Then Huitlalotzin spoke to me, don Pablo Ahuachpain. He said: My younger brother, let us follow the discourses of our elders when Tecoxolotl went to Chalco. Let us take him to Oztoticpac. And when Huitlalotzin had thus spoken, Coanacochtzin then went to settle in Oztoticpac in the home of Xilocuechtzin. He did not go to Mexico, to which the Captain had dismissed him. Huitlalotzin held him. (central Mexico, early seventeenth century)
