The Incas' Sky

This book introduces readers to the astonishing civilisation of the Incas. Its novelty lies in its general but highly informative synthesis of their history and astronomy through the accounts of contemporary chronicles and recent archaeological findings. Richly illustrated with the author's own photographs, it will attract the attention of seasoned travellers interested in ancient civilisations and keen to discover what people were capable of achieving so long ago, but also any reader interested in the history and prehistory of South American peoples, including students or university researchers wanting to know more about the pre-Columbian civilizations of Peru. The Inca civilisation was in fact the culmination of cultural contributions from a dozen or so complex pre-Columbian civilizations, such as those of Chavìn, Nazca, Wari, or Tiwanaku. Intensely spiritual, the Inca people attributed metaphysical powers to all manner of objects and places they considered sacred, but at the same time the numerous alignments in their buildings show that they result from careful observations of the Sun, the Moon, and the stars at different times of the year. Indeed, the Incas were an essentially agrarian people, so time measurement and calendar devices were essential for the purely pragmatic problem of planning agricultural tasks during the tropical year. The book sets out to describe the Incas in their historical and geographical context, avoiding specialization or excessive technicality, but retaining a certain scientific rigor, and including a detailed consideration of their interest in the sky and astronomy.
