Lewis Spence's The Mythologies of Ancient Mexico and Peru places the religions of the ancient Americas beside the great faiths of Egypt, Greece, Islam, and Buddhism, arguing that they deserve equal scholarly attention. Drawing on myth, archaeology, and comparative religion, the book asks where these civilizations came from and how their beliefs took shape. It suggests that the peoples of Mexico and Peru were of mixed ancient origin, that their mythologies were largely indigenous, and that buried cities and long-lost cultures in Mesoamerica and the Andes helped form the religious traditions inherited by the Aztecs and Incas. From there, the study moves into the sacred worlds of both civilizations. It examines Mexican religion with special attention to the priesthood, ritual, and the power of ceremony in daily life, then turns to Inca worship, where sun reverence, sacrifice, and public observance bound state and faith together. Throughout, the book presents ancient Mexican and Peruvian religion as rich, disciplined, and deeply revealing of the spiritual life of the pre-Columbian Americas.
