The changing ‘nature’ of Tiwanaku religion and the rise of an Andean state.

The means by which past complex societies thrived at high altitudes remain puzzling. In this paper I suggest that religious ideology and ritual practice shaped the cultural processes that fostered Tiwanaku state rise in the south-central Andean highlands. Physical changes in the monumental core of the state's principal centre are particularly revealing. Material transformations in monumental axiality, spatiality, materiality and iconography were critical elements in a changing religion that sought to integrate the symbolism of prominent generative forces such as mountains, vital elements such as water and recurring celestial cycles. After ad 500, Tiwanaku's innovative religion meshed imposing natural features with timeless solar cycles. This embodiment and objectification of nature was increasingly critical for a polity that thrived precariously on an effective coordination of fishing, herding and new technologies of high-altitude farming. The symbolic appropriation of the natural world and its immanent spiritual forces was constitutive of Tiwanaku's political integration of diverse societies and productive landscapes.
