Excerpt from Rees's Cyclopedia (1819) giving a historical account of the art of dyeing, from its obscure origins through antiquity, the Middle Ages, and early modern Europe. It covers the legends and uses of Tyrian purple, dye materials known to the Greeks and Romans (alum, alkanet, madder, woad, indigo), the discovery of archil and kermes scarlet, the Gobelin family, and the development of dyeing theory in France, including Berthollet's work. A short closing section lists the various trades that use dyeing or coloring, such as bleaching, staining wood and leather, and marbling paper.
