Rembrandt’s vision

The Netherlands celebrate four hundred years of Rembrandt’s genius.

While looking around for links I noticed this story for the first time:

Margaret S. Livingstone and Bevil R. Conway, neurobiologists at Harvard Medical School, say Rembrandt’s many self-portraits reveal that his eyes are focused in slightly different directions, depriving him of the “stereo” effect that makes vision three-dimensional. As a result, they argue, Rembrandt would have struggled with depth perception – though he may never have known he had a vision defect.

Rembrandt’s flat world view may have helped him more precisely capture reality on a flat canvas, where painters create the illusion of three-dimensions through techniques such as shading. In fact, Livingstone and Conway say that visual artists are far more likely to be “stereoblind” than the general public, suggesting that limited depth perception may actually be an advantage over normal sight.

“Art teachers often instruct students to close one eye in order to flatten what they see,” the researchers write in today’s New England Journal of Medicine, explaining their theory about Rembrandt. “Stereoblindness might not be a handicap – and might even be an asset – for some artists.”

Similar assertions from doctors about conveniently dead artists surface from time to time; we had Michelangelo suffering from Asperger’s recently and I recall a story about Shakespeare having a brain tumour based solely on scrutiny of very vague portraits. The Rembrandt story is significant for me because my eyes have always been mis-aligned and I don’t see stereoscopically. I have permanent double-vision as a result, something people are always surprised to hear, although I only notice this when I think about it. My brain treats the mis-aligned (and weaker) data from my right eye as redundant information and so ignores it.

The point is, whether Rembrandt had a similar defect or not (and I’m sceptical; how can you be so sure by looking at a few paintings?), it’s very difficult, if not impossible, to judge what effect this has on artistic ability without conducting a mass survey. Even then I doubt that you’d discover much. The doctors in this case want to imply that Rembrandt’s damaged eyesight gave him an extra edge with regard to depth perception but I find this incredibly difficult to demonstrate with any degree of certainty. What gives Rembrandt more of an edge (and keeps us looking at his work) is his exceptional drawing skill and peerless mastery of the oil medium, something that’s partly innate talent but mostly prodigious ability and the result of years of labour. Whatever assistance stereoblindness might lend him would be a very small thing next to this combination of natural gifts and hard work.

“One measures a circle, beginning anywhere…”

Robert Hughes writing in The Guardian about Rembrandt this weekend had this to say about one of the painter’s later works:

He had done pictures of himself that fairly radiate a gloating success, but the deepest was saved for the last decade of his life, when he painted himself as a painter at work, holding brushes, palette and maul-stick. He has his back to a wall, or perhaps a large canvas. On the canvas are two large arcs, incomplete circles. What are these abstract forms doing there? They come from Rembrandt’s reading of a well-known and indeed exemplary story in Pliny. The great Greek painter Apelles, so Pliny’s story goes, went to visit an equally famous ancient master, Protogenes, on the island of Rhodes. But Protogenes was out, and so Apelles, rather than leave him a note, drew on his studio wall a perfect circle, freehand. Protogenes would realise that only an artist of Apelles’ skills could possibly have done this. So Rembrandt places himself before the message that compares him to Apelles, king and ancestor of his art. Old age has at last freed him to make an incontrovertible, utterly simple proof of mastery.

This may be an artistic equivalent of one of those ideas Borges discusses in essays such as The Fearful Sphere of Pascal, where he plots the recurrence of the concept of “the circle whose circumference is everywhere and whose centre is nowhere.” The artist version emerges again with the pre-Renaissance painter Giotto:

According to a story related by Vasari, Pope Benedict XI wanted to employ Giotto and sent an emissary to visit the artist. The messenger asked Giotto for a drawing he could submit to the pope, to prove the artist’s worth. Giotto smiled and took a sheet of paper, dipped his brush in red paint, closed his arm to his side, and with one twist of his wrist drew a perfect circle freehand. Giotto handed this drawing to the messenger, who stared back in disbelief. ‘Is this the only drawing I’m to have?’ asked the messenger. Giotto answered, ‘It’s more than enough. Send it along and you’ll see whether it’s understood.’

Several hundred years later, Tom Phillips painted Fifty attempts to draw a freehand circle inspired by Giotto’s example. I remember being told the Giotto story in school art class and we all had a go at drawing freehand circles. It is indeed a difficult business but after a while your arm starts to get used to the motion. Like many things in art, practice is the key.
