Healthy snacks, grilled meats at Colosseum tailgates

An excavation of the Colosseum’s sewer systems has revealed the ancient Roman versions of Cracker Jacks and ballpark franks and it’s melon and mutton. The study aims to learn more about how the ancient sewer and hydraulic systems operated under the Flavian Amphitheater with a particular focus on solving the mystery of how the underground was flooded during water spectacles. In January 2021, wire-guided robots were sent to video record and laser scan the drains and sewers under the arena. A year later, a stratigraphic excavation of the south collector of the sewer network began, clearing 230 feet of muck that contained archaeological treasure in the form of ancient garbage.

Sewers are often constipated with archaeological material from the very bowels of daily life in the ancient city, and the sewers under the Colosseum contain a unique variety of organic remains left by both the spectacles and the spectators. The excavation of the south collector brought in a rich harvest: the discarded remains of chestnuts, walnuts, pine nuts, hazelnuts, figs, peach pits, plum pits, cherry pits, olive pits, blackberries, elderberries, melon seeds and grape seeds, evidence of the snacks consumed by the audience in the bleachers during the games. They didn’t just have snacks in the stands. It seems spectators rigged up braziers so they could grill up some meat, mostly pork and mutton, as they watched people and animals being butchered for sport.

Remains of animals who starred in the games were found as well. There were bones of bears of different sizes, possibly used in acrobatic displays, lions, leopards, ostriches and deer, likely used in the venationes (staged animal hunts). There were also dogs of different sizes. The smallest was less than a foot in height, but stocky and strong, a predecessor of the dachshund. Remains of plants that grew in the Colosseum showed a wide degree of biodiversity, ranging from blackberries to boxwoods and laurels. Some of the plants were spontaneous growth (the international animal and human feces spread led to hundreds if not thousands of different non-native plants taking root in the Colosseum); the evergreens were probably deliberately planted for landscaping.

The excavation also recovered artifacts. As you would find under the sewer grates of the sports arena today, there’s a lot of spare change down there. Archaeologists unearthed 53 bronze coins from the Late Imperial era, and a rare orichalcum sestertius struck in 170-171 A.D. to commemorate the 10th anniversary of the ascension of Marcus Aurelius to the imperial throne. Personal objects found include bone game dice, a bone pin and clothing elements (shoe nails, leather, studs).

I can’t embed this video from the Facebook page of the Archaeological Park of the Colosseum, but do yourself a favor and follow the link because it shows urban spelunkers from the organization Roma Sotterranea (Underground Rome) exploring the sewer, squeezing through uncomfortably tight, mucky spaces and pointing out the brick stamps inscribed with the names of the makers which identify the period when that stretch of construction or repairs was done.

Celtic gold hoard coin stolen in museum heist

A hoard of Celtic gold coins from the 1st century B.C. was stolen in a daring smash-and-grab burglary from the Celtic and Roman Museum in Manching, southern Germany. Thieves made away with 483 coins in the early hours of Tuesday, November 22, and Bavaria’s State Criminal Police Office have launched an international investigation to find the perpetrators and the treasure they stole.

At 1:17 AM, several fiber optic lines were cut at a telecom hub a kilometer away from the museum, severing internet and telephone service to 13,000 homes and businesses in Manching, including at the Celtic and Roman Museum. This also cut off the alarm linking the museum’s security system to the police. Exactly nine minutes later at 1:26 AM, an emergency exit at the museum was pried open and two display cases made of bulletproof safety glass were broken into. At 1:33 AM, the thieves disappeared into the night with the entire hoard of gold coins. Nobody noticed the loss until the museum staff arrived for the work day. Police were alerted and arrived around 9:45 AM.

The largest Celtic gold find to appear in the 20th century, the hoard was discovered in 1999 years ago at the site of an ancient Celtic settlement in Manching. Found in a sack buried under the foundations of a building, the bowl-shaped coins were struck from Bohemian river gold, evidence of how Iron Age Manching was connected to trade networks in central Europe.

It has been on display at the museum since 2006 and is its flagship attraction. The authorities fear that in its original form, the coin hoard will be impossible for the thieves to sell, and that even though their historical value tops 1.6 million euros, the coins will be melted down to sell for their mere gold value. Each coins weighs 7.3 grams for a total hoard weight of about four kilos, which at current prices would be worth about 250,000 euros.

Because of the delay in discovery of the theft, police missed crucial hours of investigations. There are now dozens of investigators working on the case.

Both have been blamed on a Berlin-based crime family.

“Whether there’s a link we can’t say,” he added. “Only this much: we are in touch with colleagues to investigate all possible angles.”

Bavaria’s minister of science and arts, Markus Blume, said evidence pointed to the work of professionals.

“It’s clear that you don’t simply march into a museum and take this treasure with you,” he told public broadcaster BR. “It’s highly secured and as such there’s a suspicion that we’re rather dealing with a case of organized crime.” […]

Limmer, the deputy police chief, said Interpol and Europol have already been alerted to the coins’ theft and a 20-strong special investigations unit, codenamed ‘Oppidum’ after the Latin term for a Celtic settlement, has been established to track down the culprits.

Coins with only mention of Roman “emperor” authenticated

Coins that are the only evidence of the historicity of the otherwise unrecorded Roman so-called emperor Sponsian have been found to be authentic 3rd century issues. The history of these coins is sketchy and there are some stylistic anomalies that have cast doubt on their authenticity since they first emerged in 1713. Plus, they portray an alleged emperor that appears nowhere else on the historical or archaeological record.

