Pirates! Kings! Beautiful ladies! Daring spies! Elements essential for a page-turning action/adventure thriller, yes, but who would think they'd turn up in a scholarly examination of a little-known substance called cochineal? It is responsible for producing that elusive shade of red deemed vital for dyeing royalty's robes, and the quest for this coveted resource involved some of history's most infamous episodes and ignoble scoundrels. Native to Mexico, the scale insect cochineal was first harvested as a dyestuff by the ancient Aztecs, and once its properties were discovered by European conquistadors, it became the quarry in an international race to obtain a monopoly on its production. As first Spain, and then England, France, and Holland entered the race to procure this precious commodity, nothing less than the way in which the New World was conquered and the Old World prospered was at stake. The granddaughter and great-granddaughter of dyers, Greenfield combines the investigative prowess of a detective with the intellectual reasoning of an academician to create an eminently entertaining and educational read.
