History, Calendar and Skylore of the Incas at the Time of the Spanish Conquest

A significantly expanded translation of the author's Pachap vnancha: El calendario metropolitano del Estado Inca, this book is the culmination of several decades of research on Andean calendar-astronomical systems and their role in the ceremonial, economic and political aspects of the region's pre-Hispanic societies. This book presents a reconstruction of the state calendar used in Inca Tahuantinsuyu for purposes of programming, coordination and control of various social activities on an imperial scale. Although the correlation between Mesoamerican calendars and the Julian calendar has long been used to interpret events in that part of the world, this work is the first of its kind for the Andean region.
