More than 500 such sculptures—often full figures with elaborate hairstyles and jewelry— have been found in central Nigeria. Named after a discovery site, Nok culture (500 BCE–200 CE or 1500–1 BCE) produced the earliest large figurative artworks in Africa outside of Egypt. Little was known about their social context, as they were first found in mining deposits in the 1920s. Archaeological excavations conducted in the 2000s by a German-Nigerian team suggest that many sculptures were deliberately broken and placed under pavements and in pits, indicating ritual practice. Male-centered art histories presumed men made these figurative sculptures; however, they incorporate building and firing techniques practiced only by women.