The coins were first documented by Carl Gustav Heraeus (1671–1725), Inspector of Medals for the Imperial Collection in Vienna, in March of 1713. He recorded the acquisition of eight coins found in Transylvania. Another 15 coins that match Heraeus’ description came to light starting in 1730, and scholars believe they were part of a wider assemblage that was sold to a number of different collections over the years, including The Hunterian museum at the University of Glasgow.

Among the four coins from the wider assemblage now in the collection of The Hunterian is one featuring the unknown “emperor” Sponsian. It is designed in the style of coins from the mid third century, but the design on the reverse is a copy of a Republican-era silver coin from the 1st century B.C. That reverse design would have been close to 400 years old when the Sponsian coin was made. That and other atypical features of the wider assemblage coins have led scholars to peg them as fakes, perhaps the work of a talented forger working in early 18th century Vienna who duped Heraeus.

A new study published in the journal PLoS ONE took a closer look at the Sponsian coin in The Hunterian using modern imaging techniques to detect evidence of forgery like artificial aging methods. The surface scratches and wear and tear on the coin could have been created by forgers abrading the coin, but earthen deposits were found on the coin, and forgers do not customarily cram or glue dirt onto their fakes.

They applied visible light microscopy, ultra-violet imaging, scanning electron microscopy, and reflection mode Fourier transform infra-red spectroscopy to the four coins and, for comparison, two undoubtedly authentic Roman gold coins.

The analysis revealed deep micro-abrasion patterns typically associated with coins that were in circulation for an extensive period of time. The researchers also analyzed earthen deposits on the coins, finding evidence that after extensive circulation, the coins were buried for a prolonged period before being exhumed. Together, the new evidence strongly suggests the coins are authentic.

Considering the historical record alongside the new evidence from the coins, the researchers suggest that Sponsian was an army commander in the Roman Province of Dacia during a period of military strife in the 260s CE.

So he wasn’t exactly a Roman emperor in the typical sense of the term. He was a local ruler of a relatively remote Roman province that happened to be a gold mining outpost, giving him access to the raw material for minting his own gold coins while the chaos of invasions distracted the legitimate emperors, such as they were during the Crisis of the Third Century.

1,700-year-old spider monkey found in Teotihuacan

Photo courtesy the Project Plaza of the Columns Complex.The remains of a spider monkey have been discovered in the pre-Hispanic central ceremonial complex of Teotihuacan, Mexico. Spider monkeys were exotic animals not native to the arid highlands of Central Mexico, and this one was likely a diplomatic gift from Teotihuacan’s Maya neighbors. Radiocarbon dated to the second half of the 3rd century A.D., the spider monkey is the earliest example of a primate in captivity in the Americas, and the first evidence of gift diplomacy between Teotihuacan and the Maya city-states in the Early Classic period (250-550 A.D.).

Located about 25 miles northeast of what is now Mexico City, Teotihuacan was a religious, cultural and commercial center in the Mexican Highlands from the 1st century until its collapse around 500 A.D. At its peak in 450 A.D., it was the largest and most populous city in the ancient Americas with a conservative population estimate of 150,000. Half of the people in the Valley of Mexico lived in Teotihuacan.

It was not ruled by dynastic kings like the Maya polities. We don’t really know what form of government ran Teotihuacan, but we know it had powerful warlords because in the late 4th century, one of them conquered the Maya power center of Tikal 600 miles away. Maya inscriptions record Teotihuacan contact with the Mayan world reached as far as Honduras, perhaps even conquering city-states there, and certainly spreading its cultural presence, notably its characteristic obsidian crafts and architectural styles.

The complete skeleton of the spider monkey was unearthed at the Plaza of Columns Complex of Teotihuacan. It is a sacrificial offering deposited at the temple with its hands tied behind its back and feet tethered together. This type of binding was common among human and animal sacrifice victims buried alive. Next to it were found the complete skeletal remains of a golden eagle, the skull of a puma, several rattlesnakes and ritual objects (greenstone figurines, shell artifacts, obsidian blades). The monkey was female and between five and eight years old at the time of death. Analysis of the remains found that it was captured before the age of three and lived in captivity for more than two years after that. It ate a diet of maize, arrowroot and chili pepper, all of which had to have been prepared for it by humans. Before its arrival in Teotihuacan, it lived in a humid environment and ate plants and roots.

This finding allows researchers to piece evidence of high diplomacy interactions and debunks previous beliefs that Maya presence in Teotihuacán was restricted to migrant communities, said [anthropological archaeologist Nawa] Sugiyama, who led the research.

“Teotihuacán attracted people from all over, it was a place where people came to exchange goods, property, and ideas. It was a place of innovation,” said Sugiyama, who is collaborating with other researchers, including Professor Saburo Sugiyama, co-director of the project and a professor at Arizona State University, and Courtney A. Hofman, a molecular anthropologist with the University of Oklahoma. “Finding the spider monkey has allowed us to discover reassigned connections between Teotihuacán and Maya leaders. The spider monkey brought to life this dynamic space, depicted in the mural art. It’s exciting to reconstruct this live history.”

The find has been published in the journal Proceedings of the National Academy of Sciences and can be read in its entirety here.
