Advance Praise

  • In this wonderfully vivid study we enter an eighteenth-century labyrinth of mirrors, in which the boundaries of sex/gender are blurred and then refracted through espionage, intrigue and courtly adventure. Conlin reminds us of the timeless complexity and elusiveness of identity.

  • By far the best, most humane and deeply-researched account we have of the most celebrated personality of the age of Enlightenment and Revolution, who was baptised a boy but thought otherwise.

  • Conlin does not steer away from the complexities that made D’Eon’s identity possible: political plots, celebrity culture, and forgery. All were conducive to a story of self-fashioning we need now more than ever.
