Especially in the world of visual art, where women involved with great artists have traditionally been consigned to the role of "muse." Art hinges on the idea of a single creator, and his or her (but usually his) creative vision: that's why Guernica is art, and those scenic paintings done painstakingly by hand in workshops in China are not. Art historians argue for years over whether a work should be classified as by, for instance, El Greco, or if it was merely done by one of his trainees, because art affirms that the intentions and identity of a work's creator matters. Even in a collaboration, a partnership, as apparently straightforward as that of Christo's and Jeanne-Claude, the temptation is always to ask: but who really thought of that? (And then there is the further temptation to assume that it must have been Christo.) His refusal to play along — look at how he corrected that interviewer — is admirable.
