The Reason Japanese Samurai Shave the Top of Their Head

The practice of “chonmage” (pronounced “chon-mah-geh”) which means “tied knot on top” in Japanese is the reason Japanese samurai shaved the tops of their heads, in a pattern reminiscent of male pattern baldness. Japanese Samurai shaved the top of their heads in this particular style for both pragmatic and symbolic reasons. The shaved portion of the head helped secure their helmets referred to as “kabuto” which means “helmet” in Japanese, making them more comfortable but also prevented overheating during battle. Over time, the chonmage became a status symbol within Japanese society, symbolically representing a samurai’s loyalty and discipline. The chonmage aesthetic also reflected the samurai’s adherence to Bushido, the warrior code. Different variations of chonmage emerged within Japan over the centuries, with the style remaining a distinctive hallmark of the samurai class until the Meiji Restoration in 1868 when Japan modernized and abolished the traditional feudal samurai system

The Toxicity of Tanneries During the French Revolution

One of the largest contributors to pollution during the French Revolution was the work of tanneries, which converted what is essentially animal skin, into leather goods. First the hide was immersed in an alkaline lime and water solution for up to 3 weeks, then it was brought out and shaved for both the hair on one side of the hide and the dissolved fat referred to as “sinew” on the other side. Once this process had been complete, dog and bird feces were mixed with hot water and human urine to create a bacterial cocktail which would work together to soften the hide and help it absorb dye. All of these components were dumped into local water sources once they had served their purpose which made living around them nearly impossible, with many people developing ulcerative lesions upon their throats when around these ingredients for extended periods of time
