Inca mummy grave goods. Cotton bags found in mummy bundles. Mummy bundles are burials of bodies in the foetal position, wrapped up in a bundle containing essential items for the afterlife, and buried with other ceremonial offerings and grave goods. These cotton bags were from mummies excavated from Puruchuco-Huaquerones, a large Inca cemetery on the outskirts of Lima, Peru. The site has been excavated several times since 1999, with many well-preserved mummies being found. The Inca, a pre-Hispanic people from Peru, ruled an extensive empire in the Andean regions of northern South America in the 15th and 16th centuries.
