Beyond its architecture, urban planning and art, there is an aspect of the Mayan civilization that fascinates archaeologists: its decline. Over time, historians have understood that the decline was not sudden nor did it respond to a single factor, rather there was a sum that included changes in trade routes, wars and, above all, adverse weather, with droughts. severe and prolonged.
Now we know something more. Even during the stages of Classic Terminal (800-1000 AD) and Postclassic (1000-1500 AD), while large urban centers succumbed, there were settlements that adapted to climate changes.
What has happened? Which a group of archaeologists has just published an article in which they capture their years of research in a Mayan settlement located in ‘Birds of Paradise’, some wetlands located in the north of Belize. The site itself is not new. Scientists identified it long ago a few years with the help of lidara tool that is revolutionizing archaeology. What is new are the conclusions that its analysis has left.
He study is published in the magazine PNAS (Proceedings of the National Academy of Science) and, among other issues, concludes that the wetland offers valuable information about how the Mayans responded to the social and environmental changes they dealt with during two crucial stages of their history: the Classic Terminal and Postclassic, a period that goes from the 9th to the 16th centuries.
What have they found out? As they explain from New York University (NYU), to which the main author of the study belongs, one of the most interesting readings that the site leaves is the extent to which the Mayans adapted to the vagaries of the climate. Basically, researchers have proven that at a time when large urban centers were abandoned, pressured in part by intense droughtsthere were Mayan settlements that managed to survive in the wetlands. As? For its ability to adapt to the environment.
And how did they do it? Taking advantage of the means they had at hand. “Wetlands provided resources for hunting and fishing to ancient populations, in addition to serving as refuge in periods of drought and social upheavals,” they explain from NYU. The environment supplied them with something else, equally or even more valuable for their settlements: construction materials.
The site in question that they have analyzed in Belize in fact includes eight mounds of earth that could have served as a base for building buildings and a large elevated limestone platform. The experts also rescued wooden posts, animal remains and ceramic artifacts, clues that tell us about how life continued while other nearby urban centers declined.
What do the experts say? “Together these findings reveal a highly adaptable community with diverse tools, food and construction materials. It shows us that Mayan communities could change habitats and survive extreme climates,” explains Timothy Beachprofessor at the University of Texas at Austin, who nevertheless recognizes that “we still do not know the size of this wetland population and its functioning.”
Now archaeologists aim to go one step further. “Our next moves include expanding the excavations to understand how the Mayans built with unconventional wood, how they ate, and how this settlement fit into a region that was suffering from widespread abandonment.”
Why is it important? Because of the historical era we are talking about. In their article, the researchers assure that the Belize site demonstrates the ability of the ancient Mayans to adapt to “the profound challenges” that they had to live through from the 9th century AD. For reference, a team led by the University of Cambridge discovered not long ago that between 871 and 1021 they happened eight persistent droughtsof at least three years, in the Yucatán Peninsula. The worst of all actually lasted more than a decade.
The scientists arrived at that conclusion after analyzing a stalagmite from a Yucatan cave. And, beyond how spectacular it may be, the data is interesting because it tells us about the challenges that the Mayans faced during the Terminal Classic (800-1000 AD), when the limestone cities of the south they were abandonedthe dynasties declined and civilization moved north, losing part of its political and economic power in the area.
Are there more conclusions? “As the large urban centers of the Mayan regions succumbed to interconnected socio-environmental factors, the communities of the Birds of Paradise complex persisted through that transition by constructing a series of elevated structures of earth, stone and wood with direct access to the abundant resources and connectivity offered by the riparian wetland system,” reads the article published in PNAS.
“It provides evidence for persistent populations between the Elevated Interior Region and coastal regions during the Terminal Classic to Postclassic. While nearby highland urban centers were abandoned, this population continued to emphasize wetland agriculture and provides our best evidence for other subsistence strategies, such as fishing and gathering other proteins, reflected in the faunal assemblage,” they add the researchers.
What did they dig? That is another of the surprises that the study leaves behind. Archaeologists discovered what NYU describes as “the largest collection of architectural wood” located inland, as well as artifacts that help historians understand everyday life in the wetlands.
It may seem like a minor issue, but it is not common to find remains of wood in Mayan sites. On the contrary. Their very nature causes them to degrade in tropical environments. In Belize, experts have discovered “a unique opportunity” which allows them to better understand how the ancient Mayans built, what types of wood they used and how they used each one.
Is it so uncommon? The majority of preserved Mayan wooden remains are figurines, spears and boxes that were recovered mainly in caves in Belize at the beginning of the 20th century. Remains have also been found in mountainous and saline areas in the south of the country. The new findings go further.
“It challenges long-held beliefs that sites like this could not survive in the American tropics and suggests we might be overlooking similar sites,” admits Lara Sánchez-Morales, professor of anthropology at New York University. “It reminds us that the archaeological record of these environments is richer than we thought and encourages us to rethink how we search for and interpret settlements in the American tropics.”
