Probable dates for events discussed in text, plotted against currently popular chronologies for Tiahuanaco and Huari. Dates are intended to represent calibrated years (but not Southern Hemisphere corrected). As stated in the chapter text, the date of cal. AD 500 seems too early for the onset of the Tiwanaku Period at Tiahuanaco; AD 650 to 700 seems more likely, at least for the radical changes in ceramics that brought in new vessel forms decorated with new polychrome design themes, as well as the appearance of SAIS-style stone sculptures.
