L'art de l'indigotier
L'art de l'indigotier is an 18th-century French technical manual on indigo cultivation and processing, published in Paris in 1770 by De Beauvais-Raseau for planters and dye producers. Its engraved plates show indigo plants with roots and leaves, and the vats, troughs and mills used to extract and process the dye, drawn in clean, precise linework that suits diagrams, botanical sketches and historical process illustration.
