This town, according to a tradition preserved by Herrera, was founded after the destruction of Mayapan, and, therefore, not more than seventy years before the arrival of the Spaniards. Mayapan was destroyed in consequence of a violent feud between the two powerful families who jointly ruled there, the Cocoms and the Xius or Tutul Xius. The latter, having slain all members of the Cocom family to be found in the city, deserted its site and removed south about fifteen miles, and there established as their capital a city to which they gave the name Mani, "which means 'it is past,' as if to say 'let us start anew.'"[89-1] At the time of the Conquest the reigning chief of the Tutulxius was friendly to the Spaniards, and voluntarily submitted to their rule, as we are informed with much minuteness of detail by the historian Cogolludo.[90-1] We may reasonably suppose, therefore, that this chronicle was brought from Mayapan in the "Books of Science," which Herrera refers to as esteemed their greatest treasure by the chiefs who broke up their ancient confederation when Mayapan was deserted. Hence the records ran a better chance of being preserved in this province than in those which were desolated by war. As I have already said (page 65) a large number were destroyed precisely at Mani by Bishop Landa, in 1562. I find among the memoranda of Dr. Berendt reference to four "Books of Chilan Balam," of Mani. These dated from 1689, 1697, 1755 and 1761, respectively, but I have not learned from which of these Pio Perez extracted the chronicles he gave Mr. John L. Stephens. Dr. Berendt adds that it was from one which was in possession of a native schoolmaster of Mani, who, having the surname Balam, claimed to be descended from the original Chilan Balam![91-1] The first publication of the document was in the Appendix to the second volume of Mr. Stephens' _Incidents of Travel in Yucatan_ (New York, 1843). It included the original Maya text, with a not very accurate translation into English of Pio Perez's rendering of the Maya. From Mr. Stephen's volume, the document has been copied into various publications in Mexico, Yucatan and Europe. The other attempt at an independent translation was that of the Abbé Brasseur (de Bourbourg), published at Paris in 1864, in the same volume with Landa's _Relacion de las Cosas de Yucatan_. The text he took from Stephens' book, errors and omissions included, and his translation is entirely based on the English one, as he evidently did not have access to the original Spanish of Pio Perez.
