A series of essays compiles archaeological, ethnological, mythological, graphic, and linguistic research on the indigenous cultures of the American continent. The essays review legendary, monumental, industrial, linguistic, physical, and geologic evidence to reassess theories of antiquity and migration, arguing for indigenous development and continuity. Topics include prehistoric stone industries and glacial contexts, the question of mound-building peoples, critical readings of Toltec traditions, analyses of Quiche sacred names and Popol Vuh material, and examinations of native graphic systems and poetic expression. Methodological reflections emphasize psychological as well as physical dimensions of early societies.
