When diplomacy fails: After gifts, Teotihuacan turned on Maya cities

The monkey is the oldest known captive, exported primate in Mesoamerica.

Spider monkeys don’t live anywhere near the central Mexican highlands, including the area around what’s now Mexico City, once the home of Teotihuacan. So when University of California, Riverside, archaeologist Nawa Sugiyama and her colleagues found the 1,700-year-old skeleton of one buried alongside other offerings in a pyramid in the city’s ceremonial center, they knew it must have come from far afield—such as somewhere in the territory of what was then a neighboring political power, the Maya. And the little primate hints at a previously unsuspected history of diplomatic links between Teotihuacan’s rulers and Maya kingdoms further south.

A diplomatic gift

Sugiyama and her colleagues found the skeleton interred as part of a ritual offering deep inside one of the three pyramids that make up the Plaza of the Columns complex in the ceremonial district of ancient Teotihuacan. It was found alongside a trove of jade figurines that were traced by their chemical makeup to the Motagua Valley in what’s now central Guatemala. There were also finely worked obsidian blades and shell ornaments, along with the remains of other animal sacrifices, including an eagle, a puma, and several rattlesnakes.

No primates (other than humans) live in the region around what’s now Mexico City, and a spider monkey would have been “an exotic curiosity, alien to the high elevations of Teotihuacan,” as Sugiyama and her colleagues describe it in their paper.

Sugiyama and her colleagues say the ill-fated monkey was probably part of a gift to the Teotihuacan’s rulers from a neighboring Maya kingdom. And although the monkey was captured and brought to Teotihuacan as a sacrifice, evidence in its bones and teeth suggests that it spent at least a couple of years in the city first. Sugiyama and her colleagues suggest it was likely on public display—allowing Teotihuacan’s rulers to show off how their prestige and power had brought the city such a rare gift.

It was, more or less, the ancient version of China’s gift of two pandas, Ling-Ling and Hsing-Hsing, to the US in 1972, say Sugiyama and her colleagues.

“As millions of tourists celebrated the life of Ling-Ling and Hsing-Hsing at the National Zoo, the gift of the spider monkey who likely resided, and thus was observed by the public, at the Plaza of the Columns complex held important sociopolitical implications,” they wrote. Of course, Ling-Ling and Hsing-Hsing didn’t get buried alive in a pyramid at the end of their tenure at the National Zoo—but, well, cultural differences.

Bones from the monkey and the other sacrifices radiocarbon dated to between 250 and 300 CE. That makes the spider monkey the oldest evidence of diplomatic ties between the Teotihuacan and the Maya, and it could upend what historians know about relations between the two powers.

Hostile takeover

In 378 CE, an emissary from Teotihuacan led a delegation to the Maya city of Tikal. But if you’re looking for recent comparisons, forget about President Richard Nixon’s 1972 visit to China. Instead, picture something more like the US-led 1893 overthrow of Hawaii’s queen. The emissary, Shiyaj K’ahk’, managed to oust Tikal’s rulers and set up a new dynasty—one with distinctly Teotihuacan influence in its architecture, ceremonies, and, no doubt, its political alignment.

Historians call Shiyaj K’ahk’s regime change the Entrada. Carved glyphs and images in the stonework at a handful of other Maya cities tell us that Teotihuacan made moves against several political centers at around the same time. The carvings depicting the Entrada are the oldest record of any kind of relations between Teotihuacan and the Maya world. But the skeleton of the spider monkey buried deep in a pyramid 1,200 kilometers away at Teotihuacan suggests that things started very differently.

The Maya, in fact, may have helped build up the very kingdom that would later depose them.

Ancient DNA reveals that the monkey was female. Ratios of certain chemical isotopes in her bones suggest that she grew up wild in Maya country, then spent at least two years in captivity, eating a diet of maize and chili peppers. Worn teeth and tiny bits of wood in her dental plaque suggest she spent time gnawing at the bars of a wooden cage. Her hands and feet were bound when she died.

Based on radiocarbon dating, Maya diplomats presented their lavish gift—the spider monkey and an assortment of jade figurines and obsidian blades, among other high-end items—to the rulers of Teotihuacan between 80 and 130 years before the Entrada. And several decades later, a Maya delegation hosted a grand feast at the Plaza of the Columns. Near the offering that contained the spider monkey, Sugiyama and her colleagues unearthed more than 14,000 broken sherds of fine ceramic vessels, which dated to sometime between 300 and 350 CE, just a few decades before the Entrada.

“Such feasts are strategic arenas for alliance building,” wrote Sugiyama and her colleagues.

That alliance seems to have lasted for decades, and Maya dignitaries may even have lived at the Plaza of the Columns for a while. Mixed in with the debris and dirt used to fill in a layer of one of the complex’s pyramids, Sugiyama and her colleagues found the shattered remains of a once-elaborate mural, worked in the Maya style. And when the archaeologists pieced together the thousands of painted shards, they revealed the image of a spider monkey, wearing a belt decorated with a Maya royal emblem.

The tables turned

The spider monkey, along with the other evidence from the Plaza of the Columns, “strengthens the argument that sustained high-level diplomatic interaction with the Maya and other regional powers was a crucial factor in Teotihuacan’s ascent to prominence in Mesoamerica,” they added.

But then Teotihuacan turned on its former allies with a vengeance.

Sometime between 350 and 450 CE—around the same time as the Entrada—someone in Teotihuacan demolished the Maya mural. (That date is based on the mural shards’ position in the layers of material filling the pyramid’s interior.) Many of them still have the marks from the hammer that smashed them. Oh, and then there are the bodies.

In the Moon Pyramid, which stands near the Plaza of the Columns complex, archaeologists discovered the remains of three human sacrifice victims. They died wearing greenstone pendants carved with Maya royal symbols, and the ratios of certain chemical isotopes in their bones suggest that they originally hailed from the Maya heartland. And the sacrifice took place at around the same time as the Entrada and the destruction of the Maya mural in the nearby Plaza of the Columns.

Sugiyama and her colleagues describe these events as “a sudden shift in Teotihuacan-Maya sociopolitics,” but one could also say that nobody was monkeying around anymore.
