Heritage
Red ochre is among the oldest pigments in the human visual record. Ochre reds lie beside burials at Qafzeh, Israel, about 100,000 years old; red ochre and costly cinnabar lit Pompeian walls; cinnabar was prized from Rome to China. Madder, kermes, and later New World cochineal built fortunes before synthetic alizarin arrived in 1869 and collapsed the madder market almost overnight.
