Pero los planetas son las tzitzimime o tzontemoc, "los que cajeron de cabeza", es decir, los que parece que caen por el poniente, distinguido su curso del movimiento de conjunto de las otras estrellas. |
  | But the planets are the tzitzimime or tzontemoc, "those which fall from the head," that is to say, which appear to fall in the west, marking their course by moving around the other stars. |
Son ellos los que transformados en tigres en la terrorifica noche del fin del siglo, bajaran a la tierra convertidos en fieros y devoraran a los hombres. |
  | They are the ones who, transformed into jaguars on the terrifying night of the end of the century, will come down to the earth converted into furious beasts to devour men. |
-- Alfonso Caso, El Pueblo del Sol, p.53-54.
N.B.: The Aztec "century" was 52 years.
N.B.#2: This month (August 2000) Venus is again reappearing as Xolotl (the evening star of Quetzalcoatl) as happens almost every two years, as happened when Cortes attacked Mexico in 1519.
