The name of the ancient capital of which it formed the nucleus was Tullan Cholollan Tlachiuhaltepec.(75) Boturini (_op. cit._ p. 113) cites an old native manuscript on which a picture of the pyramid of Cholula was painted with the note that, in ancient times, it was named Tultecatl Chalchihuatl On Azia Ecatepec, which he translates as “the monument or precious jade stone of the Toltecs, which rears itself in the region of the air.” As eca-tepec literally means air-mountain, Boturini’s translation may seem somewhat exaggerated; on the other hand, the Spaniards, who knew the Nahuatl language best, repeatedly state that its words were so replete with significance that it would sometimes require several Spanish sentences to set forth the meaning of a single native word. Boturini, who had exceptional opportunities for obtaining information, adds to the above the following translation of a Nahuatl inscription which had been written by the native scribe below the drawing which unfortunately is now lost. “Nobles and Lords: Here you have your documents, the mirror of your past, the history of your ancestors who, out of fear for a deluge, constructed this place of refuge or asylum for the possibility of the recurrence of such a calamity.” After citing the opinions of various authors concerning the origin of the pyramid, Orozco y Berra concludes that “there is no certainty about its age, but instinctively it is supposed to be extremely ancient and to pertain to pre-historic times. According to my judgment the people who constructed it belonged to the same civilization as the builders of Teotihuacan and possibly were their contemporaries. Cholollan was also a venerated sanctuary, in which the religious idea predominated” (_op. cit._ p. 363). “At the time of the Conquest a temple stood on the summit of the pyramid and contained an image of Quetzalcoatl (the Divine Twain, the Creator, the Father and Mother of all) as well as an aerolite, shaped like a frog which had fallen from heaven, wrapped in a ball of flame.” In the Vatican MS. of Padre Rios there is another version of the tradition that the pyramid had been erected by giants after a deluge, which had destroyed everything, ... and that before it was finished, fire fell upon it causing the death of its builders and the abandonment of the work. Allusion has already been made, in the preceding pages, to the native traditions according to which, “there had been three memorable epochs in the history of mankind, which lasted for centuries and were abruptly terminated, each time by a mighty convulsion of nature. The majority of human beings perished in each of these, but a remnant survived and thus the race was preserved.”
