They’ve been explained as everything from final landing instructions for alien pilots to walking routes for religious pilgrims to eye candy for the gods of an ancient civilization.
But the mysterious Nasca Lines — hundreds of remarkably long and straight lines, plus an amazing assortment of huge and complex images, visible only from high above 200 square miles of Peruvian desert — aren’t what piqued Dr. Christina Conlee’s interest in Nasca.
“A lot of archaeology has started to concentrate not on the lines, but on the people who made them,” says Conlee, an associate professor in the Department of Anthropology at Texas State. “We’re working a lot on these issues, to get a better idea of the culture and how the lines fit into it.”
Her groundbreaking archaeological studies of the people of the Nasca — whose civilization lasted perhaps 1,000 years, beginning in 100 BC — were funded by the National Geographic Society, and they were the subject of a documentary on the National Geographic Channel and a feature in the magazine earlier this year.
The first modern men to see the figures were pilots flying over the region in the 1920s, and the first archaeologist to study them called them “great Incan ceremonial artifacts.” They have been explained as everything from messages to UFOs (in the 1968 best-seller, Chariots of the Gods) to guides for studying the skies to giant dowsing rods, pointing to underground water flows.
Conlee and many other archaeologists now believe the figures were part of a series of religious practices designed to ensure the continued flow of the life-giving water. Those practices also were part of what turned out to be Conlee’s groundbreaking contribution to the study of the Nasca people.
In 2004, Conlee unearthed a remarkably well-preserved skeleton in a region of the Nasca known as La Tiza. The headless body had been buried with a “head jar,” a piece of pottery decorated with images of a head and of plant life, indicating that the decapitation was indeed part of a fertility ritual.
“There were actually a couple of ‘aha’ moments,” Conlee says of her discovery. “The first came when we uncovered the jar and realized it was a head jar. This made me realize that this was likely a decapitated person, instead of someone whose head had been removed later, and that it was related to a ritual practice.”
The second came when the excavation team discovered evidence that the head indeed had been forcibly removed. And then came a third, thanks to a former classmate at Cal-Santa Barbara.
“Christina was excavating at La Tiza and found burials at places she didn’t expect,” said Dr. Michele Buzon, an assistant professor of anthropology at Purdue University. “She asked if I would join her as the project bioarchaeologist to study the human skeletal remains.”
Buzon, using a process called strontium isotope analysis, determined that the skeleton was of a young man from the local population. The revelation helped shed considerable light on the Nasca people’s rituals and helped further explain the lines and figures in the desert.
“We’re beginning to get a sense of the Nasca lines as places where people did rituals and made offerings to bring water,” Conlee says. “I think these so-called trophy heads are part of the same sort of religious and ritual practices.”
“Students like hearing first-hand accounts about people doing field work and seeing the images,” she says. “I think people have a lot of misconceptions of what archaeologists do — there’s that Indiana Jones idea. And there’s actually a little bit of that involved, and we do have some adventures. But a lot of it is sort of tedious and mundane work.
“Students really respond — somebody they see talking up there, their professor, and then what they do in the field, day-to-day stuff.”
Their curiosity this semester also extended to the making of the National Geographic Channel documentary, “Nasca Lines: The Buried Secrets,” which was spurred by discoveries made in the last 10 years about a civilization that disappeared 1,500 years ago.
“That was a whole new experience for me,” Conlee says of the video shoot, which took place during an actual excavation in Peru. The need to get the right shot for the video meant she sometimes had to do the same thing several times — picking up an artifact, holding it for the camera, making sure it was at the right angle. It was an enlightening experience, she says.
Not nearly as enlightening as the actual research, though.
“I didn’t go into graduate school to get a PhD and become Indiana Jones — I knew it wasn’t like that,” she says. “But there is that kind of puzzle to archaeology, that question, that mystery, that I think still kind of drives a lot of us into it. We want to find out more about putting these little pieces of the puzzle of the past together to figure out what they mean.”
