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.
2-Malinalli is the second 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 Malinalli (Grass) is governed by Patecatl as its provider of tonalli (Shadow Soul) life energy. This day signifies tenacity, rejuvenation, that which cannot be uprooted forever. Malinalli is a day for persevering against all odds and for creating alliances that will survive the test of time. It is a good day for those who are suppressed, a bad day for their suppressors.
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.
