The Nok culture of central Nigeria produced West Africa's oldest known figurative sculpture — hollow, low-fired terracotta heads and figures with triangular, pierced eyes that stare out across twenty-five centuries. Discovered accidentally by tin miners on the Jos Plateau in the 20th century, these forms carry a grainy, pocked patina from millennia in the earth: warm fired russet-orange clay weathered to mottled brown, quartz and mica catching dim light. This design system channels that excavated materiality — a dark earthen museum ground lets the fired terracotta glow, pierced-triangle motifs stand in for ornament, and every surface reads as burnished-then-weathered clay rather than smooth digital gloss.
