Combining the organic dye indigo and the inorganic clay mineral palygorskite in a highly stable chemical hybrid that, unlike indigo, resists attacks by acids, alkalines, and organic solvents and endures without fading, Maya Blue has a rich blue color that has survived for centuries in one of the world's harshest climates. First used at the site of Calakmul in the tropical forest of southern Mexico during the Late Preclassic period, the Maya's abiding hue diffused across Mesoamerica over a period of 1,700 years. It appears on Maya pottery, sculpture, murals, and codices and carries multiple meanings, standing as a symbol for cultural cornerstones such as sacrifice and the rain god Chaak. It was discovered in 1931 at Chichén Itzá, and its composition was a mystery for more than three decades, then questions about its source, how and why it achieved such stability, and how and why the Maya made the pigment persisted even longer.
In Maya Blue, Arnold summarizes ethnographic, archaeological, chemical, and material science research over the last century from an anthropological perspective. This thorough, engaging, and accessible book chronicles the history of this pigment as no work has done before.
