked with lines on the drawing. Below the drawing is a single line equal to a side of the square and divided into four cubits, of which the outer two are divided into six palms each, two of which have the mirror-text annotation "palmi"; the outermost two palms are divided into four fingers each, and are each annotated "diti".

Provenance

The drawing was purchased from Gaudenzio de' Pagave by Giuseppe Bossi, who described, discussed and illustrated it in his monograph on Leonardo's The Last Supper, Del Cenacolo di Leonardo da Vinci (1810). The following year he excerpted the section of his monograph concerned with the Vitruvian Man and published it as Delle opinioni di Leonardo da Vinci intorno alla simmetria de' Corpi Umani (1811), with a dedication to his friend Antonio Canova.

After Bossi's death in 1815 the Vitruvian Man was acquired in 1822, along with a number of his drawings, by the Gallerie dell'Accademia in Venice, Italy, and has remained there since. After the Louvre requested the drawing for a major exhibition of Leonardo's works to open on 24 October 2019, the Italia Nostra argued that the drawing was too fragile to be transported. At a hearing on 16 October 2019, a judge ruled that the group had not proven that the work was too fragile to travel, but set a maximum amount of light for the drawing to be exposed to as well as a subsequent rest period to offset its overall exposure to light. Italy's Minister for Cultural Affairs tweeted that "Now a great cultural operation can start between Italy and France on the two exhibitions about Leonardo in France and Raphael in Rome."
