Chiconcuauh (MH648r)

The cuauhtli is a day name in the 260-day divinatory calendar called the tonalpohualli. So, this is a calendrical name. But, interestingly, the companion number for the eagle is disguised as a ceramic pot rather than some number of dots or lines, as the number would have been represented in earlier times (and still found in places in this manuscript). Calendrical names, while still popular among tribute paying Nahuas, were in a notable state of flux, sometimes with the numbers dropping away completely and sometimes appearing only as numbers (with the calendrical day name dropping away). Whether this was a natural evolution or erosion of old naming patterns, or represents some effort to suppress a lingering tradition that was connected to Nahua religious belief remains to be seen.
