Archaeologists Find Remains of "High-Status" Women in Cahokia Burial Mound

Archaeologists in Illinois say a prominent pre-Columbia burial mound in the famous ancient city of Cahokia was hardly a monument to masculinity, as their predecessors in the 1960s had claimed. They published their findings in several journals, including American Antiquity.

A thousand years ago, the complex cities and suburbs of Mississippian peoples sprawled across the Midwest. Cahokia, the largest urban center, lay just across the river from modern-day St. Louis. At its peak in the 13th century, it rivaled London in size. Then, over time, like so many civilizations do, it vanished.

But the Mississippians were builders of mounds, whose works left large, hard-to-miss marks on the landscape. French and Spanish explorers first spotted Cahokia’s burial mounds in the 1500s, and we’ve been unearthing its secrets ever since.

Much of what we know today about Cahokia culture comes from the work of one man. Archaeologist Melvin Fowler was digging at the site in 1967 when he uncovered an enormous burial ground. The area known today as Mound 72 yielded five mass graves and dozens of scattered individual resting places, containing a total of 270 people who had been buried between 1000 CE and 1200 CE. But not all the dead had been treated equally. Two bodies in particular seemed to have been accorded special care. They were stacked, one atop the other, in a bed of beads, and surrounded by the painstakingly arranged bodies of four people who had died at the same time.

To Fowler, the beads between the bodies and those scattered by their heads appeared to form the shapes of birds. Fowler knew that birds were associated with warriors and supernatural powers in some Native American traditions, and so he concluded that the two central figures must have been legendary warrior chiefs. The bodies buried with them must have been servants, there to glorify their leaders’ manly feats.

Nobody corrected him. Over time, the theory that Cahokia was a hierarchical he-man culture became accepted fact. And it might have stayed that way, had modern archaeologists not decided to double-check Fowler’s findings. They took a closer look at their predecessors’ notes and maps, then continued to explore the site. They found more bodies right off the bat; the beaded burial, as it’s come to be known, contained 12 bodies, not 6. 

They took bone and tooth samples from the bodies and tested them to see if they could determine the approximate ages of the deceased. That’s when they realized that a lot of the bodies were not men at all. One of the so-called warrior men was a woman, and other stacked pairs nearby were male-female as well. The mass graves had plenty of women in them. Nearby, they even found the remains of a child.

Co-author Thomas Emerson is the director of the Illinois State Archaeological Survey. He says the inclusion of women in these high-status burial sites pretty much tosses Fowler’s male supremacist theory out the window.

"Now, we realize, we don't have a system in which males are these dominant figures and females are playing bit parts,” he said in a press statement. “And so, what we have at Cahokia is very much a nobility. It's not a male nobility. It's males and females, and their relationships are very important."

Emerson says including higher-class women in Mound 72 is consistent with other burial rituals in the area. All around Cahokia, he says, he found symbols of “life renewal, fertility, agriculture. Most of the stone figurines found there are female.”

Fowler and his contemporaries mistakenly assumed that there was one Native American culture rather than a variety of cultures, regardless of time or place. "People who saw the warrior symbolism in the beaded burial were actually looking at societies hundreds of years later in the southeast, where warrior symbolism dominated, and projecting it back to Cahokia and saying: 'Well, that's what this must be,'" Emerson said. "And we're saying: 'No, it's not.'"

10 Surprising Ways Senses Shape Perception
The American Museum of Natural History
The American Museum of Natural History

Every bit of information we know about the world we gathered with one of our five senses. But even with perfect pitch or 20/20 vision, our perceptions don’t always reflect an accurate picture of our surroundings. Our brain is constantly filling in gaps and taking shortcuts, which can result in some pretty wild illusions.

That’s the subject of “Our Senses: An Immersive Experience,” a new exhibition at the American Museum of Natural History in New York City. Mental Floss recently took a tour of the sensory funhouse to learn more about how the brain and the senses interact.

1. LIGHTING REVEALS HIDDEN IMAGES.

Under normal lighting, the walls of the first room of “Our Senses” look like abstract art. But when the lights change color, hidden illustrations are revealed. The three lights—blue, red, and green—used in the room activate the three cone cells in our eyes, and each color highlights a different set of animal illustrations, giving the viewers the impression of switching between three separate rooms while standing still.

2. CERTAIN SOUNDS TAKE PRIORITY ...

We can “hear” many different sounds at once, but we can only listen to a couple at a time. The AMNH exhibit demonstrates this with an audio collage of competing recordings. Our ears automatically pick out noises we’re conditioned to react to, like an ambulance siren or a baby’s cry. Other sounds, like individual voices and musical instruments, require more effort to detect.

3. ... AS DO CERTAIN IMAGES.

When looking at a painting, most people’s eyes are drawn to the same spots. The first things we look for in an image are human faces. So after staring at an artwork for five seconds, you may be able to say how many people are in it and what they look like, but would likely come up short when asked to list the inanimate object in the scene.

4. PAST IMAGES AFFECT PRESENT PERCEPTION.

Our senses often are more suggestible than we would like. Check out the video above. After seeing the first sequence of animal drawings, do you see a rat or a man’s face in the last image? The answer is likely a rat. Now watch the next round—after being shown pictures of faces, you might see a man’s face instead even though the final image hasn’t changed.

5. COLOR INFLUENCES TASTE ...

Every cooking show you’ve watched is right—presentation really is important. One look at something can dictate your expectations for how it should taste. Researchers have found that we perceive red food and drinks to taste sweeter and green food and drinks to taste less sweet regardless of chemical composition. Even the color of the cup we drink from can influence our perception of taste.

