Leaders' ideological power was based on apparent access to deities and the supernatural. Evidence regarding Norte Chico religion is limited: an image of the Staff God, a leering figure with a hood and fangs, has been found on a gourd dated to 2250 BC. The Staff God is a major deity of later Andean cultures, and Winifred Creamer suggests the find points to worship of common symbols of gods. As with much other research at Norte Chico, the nature and significance of the find has been disputed by other researchers. The act of architectural construction and maintenance may also have been a spiritual or religious experience: a process of communal exaltation and ceremony. Shady has called Caral "the sacred city" ("la ciudad sagrada"): socio-economic and political focus was on the temples, which were periodically remodeled, with major burnt offerings associated with the remodeling.
