I am only trying to teach you to see …

Reading back through my last post recalled a visit to an exhibition of Leonardo da Vinci’s anatomical drawings at the Queen’s Gallery, Buckingham Palace about a year ago. The blend of art and science in these small but highly detailed drawings gains added piquancy because the motivation, albeit somewhat obliquely, was partly religious: a better understanding of anatomy fuels Leonardo’s artistic endeavours which, mostly, result in paintings with a devotional context (The Last Supper, Madonna of the Rose …). Leonardo would have been perplexed by our modern divisions between the arts and sciences (C.P. Snow’s Two Cultures etc.) and by the science and religion divide perpetuated by Dawkins and others.

The struggle I had had with the anatomy of chironomid larvae mirrored Leonardo’s own explorations of the human body. The cultural significance of these drawings is that his own observations were replacing, and sometimes challenging, the notions handed down from Galen and other classical authorities. Yet even Leonardo was not a totally dispassionate observer of the human body: the exhibition notes examples where his drawings included non-existent elements borrowed from classical books whilst his famous drawings of human embryos are based, in part, on bovine anatomy. As I tried to capture the chironomid mouthparts, I was moving between direct observation and illustrations and diagrams in textbooks. The latter informed my interpretation of the former but, at the same time, there is a real risk that I might carry any errors from these diagrams into the interpretation of my own observations.

Perhaps the fault lies with us, looking at Leonardo’s drawings with a 21st century perspective and forgetting the constraints under which he worked? These pictures are the result of close observation of unembalmed human corpses in Milan. Working in winter made the task slightly easier but the benefits were offset, to some extent, by shorter days.  Animal corpses were much more widely available, hence the occasional tendency to extrapolate from bovine to human anatomy.

Drawing is a useful reminder of how far science – even ecology – has drifted from observation, and how quantification is, too often, an abstraction of reality as anything that can’t be counted or measured falls off the agenda. I’m reminded of Ruskin’s statement about the motivation behind his drawing classes: “I am only trying to teach you to see”.
