Royal retainers may have been sent from all over to inhabit the lofty Inca site.
A new analysis of human remains buried at Machu Picchu reinforces the idea that royal retainers from all over the Inca empire were the permanent inhabitants of the famous Peruvian site.
High in Peru’s Andes, the skeletons of people buried at the famous Inca site of Machu Picchu tell a tale of displacement and devoted service. A new chemical analysis of these bones supports the previously postulated idea that Inca kings used members of a special class of royal retainers from disparate parts of the empire to maintain and operate the site, which served as a royal estate.
Dramatic differences in the remains’ ratios of certain chemical isotopes that collect in bone indicate that Machu Picchu’s permanent residents spent their early lives in varied regions east or southeast of the site, say anthropologist Bethany Turner of Georgia State University in Atlanta and her colleagues. Some Machu Picchu inhabitants had emigrated from spots along the central South American coast, while others hailed from valleys high in the Andes.
Inca royalty, who regularly visited the site, were not buried at Machu Picchu. They were buried at nearby Cuzco, the capital of the empire.
In an upcoming Journal of Archaeological Science, Turner’s team says that widely distributed geographic origins for Machu Picchu’s population fit with the notion that retainers, known as yanacona, were sent to the royal estate from all corners of the realm.
“This would have made for an interesting dynamic in the Machu Picchu population, as its members may have had little in common besides their service to the Inca elite,” Turner says. Immigrants brought a variety of customs, traditions and dialects to the site, in her view.
Yale University anthropologist Richard Burger says that the new study strengthens an argument he advanced in 2003. He hypothesized that Machu Picchu was run by royal retainers transferred from many parts of the Inca empire. He and his coworkers observed considerable variation in the ratio of certain carbon and nitrogen isotopes in 59 of 177 skeletons that had been excavated from three caves at Machu Picchu.
Turner’s group analyzed oxygen, strontium and lead isotopes in 74 of the skeletons. The researchers extracted isotopes from tooth enamel layers that develop during childhood. Wide variations in the isotopic composition of these substances suggest that individuals at Machu Picchu grew up in a variety of geological contexts with distinct water sources and available foods.
Isotopic variation among individuals at Machu Picchu argues against the possibility that they were drawn from a local peasant population or represented groups of servants dispatched to the site from one or two outside areas, Turner says. Locals would have shared an isotopic signature similar to that of local animals, whereas imported servants would have clustered into one or two isotopic categories.
