Lords of the Night

A Lord of the Night entry records one of nine deities who, in the Aztec and wider Mesoamerican calendar, rule successive nights in an unbroken nine day cycle running independently of both the two hundred and sixty day tonalpohualli and the eighteen veintena solar year, as the colonial era Nahuatl annals gathered in the Codex Chimalpopoca record them.

An entry records a lord's documented place in the nine night sequence and the deity's own broader documented character, since the nine night cycle is a separate structural layer of the calendar rather than a subset of either the day sign count or the veintena feast cycle, and conflating the three obscures a genuinely distinct system.

The Codex Chimalpopoca is a scholarly translation by Nahuatl specialist John Bierhorst of an annals compilation written down generations after the conquest by Nahua scribes preserving older oral material, so an entry cites it for what the tradition itself records of this cycle, honestly noting the layered, uneven nature of the underlying compiled text rather than treating it as a single uniform eyewitness source. An entry also records, where Bierhorst's translation allows it, how a given lord's documented character in this nine night role compares with that same deity's broader documented character elsewhere in Aztec religion, since the two are not always identical in emphasis.

The Aztec Calendar Stone, the large carved basalt monument documented by the Getty Research Institute among others, prominently displays day signs and calendrical bands recording the tonalpohualli, a documented public, monumental record of that particular system in a way no comparable stone survives for the nine night lords.

That documented absence is itself informative for a Lord of the Night entry: it shows the nine night cycle was recorded and transmitted differently from the day sign count, through the annals tradition rather than through public monumental carving, and an entry notes that honestly rather than assuming every part of the Aztec calendar was documented the same way or with equal public visibility.

A Lord of the Night entry therefore draws its evidence from the textual annals tradition specifically, while noting, where the calendar stone's own documentation is relevant, what that separate monumental record does and does not depict, since the two are genuinely different kinds of surviving evidence for two structurally distinct calendar systems that operated side by side. The Getty volume's own essays also document how the stone's public, monumental purpose, tied to state ceremony and dynastic legitimacy, differed from the private, priestly transmission the nine night cycle instead relied on, a documented contrast in function as well as in medium.
