Early Civilizations in the Americas: Biographies and Primary Sources presents a collection of twenty-three biographies and primary sources---both text and photographs of artifacts---that provide detailed and focused views of the people of the early American civilizations, the artifacts they left behind, and the sources upon which the history of the early American civilizations are based. The volume is divided into three chapters: the Incas, the Mayas and their Ancestors, and the Aztec Empire. Each chapter is arranged loosely by topic and chronology. The biographies include Inca emperor Pachacutec, Maya king Pacal, and Aztec emperor Montezuma II. The primary sources feature artifacts such as the Inca quipu, or knotted counting cords, the Maya sacred calendar, and the Aztec Sun Stone. Also included are excerpts from the memoirs and histories compiled by indigenous writers and Spanish missionaries and conquerors in the decades following the conquest.
