The library of the "Museo Nacional" of the City of Guatemala, contains a number of fragments of a "_Historia de la Provincia de San Vicente Ferrer de Chiapas y Guatemala_," the third book of which is superscribed: "Isagoge histórico apologético general de todas las Indias."--There is no date nor name of author, but it can be conjectured that it was written in the 16th century.--Gregorio García also quotes: _Fray Estévan de Salazar_. "Discurs. Symb. apost." who in turn is said to refer to a book entitled "_Historia, i Relacion de la Teología de los Indios Mexicanos_," said book being lost in a shipwreck, 1564. _Writers of the Seventeenth Century._ GREGORIO GARCIA. ANTONIO DE HERRERA. JUAN DE TORQUEMADA. ANTONIO DE REMESAL. AUGUSTIN DE VETANCOURT. GIL GONZALEZ DÁVILA. JUAN DIAZ DE LA CALLE. AUGUSTIN DÁVILA-PADILLA. "Historia de la Fundacion y Discurso de la Provincia de Santiago de México." 1st edition, Madrid, 1596; 2d edition, Brussels, 1625.--Mentions Chiapas only in connection with the biography of Las Casas.--The first edition has almost disappeared, so that it is practically a book of the 17th century. AUGUSTIN CANO. "Historia de la Provincia de Predicadores de San-Vicente de Chiapas y Guatemala."--Fragment of a MS. at the "Museo Nacional" of Guatemala. * * * * * The following books are known to have existed once: FRAY JUAN ZAPATA Y SANDOVAL. "Cartas al Conde de Gomera ... sobre los Indios de Chiapas." "Cartas al Rey sobre el Estado Dulce Diócesis de Chiapas." * * * * * I make no mention of the compilations and general collections containing references to Chiapas. They are not numerous.--Gregorio García in his book, "Origen de los Indios," has probably the earliest mention of the ruins of Ocosingo, and even perhaps, some indication about those of Palenque.--Cortez who, accompanied by Bernal Diez, passed very near Palenque in 1525, did not take any notice of the pueblo,--which at that time was certainly not inhabited. _Writers of the Eighteenth Century._ NUÑEZ DE LA VEGA. "Constituciones diocesanas del Obispado de Chiapas." Rome, 1702. Important for its reports on the idolatrous rites and the traditions of the aborigines. LORENZO BOTURINI BERNADUCCI. "Idea de una Nueva Historia General de la America Septentrional." Madrid, 1746. Valuable for his mention of the Calendar of Chiapas. MARIANO FERNANDEZ DE VEYTIA Y ECHEVERRIA. "Historia del Origen de las gentes que poblaron la America Septentrional que llaman la Nueva-España, con noticia de los primeros que establecieron la monarquía que en ella floreció de la nacion Tolteca."--This work has been published as lately as 1836, at Mexico, by C. F. Ortega, under the title of "Historia antigua de México."--It contains notices of the calendar of Chiapas. F. X. CLAVIGERO. S. J. (ABBATE.) ANTONIO DE ALCEDO. JOSEPH ANTONIO DE VILLA-SEÑOR Y SANCHEZ.
