The first two books in this series dealt with the Aztec and Mayan cultures. To complete the trilogy, Mr. von Hagen has now written an informative extremely readable account of the incas. In which he recaptures the cultural ideas, every-day line, economic organization, historical , language and religion of that glorious ancient civilization. Alberto Beltran's line drawings help visualize the interior of Inca homes, the combination market fair and festival known as the catu, the royal hunt, and perceptive explanations point up the importance of the Sun God and the great Inca rulers. In reorganizing the tenets and life-style of an extinct culture, Mr. von Hagen breathes new life into what many regard as a hopeless gap in the maze of pre-history. Since the high school curriculum generally presents the incas as seen by their Spanish conquerors, this should provide a better rounded picture.
