She was a daughter of Epcoatzin, a great lord of Tlatelolco. And Ahuitzotzin and Tecapantzin begot and thence was born only one [son], Quauhtemoctzin, ruler of Tenochtitlan and Tlatelolco. The Spaniards imprisoned him when the Mexica Tenochca state was destroyed on the feast day of St. Hippolytus Martyr, 13 August 1521. And later he died in Huey Mollan; there [the Spaniards] hanged both him and don Pedro Tetlepanquetzatzin, ruler of Tlacopan. Don Hernando Cortéz, Marquéz del Valle, sentenced them on the basis of a lying statement when he took all the rulers there. This account was taken from a painting that don Alonso Jimenéz, a resident of Culhuacan, left. (central Mexico, early seventeenth century)
