Deepak and I had a debate about the stringency of the Hawaiian kapus. Here, from the Wikipedia page (trustworthy!) on Kalanikauikaʻalaneo Kai Keōpūolani-Ahu-i-Kekai-Makuahine-a-Kama-Kalani-Kau-i-Kealaneo, the highest ranking wife of Kamehameha I: “She possessed the kapu moe (prostrating taboo) which required commoners to fall to their face on the ground at her presence. When chanters mentioned her name, listeners removed their kapa (bark cloth) garments above the waist in deference. Even the touching of her shadow by commoners was punishable by death.”
Life goal: co-opt this excerpt for my own posthumous Wikipedia page.
