person asked me whether I came from Tlapallan. I did 
not then understand the meaning of this question ; but 
I afterward knew, that the Indians took us for the 
descendants of QuetzalcohuatF’ (Torq. tom. 2, p. 53). 
It is no doubt interesting to treasure up the most mi- 
nute circumstances relative to the life of this mysterious 
personage, who, belonging to the heroic times, was 
probably anterior to the Toltecks. 
Pestilence and destruction of the Toltecks in 1051. 
They push their migrations farther to the south. Two 
children of the last king, and some Tolteck families, 
remain in the country of Anahuac. 
The Chichimecks, issuing from their country Ama- 
quemecan, arrive in Mexico in 1170. 
Migration of the Nahuatlacks (Anahuatlacks) in 
1178. This nation contained the seven tribes of 
Socbimilcks, Chalcks, Tepanecks, Acolhuans, Tla- 
huicks, Tlascaltecks, or Teochichimecks, and Aztecks 
or Mexicans, who, as well as the Chichimecks, all 
spoke the Tolteck language (Clav., tom. 1, p. 151, 
tom. 4, p. 48). These tribes called their country 
Aztlan, or Teo-Acolhuacan, and declared it to be near 
Amaquemecan (Garcia, Origen. de los Indies, p. 182 
and 502). The Aztecks had migrated from Aztlan, 
according to Gama, in 1064 ; according to Clavigero, 
in 1 160. The Mexicans, properly so called, separated 
themselves from the Tlascaltecks and the Chalcks in 
the mountains of Zacatecas (Clav., tom. 1, p. 156 
Torq. tom. 1, p. 87 ; Gama, Descripcion de dos Pie- 
dras, p. 21). 
Anival of the Aztecks at Tlalixco, or Acahualtzinco^ 
in 1087 ; reform of the calendar, and first festival 
of the new fire, since the going out from Aztlan, in 
1091.
