While installing new gas lines just beneath the busy streets of Lima, Peru, utility workers unearthed an unexpected archaeological bounty: eight pre-Inca mummies and a wealth of artifacts.
The mummies, which were buried in a seated position, were wrapped in funeral bales made of cotton cloth and tied with ropes braided from liana, a woody vine that grows in rainforests. Archaeologists think the mummies were part of a pre-Inca culture known as the Ichma (also spelled Ychma) that incorporated into the Inca Empire in the 15th century, according to the Associated Press.
"We are recovering those [remains] of the lost history of Lima hidden under the tracks and streets," Jesus Bahamonde, an archaeologist at Cálidda, a local natural gas company that was leading the utility project, told the Associated Press.
In addition to the funeral bales, which archaeologists think contain two adults and six children, workers discovered more recent artifacts, such as opium pipes, hand-rolled cigarettes, shoes, Chinese playing cards, a Peruvian silver coin minted in 1898 and a contract written in Spanish in 1875.
"When the Spaniards arrived in the 16th century, they found an entire population living in the three valleys that today occupy Lima," Bahamonde told the Associated Press. "What we have is a kind of historical continuation."
This isn't the first time that a construction project has revealed parts of Lima's past. In his time at Cálidda, Bahamonde said, more than 1,900 archaeological finds have been unearthed in the urban region, including mummies, pottery and textiles.
Lima is known for its abundance of archaeological sites, including 400 "huacas," or burial mounds, scattered throughout the city, according to The Washington Post.
