Local oral history suggests the jars are probably massive, ancient burial urns.
Hundreds of huge stone jars lie partially buried on hillsides and ridges in northeastern India. A recent survey found 65 jars at four previously undocumented sites, and the survey’s leaders say there are probably many more sites still hidden in the area’s mountainous forests. The jars are part of a whole landscape of megaliths carved by an ancient Indian culture which—so far—archaeologists know little about.
Enormous burial urns
Sometimes in India’s ancient past, people carved giant jars, some up to two meters wide and three meters tall, from solid sandstone blocks. They transported the jars to hillsides and ridges and lined them up carefully, with a good view of the lowlands. Today, hundreds of those jars are in various states of disrepair, spread across a 300 square kilometer swath of Assam, a state in northeast India.
Archaeologists say the jars are probably massive burial urns, but almost nothing is known about the people who made them. It’s not even clear exactly how old the jars are, because the types of dating that could provide that information haven’t been done yet. “We still don’t know who made the giant jars or where they lived,” said Australian National University archaeologist Nicholas Skopal, a co-author of the recent paper, in a statement. “It seems as though there aren’t any living ethnic groups in India associated with the jars.”
The Naga people who lived in the area in the 1930s told a visiting anthropologist about a “lost people” they called the Siemi, who had made jars to hold the remains of their dead. Apparently the Siemi buried their dead with beads and iron objects; the Naga reported that their ancestors used to search the jars for those objects. In the process, they also found cremated human remains.
Archaeologists, led by Tilok Thakuria of North Eastern Hill University and Uttam Bathari of Gauhati University, recently surveyed two areas of dense tropical forest in Assam. They found four jar sites that had lain forgotten since their unknown makers left them behind (or since the ancestral Naga last looted them). That brings the number of jar sites in India to 11, with nearly 800 jars among them. And Thakuria, Bathari, and their colleagues say more are probably waiting to be rediscovered.
When in doubt, it’s probably ceremonial
As enigmatic as the jars themselves are, they’re just one part of a whole landscape of carved stone that archaeologists don’t yet fully understand. Thakuria, Bathari, and their colleagues say it shows “startling complexity and wide distribution.”
Some of Assam’s megaliths are flat circles of stone, about 70 cm to 80 cm wide and carved with human figures and geometric shapes. Archaeologists surveying the sites since 2014 have found these carved discs arranged in “lattice formations,” usually a few hundred meters away from a cluster of jars. And alongside many of the jars lie rectangular stone slabs, about a meter long and half that wide, with curved tops and human figures carved into their fronts.
Archaeologists still aren’t sure exactly what significance the carved sandstone discs and slabs once held for the people who crafted them and transported them to the hillsides of Assam. There’s a running joke among archaeologists that if you can’t figure out what an object was for, it’s probably something ceremonial. But in this case, it’s no joke—Thakuria, Bathari, and their colleagues suggest “some ritual connection between all three features” since they’re arranged so close together and in such consistent ways.
But the different types of carved stones—discs, slabs, and jars—may have been crafted and installed in different phases as the sites grew, similar to the thousands of years of change and growth that produced Stonehenge in the UK. A type of dating called optically stimulated luminescence, which measures how long it’s been since a chunk of stone was exposed to sunlight, could help reconstruct a timeline for Assam’s megaliths.
Civilization lost and found
The Naga oral history suggests connections with another site, roughly 1,000 kilometers away. The giant stone jars of Assam are strikingly similar to the thousands clustered on the Plain of Jars in Laos, which date to the late 1000s BCE. In Laos, the jars are definitely funeral urns on a megalithic scale; human bones have been found inside the jars and buried in the soil around them. And archaeologists have suggested a similar role for other large stone jars found in Indonesia.
Thakuria, Bathari, and their colleagues say there may be cultural links between the jar-makers of Laos, India, and Indonesia. Still, to be sure, they’ll need to do more research, such as comparing the jars and their carved decorations in all three countries.
For the moment, however, the newly rediscovered jar sites are part of a landscape of unanswered-but-probably-answerable questions. All we know about the culture that carved the jars and the other megaliths is that the Naga called them the Siemi, they buried their dead in stone jars, and they may have had some cultural connection with different groups of people in Laos and Indonesia.
Your faithful correspondent doesn’t toss around words like “lost civilization” lightly, but this might come close to qualifying.
But everything is a mystery until you find more evidence and solve it. More excavations, especially at settlements like the one Indian archaeologists found near a jar site in 2014, and more study of the artifacts we’ve found so far could shed a lot of light on who the jar-makers were, how they lived, and what happened to them.
The past in peril
Initially, most of the jars at sites like Loungmailai stood upright, with just their conical bases buried in the ground for stability. Today, most of the jars are broken, damaged by centuries or millennia of forest growth, construction, and road-cutting. Seventy-one of the 92 jars along the sloping ridgeline at Loungmailai are broken, primarily due to forest growth and generations of fires set to clear farmland. And elsewhere, most are either broken, buried, fallen over, or some combination of the three.
That gives archaeologists a sense of urgency for finding and documenting the jars.
“The longer we take to find them, the greater chance that they will be destroyed, as more crops are planted in these areas and the forests are cut down,” said Skopal.
