Air

A day at a symposium on American Art pre and post 1945 - i.e., was or wasn't that year a dividing line - ought to have filled me with ideas - and indeed it did, particularly about how important air was to art in the second half of the C20th.   I'm not quite sure how I got to that conclusion, unless it was via images of Alexander Calder's mobiles (which brought home to me the fact that I'd never asked the question, before I learned that AC was the answer - who invented the mobile).   But maybe it's just that the air here is clear at last - though one can still see the little lines of flames, at night, of the Las Conchas fire.
