Archaeology has uncovered many secrets from the ancient world. But the Earth has a bad habit of eroding the past, making it difficult to piece together the stories of our ancestors. In the past couple of centuries, we’ve discovered Roman artifacts in the Americas, found ancient Greek cities in what was once thought to be the backwater of Ancient Greece, puzzled over the success of the Incan economy, and have long searched for the core of history’s first true empire.
These mysteries prove that humanity needs to keep digging to uncover the truth, lest we repeat our past mistakes.
10. The Romans May Have Discovered the New World
But the recent discovery of certain artifacts around the Americas has been putting this idea into question. We’re talking about Roman artifacts discovered both on the continent and in her waters, such as a sunken Roman ship in Brazil’s Guanabara Bay, terracotta amorphae, and tall jars clearly made during the Roman Empire’s rule.
The jars themselves date back to the 1st or 3rd century BC. Wine, grains, and olive oil were stored inside these types of jars and transported all over the Roman Empire.
Just outside Mexico City, another terracotta artifact thought to belong to the ancient Roman Empire was found. The artifact is a carved head, and experts say it’s a depiction of a Roman during the Hellenistic period, dating all the way back to 200 AD.
Finally, the discovery of several caches of Roman coins have been found buried throughout North America, and date back to the 16th century. Though some doubt has been raised as to the legitimacy of the coins, many archaeologists have seriously begun to consider the possibility that Roman settlers discovered the Americas in the ancient past.
Though, who, how, and why is still a mystery.
9. Ancient Roman Cults
Cults in the ancient Roman Empire have baffled archaeologists and historians alike because the evidence of their writings and artifacts have been poorly preserved. A mystery religion is defined by historians and archaeologists as one that offers individuals a religious experience not practiced officially by the state. The Mithraic cult, which historians seem to agree existed sometime before Christianity began to take over Rome as the primary religion, had most of its writings and artifacts destroyed after Christianity took hold. Though most scholars agree that before this, the Roman government tolerated the Mithraic cult, as its views supported the government at the time.
For every Roman god, there was probably one or two cults devoted to them, most of them starting as a family or a divergent version of the official state religion taken on by a clan. These cults would persist until the state absorbed them. Most of them featured an initiation ritual (just like today’s cults) and were typically performed inside a large sanctuary.
Just how many of these cults existed in the ancient world, and what they believed, however, remains a mystery.
8. The Lost City of Paititi
The Lost City of Paititi and the quest to find it has claimed many explorer’s lives. The legend even inspired Sir Arthur Conan Doyle’s “The Lost World.” This lost city of gold has eluded every treasure hunter, archaeologist, and would-be explorer who have gone searching for it. Finding this city would inform much about the ancient Inca civilization which thrived between 1400 and 1533 AD, extending across western South America.
After the discovery of a letter to the pope in the Vatican archives from a missionary named Andres Lopez concerning the location of a large city rich with gold, silver, and jewels, the search for the city was renewed. Lopez’s letter claimed the city was located in the middle of the jungle and called Paititi by the local indigenous tribes. The pope and the Vatican kept the location secret for decades, but in 2016 a new expedition was set in motion. While that expedition turned up questionable artifacts in a site which is still being disputed today, the discovery of previously hidden cities throughout the Amazon (thanks to a combination of ground-penetrating radar and illegal logging and deforestation) has helped to keep the renewed fervor for the lost city alive.
7. The Economy of the Incas
Most historians agree that the Incan economy was one of the most successful in the ancient world, but perplexingly, they did not use money or gold, and only seemed to trade with outsiders. A lot of what we know of the Incas comes from the Spanish conquistadors who crushed their armies (after unleashing a plague of smallpox upon them, wiping out 90% of their population), so, much of how the Incas functioned as a society has been lost to time.
Still, the question remains how the Incas were able to create such a thriving economy without currency or even trade. Some historians believe that the secret to their great wealth came from the unique tax system they used, which required every Incan citizen to pay labor to the state. Strangely, wealthy Inca who passed away were able to continue owning property, and some historians jest that it’s almost as though they invented the idea of corporations-as-people without ever creating a market economy.
Because of the difficult terrain and harsh environment of the Amazon, much of the Incas way of life was dictated by a need to keep their people from starving, rather than developing markets and traditional forms of economics. At least, that’s what historians believe based on the little evidence that survives of the Incan civilization. Much of it still remains a mystery.
6. The Lost City of Tenea
The Lost City of Tenea was said to have been founded by prisoners of the legendary Trojan War, but it’s thought that the city was abandoned some time in the 4th century BC. Archaeologists have been on the hunt for signs of the legendary city since a sarcophagus was discovered in the Greek village of Chiliomodi in 1984.
More recently, though, archaeologists claim that the city has finally been discovered. An archaeological effort in the modern village of Chiliomodi began in 2013, leading to excavators of the site there to proclaim that proof of the legendary city was at last discovered after a series of rare coins, seven graves, and carefully constructed structures composed of clay, stone walls, and marble floors were unearthed.
