To keep collections from languishing, Anne-Marie Bouttiaux set them in motion, multiplying the gazes, perspectives, and horizons from which they are explored. Not only has she made masks dance; she has danced with them. We no longer speak of, or since, but with. The body is the place of knowledge, and dance the desire that moves it. The anthropology of dance should not be taken as a specialised discipline focussing its attention on a specific practice known as dance. It refers to a technique of producing knowledge that develops within and through experience, that Nietzsche calls the gay science . This liber amicorum pays homage to her exceptional career, during which she brought both daring and care to her combined roles as conservator, author, book editor, exhibition curator, and researcher. All the contributions to this book discuss themes that nourished and fuelled her work.
