The first Maya dictionary printed was issued in the City of Mexico in 1571. It was published as that of Father Luis de Villalpando, but as he had then been dead nearly twenty years, it was probably merely based upon his vocabulary. It was in large 4to, of the same size as the second edition of Molina's _Vocabulario de la Lengua Mexicana_. At least one copy of it is known to be in existence. For more than three centuries no other dictionary was put to press, although for some unexplained reason that of Villalpando was unknown in Yucatan. At length, in 1877, the publication was completed at Mérida, of the _Diccionario de la Lengua Maya_, by Don Juan Pio Perez.[75-1] It contains about 20,000 words, and is Maya-Spanish only. It is the result of a conscientious and lifelong study of the language, and a work of great merit. The deficiencies it presents are, that it does not give the principal parts of the verbs, that it omits or does not explain correctly many old terms in the language, and that it gives very few examples of idioms or phrases showing the uses of words and the construction of sentences. I can say little in praise of the _Vocabulaire Maya-Francais-Espagnole_, compiled by the Abbé Brasseur (de Bourbourg), and printed in the second volume of the Report of the _Mission Scientifique au Mexique et à l'Amerique Centrale_. It contains about ten thousand words, but many of these are drawn from doubtful sources, and are incorrectly given; while the derivations and analogies proposed are of a character unknown to the science of language. Besides the above and various vocabularies of minor interest, I have made use of three manuscript dictionaries of the first importance, which were obtained by the late Dr. Berendt. They belonged to three Franciscan convents which formerly existed in Yucatan, and as they are all anonymous, I shall follow Dr. Berendt's example, and refer to them by the names of the convents to which they belonged. These were the convent of San Francisco in Merida, that at the town of Ticul and that at Motul. The most recent of these is that of the convent of Ticul. It bears the date 1690, and is in two parts, Spanish-Maya and Maya-Spanish. The _Diccionario del Convento de San Francisco de Merida_ bears no date, but in the opinion of the most competent scholars who have examined it, among them Señor Pio Perez, it is older than that of Ticul, probably by half a century. It is also in two parts, which have evidently been prepared, by different hands.
