エジプト中王国
Inscribed pottery shards from the Middle Kingdom of Egypt (2000–1800 BCE), found near ancient Thebes (now Luxor, Egypt), list three human genders: "tai" (male), "sḫt" ("sekhet") and "hmt" (female). "Sḫt" is often translated as "eunuch", although there is little evidence that such individuals were castrated.