6. ... AND SO DOES SOUND

Sight isn’t the only sense that plays a part in how we taste. According to one study, listening to crunching noises while snacking on chips makes them taste fresher. Remember that trick before tossing out a bag of stale junk food.

7. BEING HYPER-FOCUSED HAS DRAWBACKS.

Have you ever been so focused on something that the world around you seemed to disappear? If you can’t recall the feeling, watch the video above. The instructions say to keep track of every time a ball is passed. If you’re totally absorbed, you may not notice anything peculiar, but watch it a second time without paying attention to anything in particular and you’ll see a person in a gorilla suit walk into the middle of the screen. The phenomenon that allows us to tune out big details like this is called selective attention. If you devote all your mental energy to one task, your brain puts up blinders that block out irrelevant information without you realizing it.

8. THINGS GET WEIRD WHEN SENSES CONTRADICT EACH OTHER.

The most mind-bending room in the "Our Senses" exhibit is practically empty. The illusion comes from the black grid pattern painted onto the white wall in such a way that straight planes appear to curve. The shapes tell our eyes we’re walking on uneven ground while our inner ear tells us the floor is stable. It’s like getting seasick in reverse: This conflicting sensory information can make us feel dizzy and even nauseous.

9. WE SEE SHADOWS THAT AREN’T THERE.

If our brains didn’t know how to adjust for lighting, we’d see every shadow as part of the object it falls on. But we can recognize that the half of a street that’s covered in shade isn’t actually darker in color than the half that sits in the sun. It’s a pretty useful adaptation—except when it’s hijacked for optical illusions. Look at the image above: The squares marked A and B are actually the same shade of gray. Because the pillar appears to cast a shadow over square B, our brain assumes it’s really lighter in color than what we’re shown.

10. WE SEE FACES EVERYWHERE.

The human brain is really good at recognizing human faces—so good it can make us see things that aren’t there. This is apparent in the Einstein hollow head illusion. When looking at the mold of Albert Einstein’s face straight on, the features appear to pop out rather than sink in. Our brain knows we’re looking at something similar to a human face, and it knows what human faces are shaped like, so it automatically corrects the image that it’s given.

More Details Emerge About 'Oumuamua, Earth's First-Recorded Interstellar Visitor
 NASA/JPL-Caltech
NASA/JPL-Caltech

In October, scientists using the University of Hawaii's Pan-STARRS 1 telescope sighted something extraordinary: Earth's first confirmed interstellar visitor. Originally called A/2017 U1, the once-mysterious object has a new name—'Oumuamua, according to Scientific American—and researchers continue to learn more about its physical properties. Now, a team from the University of Hawaii's Institute of Astronomy has published a detailed report of what they know so far in Nature.

Fittingly, "'Oumuamua" is Hawaiian for "a messenger from afar arriving first." 'Oumuamua's astronomical designation is 1I/2017 U1. The "I" in 1I/2017 stands for "interstellar." Until now, objects similar to 'Oumuamua were always given "C" and "A" names, which stand for either comet or asteroid. New observations have researchers concluding that 'Oumuamua is unusual for more than its far-flung origins.

It's a cigar-shaped object 10 times longer than it is wide, stretching to a half-mile long. It's also reddish in color, and is similar in some ways to some asteroids in our solar system, the BBC reports. But it's much faster, zipping through our system, and has a totally different orbit from any of those objects.

After initial indecision about whether the object was a comet or an asteroid, the researchers now believe it's an asteroid. Long ago, it might have hurtled from an unknown star system into our own.

'Oumuamua may provide astronomers with new insights into how stars and planets form. The 750,000 asteroids we know of are leftovers from the formation of our solar system, trapped by the Sun's gravity. But what if, billions of years ago, other objects escaped? 'Oumuamua shows us that it's possible; perhaps there are bits and pieces from the early years of our solar system currently visiting other stars.

The researchers say it's surprising that 'Oumuamua is an asteroid instead of a comet, given that in the Oort Cloud—an icy bubble of debris thought to surround our solar system—comets are predicted to outnumber asteroids 200 to 1 and perhaps even as high as 10,000 to 1. If our own solar system is any indication, it's more likely that a comet would take off before an asteroid would.

So where did 'Oumuamua come from? That's still unknown. It's possible it could've been bumped into our realm by a close encounter with a planet—either a smaller, nearby one, or a larger, farther one. If that's the case, the planet remains to be discovered. They believe it's more likely that 'Oumuamua was ejected from a young stellar system, location unknown. And yet, they write, "the possibility that 'Oumuamua has been orbiting the galaxy for billions of years cannot be ruled out."

As for where it's headed, The Atlantic's Marina Koren notes, "It will pass the orbit of Jupiter next May, then Neptune in 2022, and Pluto in 2024. By 2025, it will coast beyond the outer edge of the Kuiper Belt, a field of icy and rocky objects."

Last month, University of Wisconsin–Madison astronomer Ralf Kotulla and scientists from UCLA and the National Optical Astronomy Observatory (NOAO) used the WIYN Telescope on Kitt Peak, Arizona, to take some of the first pictures of 'Oumuamua. You can check them out below.

Images of an interloper from beyond the solar system — an asteroid or a comet — were captured on Oct. 27 by the 3.5-meter WIYN Telescope on Kitt Peak, Ariz.
