I began working on this series in 2000. The initial spark was a photo from National Geographic that astronauts had taken from outer space of huge manmade circular farms centered on wells in the Sahara desert. I loved the way the image functioned: it was abstract yet also literal, remote as well as personal. These paintings were made with watercolor, gouache and acrylic on paper or absorbent ground. They are sealed with an archival varnish, which protects them from moisture and UV rays.
