Reed (Acatl)

Acatl, the reed, draws its ordinary augury from the plant's hollow stem: the reed is hollow, and the readers made that the day's meaning directly, with Sahagun's informants describing the reed born as empty at heart, unstable and talkative, needing discipline to come to anything worthwhile without it, one of the more frankly unflattering readings the Florentine Codex records for any of the twenty signs. Yet 1 Acatl carries a significance the plain augury does not capture: it is the calendar name of Quetzalcoatl himself, and the day and the year it can open carry his memory specifically, a naming Sahagun and other colonial era sources connect to the feathered serpent's own legendary departure from Tollan and the promise, recorded in chronicles written down decades after the Spanish conquest, that he would return in a year bearing this same name.

Modern scholarship treats the precise relationship between this prophecy tradition and the year 1519, when Spanish forces under Cortes arrived, as considerably more complicated than the colonial narrative suggests, since the surviving accounts of omens and expected return were largely set down after the conquest itself and may reflect Nahua and Spanish narrators making sense of catastrophe together rather than a belief reliably attested before contact, a genuinely debated point among historians rather than a settled one.

Acatl's patron in the day sign count is Tezcatlipoca, the smoking mirror, whose severe, testing character across his several manifestations sits somewhat uneasily beside the reed's hollow, talkative augury, though his patronage here is recorded plainly in the sources without further comment connecting the two. Its direction is east, and as one of the four year bearer signs Acatl specifically names the years of the eastern quarter across the fifty two year Calendar Round, the same span of years the sign's connection to Quetzalcoatl's calendar name made especially freighted with meaning in the colonial era retellings of the conquest period.

The mechanics of year bearing follow the same arithmetic for every one of the four signs: 365 days exceeds an even multiple of twenty by five, so each solar year's opening day sign advances five places from the year before, and since twenty divided by five yields four, only four signs spaced exactly that far apart, Calli, Tochtli, Acatl and Tecpatl, ever recur as year openers. An Acatl year, carrying both the reed sign's ordinary hollow augury and its extraordinary association with Quetzalcoatl's name, would have been read by the tonalpouhque as a year of particular consequence, whatever number among the thirteen possible it happened to carry.
