The compelling thing about making art — or making anything, I suppose — is the moment when the vaporous, insubstantial idea becomes a solid there, a thing, a substance in a world of substances. Circe, Nimbue, Artemis, Athena, all the old sorceresses: they must have known the feeling as they transformed mere men into fabulous creatures, stole the secrets of the magicians, disposed armies: ah, look, there it is, the new thing. Call it a swine, a war, a laurel tree. Call it art.
