“Give me a field and it’s pure inspiration,” sculptor Thomas Sayre says. He likes stainless steel, sure, but at the moment, Sayre is into earthcasting, in which he “digs holes in Mother Earth, pours or sprays concrete into their shapes, and then stands them up against Father Sky.” Sayre wants to marry human intention and the grain of nature, which means that a 16-foot-tall, 30,000-pound piece is “small and intricate” for this artist who uses complex detailing and structural engineering to build his creations. Oh, and a very large crane.
