This study presents new information on the ceramic styles of the Cuzco region during the Early Intermediate period and the Middle Horizon. The results of excavations in 1999 and 2000 at three sites in the Cuzco Valley afford better definition of the ceramic styles and dating of these two time periods. New information is presented on the Wari occupation of the Cuzco region and the influence that Altiplano (i.e., Lake Titicaca) cultures had on the Cuzco region during these time periods.
