Clean: A Global History of Bathing and Soap

by bam

A complete, cited history of getting clean, for high school students. You will visit the great bathing traditions of the world, each sophisticated on its own terms: the Indus Valley's Great Bath, Rome's thermae and the oil-and-scraper method that used no soap, the Islamic hammam and the hard olive-oil soap of Aleppo and Nablus, the Japanese bath born of Shinto purification and Buddhist merit, the Finnish sauna, and the Mesoamerican temazcal. Along the way you will learn where soap actually comes from (no single inventor), and you will meet the single most stubborn myth in this whole subject head-on: that medieval Europeans never bathed and had to be taught to wash. That belief is largely false, and this course shows you the real, documented story instead. The verdict is not 'civilized people versus dirty people.' It is many different, richly developed traditions, plus one specific European retreat from bathing and its slow return. Every claim names a source, and where a vivid story rests on a single observer, the course says so and hedges rather than dressing it up as fact.
