Notes: These are drawings of the symbols for each of the 20 sacred Aztec days in their lunar calendar. This calendar was the more important of the two interlocking Aztec calendars. Each of the 13 months of this calendar was numbered, 1 through 13, the first four of which were the most significant. According to the Aztecs the days were burdens carried by the gods. Pasztory says this: "Each day sign and number signified a good, bad, or indifferent fortune. Gods and men took their names and destinies from the day of their birth. A woman born on the day 1 Flower would become an embroiderer; a person born on 1 Rabbit would become a drunkard; anyone born on 1 House would come to a bad end as a thief or prostitute. Priests had codices with pictures of the almanac which they consulted for their prognostications. Fate could be ameliorated in certain ways; if a child's naming day happened to be unlucky, it could be postponed for a better one. Some years, such as 1 Rabbit, were entirely unlucky. In Aztec history, droughts were said to occur in years named 1 Rabbit, and good weather in those named 2 Rabbit... The Aztecs believed that there had been four previous worlds which had been destroyed respectively on the days 4 Wind, 4 Water, 4 Jaguar, and 4 Rain of Fire. These worlds ended in catastrophes appropriate to their signs, and each time humanity perished. The Aztecs were living in the fifth world, which would be destroyed by earthquakes on the day 4 Movement" (59-60).