Whether or not the Trojan War actually happened is up for debate, but the things learned in Tenea may provide a clue, especially if proof is found that shows that the city was indeed settled by those fleeing from their defeat in the Trojan War. Whether this was at the hands of legendary Odysseus or not, remains to be seen, and the city itself holds many mysteries which archaeologists are eager to uncover.
5. The Mystery of Teotihuacan
The ancient city of Teotihuacan stretches out for 20 square kilometers, contains nearly 2,000 single-story structures which appear to have been homes, and various impressive buildings like pyramids. The discovery of Teotihuacan may have been a major archaeological find, but its existence poses some problems for scholars, as it’s unknown who exactly built it. Originally, it was thought that the Toltec civilization must have built the city, but this was refuted when it was discovered that Teotihuacan peaked long after the Toltecs vanished.
Other theories range from the Totonacs having built the city, or immigrants fleeing the eruption of a volcano, but no conclusive theory has emerged. The city contains the hints of Mayan, Mixtec, and Zapotec cultures, further adding to the mystery.
Whoever built the city, scholars are certain Teotihuacan was originally founded in 400 BC, with the largest structures seeing their completion by 300 AD, and the city and culture reaching its peak nearly 100 years later with a population of over 200,000 inhabitants.
4. The Mystery of the Origin of the Sumerian Language
The Sumerian language appeared as early as 4000 BC and dominated Sumerian civilization for nearly 1,000 years, before being mostly replaced by Akkadian. The language was pictographic (or cuneiform) meaning that individual images represented whole words, phrases, or sentences, (much like Egyptian hieroglyphs, or later logographic languages like Chinese and Japanese).
This language is quite mysterious because beyond Akkadian there are no known ancestral forms of communication connected to it. Although some linguists think that Sumerian could be related to the Uralic languages such as Finnish and Hungarian, this view isn’t shared throughout the academic community.
Scholars suggest that, if the Sumerian people did not originate from the area of Mesopotamia, then it’s possible that their language could have been influenced by an older, still undiscovered language, but this is just a hypothesis.
3. The Fall of the Akkadian Empire
The Sumerian empire eventually fell to Sargon the Great, who established one of history’s first empires. The Akkadian Empire was ruled from Sargon’s city of Akkad. The Akkadians would succeed in nearly stamping out the Sumerian language and Sargon would be succeeded by several other rulers after his death. But sometime after Shar-Kali-Sharri took rule of the Akkadian empire, things took a turn for the worse, and eventually, what was once the world’s first true empire would collapse in 2154 BC.
What caused it, though, is a bit of a mystery.
Historians present three theories for the fall of Akkadia.
The first is that the invasion of the Gutians (a people who dwelled in the mountains) proved to be too much for the disorganized Shar-Kali-Sharri, who was already having difficulty maintaining order in the wake of his father’s death. He also waged a seemingly indefinite war with the Elamites and the Amorites at the same time the mountain people were invading.
The second is that a combination of a poor harvest, a great famine, and a great drought may have contributed or caused the collapse outright. In 2019, a study of fossil coral records from Oman provided evidence that winter dust storms, along with a longer winter than usual may have sealed the Akkadian Empire’s fate.
The third possibility is that a meteor collision with the Earth set in motion drastic changes to the Earth’s weather, causing the climate to change around an already struggling empire.
2. The Lost Ruins of Vlochos
In 2015, archaeologists uncovered what appeared to have been the site of a Greek village called Vlochos. At the time, they wrote the discovery off as of no importance, thinking that the remains atop the hill were nothing more than the remains of a Greek village. That was until they discovered the remnants of towers, gates, and a city grid which hinted at there being a deeper story to the ruins. With new information, the site is now considered to have been the center of a Greek city, one which flourished sometime during the 4th century BC, and was abandoned in the 3rd century BC.
Why it was abandoned, though, remains a bit of a mystery. Archaeologists and scholars think that a likely candidate is the invasion of Roman forces. Using ground-penetrating radar, archaeologists hope to uncover more of the lost city’s secrets.
What is interesting about this site is that this area of Greece was previously thought to have been a backwater of the Ancient Greek world, so archaeologists and scholars haven’t really paid much attention to it.
Who knows what other mysteries lie in wait for them?
1. The City of Akkad
No one knows where the city of Akkad was located. We know a great deal about the man who supposedly built it, Sargon the Great, and the empire he ruled, but the capitol city itself has long eluded scholars and archaeologists.
It has been told that Sargon the Great built the city along the bank of the western Euphrates River, possibly between the cities of Kish and Sippar, though Mari and Babylon have been offered as other potential possibilities as well.
There are a number of excavation sites which scholars think could be candidates for the City of Akkad. Most of these places are situated east of the Tigris, which is part of the Euphrates, but there is much debate as to which of these might be the true site of the capital of the Akkadian Empire.
How the city fell and where it was located is almost as great a mystery as to how the Akkadian Empire fell.
