The various works which contain notices of the "Popol Vuh" and the kindred questions of Mayan and Kiché mythology are so difficult of access to the majority of readers that it has been thought best to divide them into two classes: (1) those which can be more or less readily purchased, and which are, naturally, of more recent origin; and (2) those which are not easy to come by, and which, generally speaking, are the work of Spanish priests and colonists of the sixteenth, seventeenth, and eighteenth centuries. I The work on the subject which is most easily obtained, and indeed the only work which gives the original Kiché text, is that of the Abbé Brasseur de Bourbourg, "Vuh Popol: Le livre sacré de Quichés et les mythes de l'antiquité Américaine." The Kiché text was translated by the assistance of natives into French, and the translation is more or less inaccurate. The notes and introduction must be read by the student with the greatest caution. It was published at Paris in 1861. Ximenes' translation into Spanish of the "Popol Vuh" and that of Gavarrete are about of equal value, rather inaccurate, and accompanied by scanty notes. The title of the first is "Las Historias del Origin de los Indios de Guatemala, par el R. P. F. Francisco Ximenes (Vienna, 1856), and of the second, "El Popol Vuh," (San Salvador 1905). This exhausts the list of works written exclusively concerning the "Popol Vuh." The other works of Brasseur and those of Brinton contain more or less numerous allusions to it, but references to it in standard works of mythology are exceedingly rare. The only other works which have a bearing upon the subject are those upon Mayan and Kiché mythology, or which, among other matter, historical or political, refer to it in any way. The most important of these are: Dr. Otto Stoll--"Ethnographie der Republik Guatemala." ---- "Ethnologie der Indianerstämme von Guatemala." Scherzer--"Die Indianer von Santa Catalina Istlavacan." Müller--"Geschichte der Amerikanischen Urreligion" (1855). E. Förstemann--"Commentary on the Maya Manuscript," in the Royal Public Library of Dresden. Translation from the German by S. Wesselhoeft and A. M. Parker (Harvard University, 1906). E. Seler--"Über den Ursprung der mittelamerikanischen Kulturen" (1902). ---- "Ein Wintersemester in Mexico und Yucatan" (1903). ---- "Codex Fejerváry-Mayer" (Berlin, 1901). P. Schellhas--"Representation of Deities of the Maya Manuscripts," translated by S. Wesselhoeft and A. M. Parker (Cambridge, Mass., 1904). Cyrus Thomas--"The Maya Year," Washington, 1894. ---- "Notes on Maya and Mexican Manuscripts." W. Fewkes--"The God 'D' in the Codex Cortesianus," (Washington, 1895).
