Posted by: Katherine Ashenburg - Author of The Dirt on Clean

Often it’s hard for me to remember where I first got an idea for an article or book. But in the case of The Dirt on Clean, I can pinpoint it exactly. In the spring of 2003, Toronto (where I live) was the city outside Asia that was hardest hit by SARS. I was washing my hands 10 times more than usual and ruminating about the connection between washing and disease. At the same time, I happened to visit the 18th century rooms in the Royal Ontario Museum. A painting of a crowd was captioned, “The aristocrats in this picture are just as dirty as the peasants.” I don’t usually listen to audiotapes in museums, but I pressed the button and listened to a short tape on the subject.

What I learned was that the medieval Crusaders brought back the custom of bathhouses from the Near East. Medieval folk bathed together in communal baths, until the plagues frightened them into believing that sickness entered the skin through water. Most of the bathhouses closed by the 15th century and for the next couple of centuries, Europeans shunned water, wiping hands and faces without soap, and leaving the rest untouched. Wearing white linen, or “the linen that washes,” as it was called, substituted for real washing.

Listening to this, the proverbial lightbulb went on. By its light I saw a book title: Clean: The History of a Notion. The title evolved. But my sense of an intriguing subject, centred on the body but with connections to sexuality, disease, religion and other “big” ideas, remained pretty constant. I owe the ROM a thank you.
