The significance of this day
Aztec facts
Tenochtitlan, the Aztec capital was captured by Hernán Cortés on August 13, 1521 (day 1-Coatl). This date, as recorded by Fray Bernardino de Sahagún, provides an anchor for the correlation of the calendar.
6-Cozcacuauhtli is the sixth day of eight days in a row specially associated with pulque, the alcoholic beverage made from the fermented sap of the maguey (agave) plant (octli).
Day Cozcacuauhtli (Vulture) is governed by Itzpapalotl as its provider of tonalli (Shadow Soul) life energy. Cozcacuauhtli signifies long life, wisdom, good counsel and mental equilibrium. It is a good day to confront the discontinuities, disruptions, failures and deaths one suffers in life. Cozcacuauhtli is a day for tricking the Trickster.
The thirteen day period (trecena) that starts with day 1-Ozomahtli (Monkey) is ruled by Patecatl. The 13 days of this trecena are influenced by the quest for cures of all the various ills that befall us: the quest to obtain power that can overcome misfortune lies at the heart of the warrior's purpose. The transformation of poison into medicine, and evil into good, is an art whose expression must be tailored to the field of battle. These are good days to fashion a war shield and collect articles for your medicine bundle; bad days to allow infections to fester.
