One thing that always strikes me when the long progression of wikipedia-clicks takes me from something like 'Tumulus' all the way to 'Mixtec writing' or, more specifically, 'Codex Zouche-Nuttall' is the divers array of colors through which the early Mesoamericans decorated and illustrated their documents. However, I have never before seen any reference anywhere to the ink they used. Thus, I pose unto ye the following:
From what did they extract their ink?
Did they crush and work lapis lazuli to get blue, as did the Afghans? Did they grow dye plants and extract therefrom their dyes? I am most fascinated by these documents, but the bulk of my fascination is dedicated not to the images themselves, but to that through which the images were created.
