How did ancient people wash away grease and dirt before the first soap was invented? Why is ordinary river water powerless against sebum, while quartz sand and caustic stove ash peeled the living skin off hunters' hands?

In this video, we'll explore the dramatic history of soap's invention—from the accidental discovery of Sumerian weavers on the banks of the Euphrates to the cyclopean soap factories of Aleppo and the Roman fulling mills. You'll learn why slaughterhouse waste and campfire ashes became the foundation of global hygiene, why Marseille soap led to royal bans, and the terrible price physician Ignaz Semmelweis paid for trying to force doctors to simply wash their hands before examining patients.
