Napoleon once wrote in a love letter to Josephine 'I return to Paris in five days. Stop washing.' To smell like a human was not always the misdemeanour it is today. Body odour was in fact an important factor of sex and courtship, considered by some to be a powerful aphrodisiac, as we see in Napoleon's letter. Contrary to what we like to think, no bodily odour is innately disgusting, instead it is our noses which adapt to fit our beliefs. The Romans would bathe in company and daily. Later, Europe underwent four centuries without a bath. Was it the threat of diseases like syphilis that it feared in the soapy water? Religion links the act of washing with forgiveness and regeneration. We wash the bodies of dead loved ones because somehow we imagine it as the end of the old and the beginning of the new. The history of washing our bodies reveals much about our intimate selves, about how we want to be seen and what we desire most... In this gripping new history, Ashenburg searches for clean and dirty in plague-ridden streets, hospitals, battlefields and makeshift water closets. In the bizarre prescriptions of history's doctors, the eccentricities of famous bathers and the hygienic peccadilloes of great writers we see the twists and turns that have brought us to our own, arbitrary notion of 'clean'.
