James Elkins is a tireless advocate for seeing—not just looking, but seeing. A professor at the Art Institute of Chicago, Elkins writes books about art that anyone, artist or otherwise, will find compelling. His books (there are nearly 20) range from How to Use Your Eyes, Pictures and Tears: A History of People Who Have Cried in Front of Paintings, to Why Art Cannot Be Taught: A Handbook For Art Students.
This fall Elkins has done four posts on Huffington Post addressing a variety of art related topics like How to Look at Mondrian, How Long Does it Take To Look at a Painting?, Are Artists Bored by Their Work? and Looking at the Sky. Ice Halos: Divine Signals Or The Ultimate Art Installation?
There is much to be said in response to each of these postings. But given the recent snow storm that passed through Boston, this last topic is of particularly interest. After reading his article I feel as if I have been given a whole new set of tools with which to look at the winter light and sky.
Why choose ice halos? Why not start with landscapes, faces, or bodies–things that are more common in art? Because ice halos are a spectacular example of our blindness…ice halos are the exotic winter cousins of rainbows: both are caused by water suspended in clouds, but ice halos appear when the water has frozen into tiny crystals.
The halo [pictured] is called the twenty-two degree halo. (It should have a more spectacular name, but that’s science for you.) It appears mostly in the wintertime, when it is very cold and the air is dry…The twenty-two degree ice halo is very large; it is a different creature from the aureoles and brownish-blue coronas that sometimes form just around the sun or moon. Twenty-two degrees is double the spread of your hand at arm’s length, so the halo is a little overwhelming, as if it were somehow very close to you.
Elkins goes on to elucidate a variety of light phenomena that we have to train our eyes to see such as twenty-two degree parhelia, or “sun dogs,” and sun pillars. In researching this phenomenon Elkins read up on the scientific explanations. But his conclusions are similar to ones I have come to as well:
A number of physicists have worked on understanding ice halos, and in 1980 Robert Greenler wrote a book that explains virtually all of them…But in the end, it is a little sad to see nature explained so efficiently, so ruthlessly. My favorite parts of Greenler’s book are the moments when he admits defeat. I don’t mind the science: it’s interesting, but it has very little to do with the experience of looking. Sometimes I read about the latest observations and research, and other times I am more interested in what Keats called negative capability: I suspend my desire to understand all these things in terms of hexagons, reflection, and refraction. I no longer believe that my fascination is answered by diagrams of ice crystals.
No, diagrams don’t do it. Not in the least.
