Pedro de Cieza de León embarked from Spain at fourteen years old to seek his fortune in the New World, ultimately spending seventeen years participating in military expeditions and documenting the territories of South America. His chronicle, representing the first part of a grand historical design, systematically details the geography, ports, rivers, and provinces encountered along a twelve-hundred-league route from Panama through the valleys of the Cauca, past Popayan, and down to the silver mines of Potosi. Cieza de León meticulously records the latitudes of coastal anchorages, the infrastructure of the Inca empire including its famous roads and aqueducts, and the varied topography ranging from desert coastlines to frozen Andean plateaus and dense tropical forests. Alongside his geographical surveys, the author portrays the diverse indigenous populations, detailing their languages, architectural achievements in stone, agricultural techniques, and religious ceremonies, while frequently noting their pervasive practice of ritual cannibalism and warfare.
While heavily influenced by the religious dogmas of his time which viewed indigenous spiritual practices as demonic, Cieza de León maintains an exceptional standard of observational accuracy and fairness in evaluating the cultures he encountered. He laments the widespread destruction, famine, and population collapse wrought by the Spanish conquest, contrasting the brutal excesses of undisciplined soldiers with the enlightened governance once maintained by the Inca kings. The narrative stands as an invaluable primary source for historians, preserving precise ethnographic and geographical details that would otherwise have been lost to time.
