From footnote in Jean-Luc Nancy’s The Ground of Image: “In the nineteenth century, the color was prepared using the remains from mummies, refers to a dark reddish brown (‘‘resulting from the final operations carried out with iron oxide, it is one of the red tones of this metal. It is quite close to English, Venetian, or Indian reds,’’). The term has its origins in alchemy, where it referred to the final residue of a chemical operation, ‘‘that phase of the work when everything seems rotten yet when everything is regenerated.’’
