Thousands of Inca Mummies Raised From Their Graves

<< Back to Page 1   Page 2 of 2

Guerrilla activity in the mountains during the 1980s drove thousands of refugees to the relative sanctuary of Lima. Hundreds of families erected makeshift homes on top of the Inca burial ground at Puruchuco. They named the settlement Tupac Amaru, after the last Inca ruler, who was executed by Spanish conquerors in 1572.

Tupac Amaru came to symbolize the tension between the needs of living Peruvians attracted to Lima's security and economic opportunities, and their country's Inca heritage, including buried ruins, artifacts—and mummies. Puruchuco was a national archaeological monument; Tupac Amaru was the living space for the people of today, desperately in need of shelter, employment, and safety.

Over time it became clear that Tupac Amaru was not going to be a temporary settlement. Residents began pressing political representatives for title to the Puruchuco land so that they could build permanent dwellings and install utilities. They raised a considerable sum of money among themselves to help fund excavations so that the site could be examined professionally, then shut down permanently as an archaeological area.

It was during that archaeological exploration, in 1999 and 2000, that Cock and others discovered the extent of the treasures under Tupac Amaru. While some graves had been discovered, and even looted, no one had realized thousands more remained hidden. Or that some of the graves were of the Inca elite, containing priceless artifacts.

"We could not excavate under the houses, so we were confined to the streets and the school playground," Cock said. "What we found was so big—with so many mummies and artifacts—that we applied to National Geographic for emergency funding to take out as much as we could before the bulldozers closed in and it was all lost to us."

In ten weeks of excavations last year, Cock's team recovered more than 1,200 bundles of different types.

Residents Relieved

Cock's team employed Tupac Amaru residents to help with the digging and guarding of the excavations. Many of the townspeople were relieved to see the mummies removed, Cock said. "They are afraid of the dead; they believe they cause them daña [illnesses], which is why they would prefer it if the mummies are moved."

The mummies were entombed in ideal conditions for preservation—the extremely dry soil of the coastal Peruvian desert, where no rain may fall for as long as 20 years. "Preservation conditions are so good, we can determine the sex of people simply by looking at their genitals," said Cock. "Even the eyes are still there."

After being well preserved for centuries, the mummies have been deteriorating rapidly as a result of disturbance from human occupation. Residents of Tupac Amaru have scraped the surface of the ground to build makeshift dwellings, ripping up mummies in the process. Because the settlement has no sewerage, residents dump water and wastes in the dirt streets. Some of the mummies have decomposed as a result of the seepage.

Archaeologists are particularly intrigued by the wide variety of mummies that have been excavated from the site.

"There is some evidence of a large Inca palace existing near the cemetery," Cock said. "It appears that a lot of the Inca elite were buried here, together with the common people who would have lived in the nearby hills. We believe we may have bodies from ten different social stratifications here."

The range of status, age, and gender of the mummies—as well as the rich textiles and other artifacts recovered—are expected to give archaeologists major insight into Inca culture and the people themselves. The well-preserved bodies will enable scientists to determine the general health of the population, genetic relationships, sources of food, and causes of death.

The find, taken as a whole, will also shed light on the Inca political, social, and economic systems.

"We are so happy we have this, and not the grave robbers," Cock said. Looting and smuggling of antiquities is a major problem in Peru and many other countries, and many sites have been stripped of their contents before archaeologists have had an opportunity to study the remains. Mummies dug up by robbers have often been found strewn on open ground, denuded of ornamentation and clothing.

Before Cock's excavations, Tupac Amaru residents who encountered a mummy often would douse it with gasoline and burn it.

"The people of Tupac Amaru were very supportive of this project. They helped pay for it, and helped with the excavation and guarding of the open graves," Cock said.

It will take scientists years to unwrap and study the contents of the Puruchuco mummy bundles. The work is done with tenderness, in part out of deep respect for the dead.

"We do treat and deal with them not only as people but as ancestors, from whom we all relate in one or another way," Cock said. "These people are us from a few hundred years ago."

Cock estimates that some 60 percent of the occupants of the Inca burial ground have not been recovered.

After the scientists have finished studying the recovered mummies and artifacts, they will be returned to the Puruchuco area for display in a museum.
