Monday Morning Art School: The Canon of Human Proportions

Vitruvian Man, c. 1492, by Leonardo da Vinci.

Throughout history, artists have subjected the human figure to canons of proportion. That means they’ve overridden what they see, in favor of what they think is beautiful or graceful. In fact, in some cultures (classical India, for example), drawing from life was not considered an advantage. And until the age of photography, subjects like squirming infants were difficult to draw.

Every flourishing culture has developed its own canon of proportion. The best known examples are the art of ancient Egyptand classical Greece, both of which had rigid standards of what was true and beautiful.

Marcus Vitruvius Pollio was a Roman architect and civil engineer whose ten-volume de Architectura profoundly influenced Roman building. He believed that beauty derived from nature, with universal laws of proportion and symmetry. He carefully measured the human (male) body, thinking it a model of natural proportional perfection. He demonstrated that the ‘ideal’ human body fitted into both a circle and a square, which illustrated the link between perfect geometry and the perfect body.

Leonardo da Vinci drew Vitruvian Man as a sort of rebuttal to this, since he knew there was no way the circle and square could have the same midpoint on the human form. He used his own measurements and idealized them into a system that’s written across his drawing.

His is, at least to modern eyes, a more beautiful scheme; compare it to an illustration from the 1521 version of de Architectura, which bears an uncomfortable resemblance to a crucified man.

The human measurements I learned as a child in mid-century America.

Fast forward to our own times and our own canon. We’re taught that the human form is between 7.5 and 8.5 heads tall. As a child, I learned that the midpoint of the body is the hipbone, that the line from top of head to chin equals the line from chin to nipple line, from nipple line to natural waist, from natural waist to hips, and then an equal distance from there to the feet.

This of course is the measurement of a long-limbed person. A stockier person will have a bigger head, and the measurement will be more like 7 figures tall.

Tableau Vivant by German actress Olga Desmond, c. 1908. I’ve taken the liberty of adding the hashmarks to demonstrate how variable those proportions are.

Of course, what is considered beautiful changes with the generations. Consider the figure of Olga Desmond, a German dancer who performed nude at the turn of the last century. Even making allowances for her head being tipped down, she is significantly large-headed and short-waisted compared to the ideal of the 20th century. Her legs are three head-units long, rather than four.

Idealized proportions are a useful guide, especially when you’re drawing people from imagination. I probably sketched them a few hundred times as a kid, before I had access to models. They’re also useful for checking your work. If your drawing seems way out of proportion, check it against this standard.

But relying on memorized proportions will lead to lazy, generalized, generic drawings. It’s far better to measure carefully.

This is especially true in our polyglot American culture. A society that idolizes both Emily Ratajkowski and Lil’ Kim has no rigid standards of beauty, and that’s a great thing. The only generalization you can make about Americans is that we’re, by and large, well-fed.

Nothing new under the sun

Leonardo da Vinci’s Vitruvian Man was based on book III of De Architectura. Vitruvius said the human figure was the principal source of proportion for the classical orders of architecture.
The art of hydraulic cement was lost after the fall of the Roman Empire and not rediscovered until 1756, but if people had just read their Vitruvius, the recipes were in there all along.

Sandy Quang (who is writing her Master’s thesis) prefers her Vitruvius aloud so I’ve listened to quite a bit of his De architectura in recent months. He’s such a lucid writer that I have no trouble following it while driving. What’s amazing is how much of what he describes hasn’t changed in almost 2100 years.

Very little is known about Vitruvius’ life. He was born about 80–70 BC and died sometime after 15 BC. He was some kind of praefect, but whether that was in the army or civilian life is not clear. He was mentioned by Pliny the Elder and Frontinus, but even his cognomen (surname) and first names are uncertain.
What an amazing mind Vitruvius had! He not only wrote; he practiced his craft. As an army engineer he specialized in the construction of ballista and artillery. He described the building methods of foreign tribes throughout the Roman Empire, from which it can be inferred that his service was broad. And somehow, he had the time to write this ten-volume treatise on architecture, which is the only surviving classical text on the subject.

Triumph of Neptune standing on a chariot pulled by two ichthyocentaurs, Barthos and Aphros, third century AD. It was built as per Vitruvius’ instructions, and if you were inclined to make one today, you’d use essentially the same technique. (The fundamental absurdity of ichthyocentaurs is not an architecture question, so Vitruvius would have had no advice about whether or not to include them.)
Ancient Roman architects had a broader remit than our modern equivalents, being responsible for engineering, urban planning, materials, HVAC, acoustics, plumbing, and a whole host of other sub-specialties. De Architectura attempts to break down this massive field and describe it in simple, comprehensible terms.
Sandy has read to me from the books on materials and pavements and decorative plasterwork (which relate to her particular interest in Roman mosaics). Having done my share of construction and plastering, I’m pretty familiar with how we use those materials today. Other than adjustments for climate, it’s shocking how little has changed.
An ancient Roman concrete vault in Rome, from the Basilica of Maxentius and Constantine, c. 312 AD. Can we possibly improve on concrete structures that lasted two millennia?
We don’t seem to produce such brilliant generalists in the modern era. I wonder why that is? You can read De architectura here.
