Treasured by the ancient Mexicans, cochineal was sold in the great Aztec marketplaces, where it attracted the attention of the Spanish conquistadors in 1519. Shipped to Europe, the dye created a sensation, producing the brightest, strongest red the world had ever seen. Soon Spain's cochineal monopoly was worth a fortune. Desperate to find their own sources of the elusive dye, the English, French, Dutch, and other Europeans tried to crack the enigma of cochineal. Did it come from a worm, a berry, a seed? Could it be stolen from Mexico and transplanted to their own colonies? Pirates, explorers, alchemists, scientists, and spies—all joined the chase for cochineal, a chase that lasted more than three centuries. A Perfect Red tells their stories—true-life tales of mystery, empire, and adventure, in pursuit of the most desirable color on earth.
