This reference to the Quetzalcoatl myth at the commencement of the Maya chronicle needs not surprise us. We encounter it also in the Kiche _Popol Vuh_ and the Cakchiquel _Memorial de Tecpan Atitlan_. These members of the Maya family also grafted that myth upon their own traditions. As history, it is valueless; but as indicative of a long and early intercourse between the Maya and Nahuatl speaking tribes, it is of great interest. As this question will also recur in reference to various later passages in the Maya chronicles, I will discuss it here. One of the earliest historians of Yucatan, the Doctor Don Pedro Sanchez de Aguilar, states that six hundred years before the Spanish conquest the Mayas were vassals of the Aztecs, and that they were taught or forced by these to construct the extraordinary edifices in their country, such as are found at Uxmal and Chichen Itza. His words are: "Fueron tan politicos y justiciosos en Yucatan como los Mexicanos, cuyos vasallos habian sido seis cientos años antes de la llegada de los Españoles. De lo cual tan solamente hay tradicion y memoria entre ellos por los famosos, grandes y espantosos edificios de cal y canto y silleria y figuras y estatuas de piedra labrada que dejaron en Oxumual [Uxmal] y en Chicheniza que hoy se veen y se pudieran habitar." _Informe contra Idolum Cultores del Obispado de Yucatan_, fol. 87 (Madrid, 1639). The vague tradition here referred to was made part of the testimony in a lawsuit at Valladolid, Yucatan, in 1618. These old documents were brought to light by the late eminent Yucatecan historian Doctor Justo Sierra, and Dr. Berendt took a copy in manuscript of the most important points. I think it worth while to insert and translate this testimony. VILLA DE VALLADOLID--AÑO DE 1618.
