Inca mummy. Mummified head and hand of an Inca mummy. Mummification is a process where tissues are preserved after death by extreme dessication in a dry climate. Parchment-like skin is seen covering the bones. Here, the hair is particularly well preserved. This mummy was 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.
