The "old writings" to which the Prebend alludes were composed by natives who had learned to write the Maya in the alphabet adopted by the early missionaries and conquerors. An official document in Maya, still extant, dates from 1542, and from that time on there were natives who wrote their tongue with fluency. But their favorite compositions were works similar to those to which their forefathers had been partial, prophecies, chronicles and medical treatises.

Relying on their memories, and no doubt aided by some of the ancient hieroglyphical manuscripts, carefully secreted from the vandalism of the monks, they wrote out what they could recollect of their national literature.

There were at one time a large number of these records. They are referred to by Cogolludo, Sanchez Aguilar and other early historians. Probably nearly every village had one, which in time became to be regarded with superstitious veneration.

Wherever written, each of these books bore the same name; it was always referred to as "The Book of Chilan Balam." To distinguish them apart, the name of the village where one was composed was added. Thus we have still preserved to us, in whole or in fragments, the Book of Chilan Balam of Chumayel, of Kaua, of Nabula, etc., in all, it is said, about sixteen.

"Chilan Balam" was the designation of a class of priests. "Chilan," says Bishop Landa, "was the name of their priests, whose duty it was to teach the sciences, to appoint holy days, to treat the sick, to offer sacrifices, and especially to utter the oracles of the gods. They were so highly honored by the people that usually they were carried on litters on the shoulders of the devotees."[69-1] Strictly speaking, in Maya, _chilan_ means "interpreter," "mouth-piece," from "_chij_," "the mouth," and in this ordinary sense frequently occurs in other writings. The word _balam_--literally, "tiger,"--was also applied to a class of priests, and is still in use among the natives of Yucatan as the designation of the protective spirits of fields and towns, as I have shown at length in a study of the word as it occurs in the native myths of Guatemala.[70-1] "_Chilan Balam_," therefore, is not a proper name, but a title, and in ancient times designated the priest who announced the will of the gods and explained the sacred oracles. This accounts for the universality of the name and the sacredness of its associations.
