For the sculptor, creating a grotesque or gargoyle rainspout is what improvisation is to an actor or jazz musician. It frees them from all the rules they studied about carving. "The stuff I usually do is mostly classical," Arnold says. "But with a gargoyle I can take those skills and kind of loosen up." This grotesque with foliage trickling from his beard and mustache, a horned helmet, and deep set slanted eyes, is a departure from the human form.
