Untitled 1970

Robert Grosvenor made this, I don’t know exactly when. Here, the artist has created what I would call a three-dimensional painting—a sculpture, in the landscape. It's like, what is that horizontal line doing? I imagine Grosvenor, out in the field, considering it and thinking about it in relation to the horizon. You can feel him wanting to occupy space, but also divide it. It must have been something, to install that piece, to work with those materials, to decide where exactly to put it. This feels kind of like drawing, a big, black line drawing in space. It kind of puts me in mind of the work of people like Richard Serra, or even Barnett Newman. I suppose that’s the ongoing game of artists—answering each other, across time, and working out new answers.
