tlacuilolli (FCbk11f216r)

The pre-contact book was screenfolded, so this type of book was a European colonial introduction. The many examples below of books show the wide array of Nahual terminology that could apply. Books often had associations with the Catholic church, as something priests might hold while giving mass or when instructing the doctrine. Or, church singers might hold books while they sang, for example. The paper could be European or Indigenous (amatl).

Marc Thouvenot identifies the verb icuiloa (or ihcuiloa, with the glottal stop), which means to paint, write, or print, as having a root of -cuil-. He notes how it also appears in tlacuiloliztli (writing), tlacuilo (writer), and cuicuiltic (mottled). He goes on to show various uses of icuiloa that take it beyond the simple definitions just given, resulting in something like the action of creating a design (e.g., on leather, ceramics, sculpture, or in textiles). It can also be something like the action of decorating (e.g., to put a flower on a cup of atole). He associates icuiloa and tlacuilolli with "cultural artifacts," such as arts and crafts or examples of writing and painting, but cuicuiltic with effects created by "nature." This short summary barely does his article justice; it is worth reading the entire piece. How Thouvenot's study might connect with the concept of bent or curved mentioned by Prem (1974: 555, 682) raises an interesting question. Perhaps the bent or curved lines of writing, painting, carving, embroidery, and so on, fall with in the realm of expressions of -cuil-. See
