The text examines the pre-Toltec history of the native races of the Pacific states, with a primary focus on the early civilizations of Mexico and Central America. The narrative begins by analyzing the obscure origins of the American peoples, weighing the multitude of migration theories against the possibility of an autochthonous origin. It evaluates the reliability of traditional accounts, hieroglyphic records, and the works of Spanish chroniclers who sought to document the indigenous past.
Moving into specific historical traditions, the account details the Tzendal empire of Votan and the migration of the early Nahua nations. It explores the early settlements in Tamoanchan, the construction of the monumental pyramids of Teotihuacan, and the primitive societies that preceded the Toltec era, including the Olmecs and the legendary giants or Quinames. The narrative contrasts these northern developments with the rich mythological traditions of the Quiché nation preserved in the Popol Vuh, detailing the struggles against the mysterious powers of Xibalba and the ultimate triumph of the culture-heroes.
Throughout the text, the author addresses the difficulties in separating myth from history in native annals. By examining linguistic affinities, architectural monuments, and social institutions, the work attempts to establish a coherent chronology of the pre-Toltec epoch. The account concludes by synthesizing these diverse traditions into a comprehensive framework, acknowledging the persistent gaps in the early history of the American continent while rejecting unfounded speculations.
