She explores the physiology of the human swallow, and the 'poignant and baffling' psychology that compels people to ingest non-nutritive things. It also describes the Chevalier Jackson Foreign Body Collection in a museum in Philadelphia. A strange and marvellous story that is also the story of the father of endoscopy.
Combining original research with a sympathetic and evocative sensibility, award-winning author Mary Cappello restores the narratives, lives and desires of the physician-artist Dr. Chevalier Jackson and his patients that haunt the uncanny collection of items which have been swallowed (both accidentally and deliberately) at the world famous Mutter Museum. Swallow journeys deep into the nature of human experience, both as a literary and psychological exploration which uncovers rather than gawks at sword swallowers and women who lunch on hardware.
