Art is a complicated, elusive thing to define. I visited New York's Museum of Modern Art one time with a good friend who is an art historian. I stopped him at a Jackson Pollock, a mish-mash of overlapping lines on a gray canvas, and asked him what he'd say about the piece to his classes. "Actually I start my class with this work," he said. He said he begins the discussion of what art is by asking everyone how they would show "creativity." How would they paint or sculpt or video something, some piece, to illustrate that. They talk. Then her turns to this painting. Which, looked at one way, is a timeline of Pollock's creation. You can follow it as it evolves. This line, that line. Going in circles, crossing left to right etc. And then he floated the idea that the untitled painting was simply Pollock showing what "creativity" is. I don't know. Not my territory, but thought I'd share.
Meanwhile I don't know if that dumb sculpture is art or not. But I like the idea of putting any longhorn to work.
