Book excerpt: This wonderfully small, thick book--like a box of photos--is divided up into the following categories: bonds (between partners and family members), icons (say, Jane Fonda as Barbarella), observations of glimpsed love or lust, come-ons to further naughtiness, tokens (mostly flowers juxtaposed with women), libidos (lusty acts), reveries (erotica), and obsessions (the sexual unusual). The international array of photographers includes Man Ray, Robert Mapplethorpe, Nan Goldin, Helmut Newton, Sally Mann, Immogen Cunningham, Brassai, and Julia Margaret Cameron. After a lengthy introduction on the history of photography and desire, there's nothing but photos there-on-in. You might just get aroused, or fascinated as to how others are aroused, or intrigued as to how far people go to arouse others. Ewing is director of the Musee de l'Elysee in Lausanne, Switzerland.
