140 BUEEAU OF AMERICAN ETHNOLOGY [bull. 28 



peaii chronologies; but the attempt failed in the most essential points, 

 since Orozco favored the erroneous view that the Mexicans began 

 their years, and therefore also what they called their months, with 

 the days Cipactli, Miquiztli, Ozomatli, and Cozcaquauhtli. 



In order to make the matter clear, I will mention still another point 

 of agreement. In the Seventh Relation of Chimalpahin (page 188 

 of Remi Simeon's edition) we read that the entrance of Hernan 

 Cortes into Mexico and his reception by the kings of the three allied 

 kingdoms, Mexico, Tetzcoco, and Tlacopan, took place on the day 

 chicuey Ehecatl, " 8 wind ", the ninth day of the month Quecholli : 

 " ypan cem ilhuitlapohualli chicuey ehcatl, auh yn ipan ynin metz- 

 tlapohual catca huehuetque chiucnahuilhuitia quecholli ". We have 

 also a statement in regard to the same day in the Aztec account which 

 is preserved in the Sahagun manuscript of the Biblioteca Lorenziana. 

 This latter account agrees with the former in stating that the coming 

 of the Spanish occurred in the year ce Acatl, " 1 reed ", on the 9th of 

 the month Quecholli — or, as the author says, on the eve of the 10th 

 of the month Quecholli — but it differs from it in saying that this day 

 was not designated as a day " 8 wind ", but as ce Ehecatl, " 1 wind", 

 and that would be a day 20 days previous to the other : " auh in 

 izquilhuitico in Mexico in ic calaquico in Espaholes: ipan ce hecatl 

 in cemilhuitlapoalli : auh in xiuhtonalli ce acatl, oc muztla tlamat- 

 lactiz quecholli : auh in cemilhuitique ome calli : vel iquac in tlama- 

 tlactli quecholli ". If Ave consult Spanish historians we find, in Ber- 

 nal Diaz del Castillo's Ilistoria Verdadera, the day of the Spanish 

 entrance given as November 8 of the year 1519. 



The writer of the account in the Sahagun manuscript continues 

 his computation from the date given above by counting each month, 

 to which fact I would call attention here. This was, no doubt, the 

 usual historic chronology, for on page 136 of Codex Vaticanus A 

 we see the months which elapsed during the stay of the Spaniards in 

 the city similarly set down. The writer of the Sahagun account 

 reckons in this wa}^ to the feast Toxcatl, when Alvarado fell upon the 

 unarmed Mexicans decked for the feast and slaughtered the flower of 

 the Mexican nobility, and then onward to the feast Tecuilhuitontli, 

 that is, the completion of the month Tecuilhuitontli. On this day. 

 he says, the Spanish fled by night from the city : " Niman quival- 

 toquilia tecuilhuitontli, ie oncan in quizque, vel ipan in ilhuitl in 

 quizque in Espanoles in moioalpoloque ". There were altogether, 

 he says, 235 days, that is, 195 days during which the Spaniards and 

 Mexicans were friends and 40 days during which they fought each 

 other. Computed accurately this can not mean the feast Tecuilhui- 

 tontli itself, but the eve of the feast. For counting 235 days from 

 the ninth day of the month Quecholli we come to the 19th and not to
