The Spaniards pushed on toward Tenochtitlan, coming down out of the mountains by way of Tlalmanalco. Shortly after their descent, Prince Ixtlilxochitl of Tezcoco (brother of Cacama, the lord of Tezcoco) left his city with a group of followers to greet Cortes in peace.
The Codex Ramirez preserves a few fragments in Spanish of an older, indigenous account of this episode, of which the Nahuatl original has been lost. According to this account, it was Prince Ixtlilxochit1 who persuaded the people of Tezcoco, resentful of Aztec domination, to join forces with the conquistadors. The same account states that Cortes then visited the city of Tezcoco, but this statement is not corroborated in any other source. Bernal Diaz delCastillo, Sahagun's informants and Fernando de Alva Ixthlxochitl do not mention such a visit; they say only that the Spaniards marched to Ixtapalapa and from there to the Aztec capital.
The Codex Ramirez contains several anecdotes of interest and importance, especially the reaction of Yacotzin, the prince's mother, when her son asked her to change her religion. It also describes how Motecuhzoma responded to the news that the Spaniards were approaching Tezcoco. He ordered a last meeting of his chiefs, to discuss whether the strangers should be welcomed or repulsed when they arrived at Tenochtitlan. Despite Cuitlahuac's gloomy predictions, he finally decided to receive them in peace.
