12. The symbols and hieroglyphics which designated the 20 

 days were the following : 



1. Cipactli — sea animal. II. Ozomatli — ape (female). 



2. Ehecatl — wind. 12. Malinalli — twisted plant. 



3. Calli — house. 13. Acatl — cane. 



4. Cuetzpalin — lizard. 14. Ocelotl — tiger. 



5. Cohuatl — serpent. 15. Quauhtli — eagle. 



6. Miquiztli — death. 16. Cozcaquauhtli — Mexican eagle. 



7. Mazatl — deer. 17. Ollin — sun's movements. 



8. Tochtli— rabbit. 18. Tecpatl— flint. 



9. Atl — water. 19. Quiahuitl — rain. 

 10. Itzcuintli — dog. 20. Xochtli — flower. 



Of these 20 days they composed their second calendar with such 

 a disposition that they formed out of them a period of 260, not 

 reckoning them from 1 to 20, as in the months of the first calen- 

 dar, but from 1 to 13, and in this manner they divided the 260 

 days into 20 "tridecnas," which were after the fashion of our 

 weeks, that each of these days carried with it its numerical char- 

 acter, in order to distinguish the symbols of one set of tridecnas 

 from those of the others wherein they were repeated. These 

 tridecnas represented the daily movements of the moon from east 

 to west, from the time of conjunction until a few days after full 

 moon, which interval of time, while, if it appeared at night above 

 the horizon, is named Ixtozoliztle, or "watching," and after, when 

 it begins to be hidden at night, until near conjunction, when it is 

 visible by day in the heavens, it is called Coehliztli, or "sleeping," 

 as they supposed it then slept at night. By the combination of 

 these tridecnas and the solar cycle of 52 years, they formed a semi- 

 solar period, most exact, for the purposes of astronomy, at the end 

 of which you find verified the similar celestial phenomena which 

 depend upon the movements of the sun and the moon, as the con- 

 junctions, quadratures, oppositions and eclipses of both planets, 

 whose period is contained in a species of calendar that was ob- 

 tained by P. Fr. Diego Valdes, but he does not explain anything 

 about it. In my work already referred to, I demonstrate the ex- 

 actitude of this period, and give an extensive explanation of it, 

 verified byjeclipsesj|that have|Jbeen observed in the years passed, 

 as well as those calculated for the future.
