El artículo trata de interpretar probables representaciones de fenómenos astronómicos, acaecidos durante la etapa terminal del Horizonte Medio (400-1100 d.C.), y su rol en los procesos y acontecimientos que venian sucediendo en el fenómeno arqueológico que denominamos Tiwanaku, a partir de la visión de la Astronomía Cultural.

This article tries to interpret probable representations of astrononomic phenomena, that happened during the last stage of Niddle Horizon (400-1100 A.D), and its role in the processes and events that may have been happening in the archaeological phenomena that we call Tiwanaku, from the vision of Cultural Astronomy. the method, which consists in crossing the archaeolotopographical variables with calculation and simulation virtual models for astronomic movement, will allow us an approach to a particular phenomenon: the sun's eclipse. We analyze that representations in the pottery recovered on the 2004 & 2005 fielswork of Chachapuma's Archaeological Project to contribute a little more to the interpretation of this discovery and the singular votive context where it belongs to.
