The crossbow triggers and parts found in Emperor Qin's mausoleum.
Sept. 12, 2011 --
In the search for buried history, archaeologists pour their resources into uncovering the remnants of the distant past. With know-how, persistence and a little luck, archaeologists can push aside dirt and rock and find an artifact of historical significance. Although chance plays a big role in unearthing history, archaeological treasures have been stumbled upon purely by accident, often by those outside the scientific community. In these photos, explore several particularly serendipitous finds of unique artifacts, some of which reach as far back as prehistory.
On Sept. 12, 1940, four teenagers followed their wayward dog into a cave complex near the village of Montignac in southwestern France. To their surprise, the caves hosted something remarkable: nearly 2,000 paintings and etchings of animals, humans and abstract shapes on the walls dating back between 15,000 and 25,000 years. Known as the Lascaux caves, the complex features figures depicted in surprising detail given the age of the illustrations. Animals portrayed on the cave walls included horses, stags, bison and felines. Archaeologists believed the caves were used for ritualistic purposes. Some parts of the illustrations even appear to construct a narrative, but what they mean exactly has yet to be deciphered. The caves were open to the public in 1948, but closed in 1963 in order to preserve the site from damage.
The Dead Sea Scrolls are a collection of over 800 biblical texts made of animal skin and papyrus. Dating to around 2,000 years ago, between the years 200 B.C. and 70 A.D., the scrolls could well be the oldest such documents in existence and have deepened historians' understanding of religious history. These documents may have been lost to history had a Bedouin shepherd named Muhammed edh-Dhib and his cousin not stumbled upon the first manuscripts along the northern shore of the Dead Sea at a remote site known as Qumran in 1947. The last fragments of the Dead Sea Scrolls collection was uncovered in the mid-1950s. Although the scrolls have been extensively studied and translated, one big mystery remains: Who exactly wrote them?
As Napoleon Bonaparte's army marched through north Africa during his campaign in Egypt, they stumbled upon what would become known as the Rosetta Stone, after the town where it was discovered. Within Bonaparte's army was a squadron of scholars called Institute of Egypt, also known as the Scientific and Artistic Commission. As the military settled around the Nile Delta, the Institute explored local ruins and artifacts. After the discovery of the stone in 1799, several copies of the inscriptions on its face were made, since no one could read them at the time. By 1802, the Greek and Demotic portions of the stone had been deciphered by scholars. The hieroglyphics posed a different challenge all together, however, and it would take 20 years before French scholar Jean-François Champollion announced that he had cracked the code. By deciphering the hieroglyphs, Champollion opened a whole new door to understanding the civilization of ancient Egypt. The Rosetta Stone is currently kept in the British Museum.
In case you don't know what a geoglyph is, ancient Peruvians went through the trouble of leaving a picture-perfect definition. Known as the Nazca Lines, these giant carvings into the Earth were only discovered by airplane in the 1930s. Located in the Nazva desert in southern Peru around 250 miles (400 kilometers) south of Lima, the geoglyphs resemble a number of animals including a spider (as seen here), a condor, a monkey, a tree, as well as human figures and geometric patterns. Why exactly indigenous tribes living in the area between 100 B.C. and 650 A.D. felt compelled to produce these works remains a mystery, though archaeologists agree that it is likely tied to religious customs.
In 1991, German tourists stumbled upon a frozen body in a glacier on the Ötztal Alps between Italy and Austria. Although they originally thought the corpse to be the result of a recent death, the iceman mummy, named Ötzi, in fact dated back 5,300 years. Since Ötzi's discovery, the mummy has been extensively studied. Scientists have learned everything from his last meal to his cause of death to his possible occupation and they have even made reconstructions of his face. Ötzi died in the spring as a result of an arrowhead striking his left clavicle artery. He likely received a ceremonial burial and was found beside tools and other personal items.
Over the years, metal detector enthusiasts, particularly those in the United Kingdom, have uncovered archaeological treasures buried beneath the Earth. In 2009, 30-year-old Nick Davies hauled in 10,000 ancient Roman coins that he had found inside a clay pot buried in Shropshire, U.K. That same year, a trove of 1,500 gold and silver pieces dating back to the Dark Ages were found on a farmer's field in the western region of Staffordshire, England. Last year, 63-year-old David Crisp uncovered 52,000 ancient Roman coins, later given a value of around $1 million, in a clay pot in southwestern England.

In 1986, divers stumbled upon a nearly 2,000-year-old Roman shipwreck some six miles off the coast of the town of Grado, Italy. Measuring 55 feet long and 16 feet wide, the small trade vessel was stocked with 600 amphorae, or vases, packed with sardines and other fish. Further study of the shipwreck revealed that the ancient Roman engineers also had built in a hydraulic system that allowed the ship to carry an aquarium with live fish.
One of the most astounding archaeological discoveries of the 20th century is arguably the life-size terra-cotta army buried alongside China's first emperor. Now, scientists have figured out how the bronze triggers for the crossbows of the 8,000 terra-cotta warriors were manufactured.
Teams of craftspeople worked in small groups to produce the bronze pieces in batches for the tomb of ancient Emperor Qin Shi Huang, according to a new study detailed in the March issue of the journal Antiquity.
Prepared for the afterlife
Historical documents suggest that soon after Emperor Qin Shi Huang ascended to the throne in 246 B.C., he began work on his tomb near Xi'an, China. When the tomb was first unearthed in the 1970s,it revealed thousands of lifelike terra-cotta statues of artisans, musicians, officials, horses and soldiers. The epic effort conscripted 700,000 laborers, many of whom were convicts or people who were in debt to the empire, said study co-author Xiuzhen Janice Li, an archaeologist who was at the University College London at the time of the new work and is now at the Emperor Qin Shi Huang’s Mausoleum Site Museum in China.

The massive undertaking had an important goal: ensuring the emperor's military power and resources in the afterlife.
As part of the huge project, craftspeople sculpted about 8,000 colorful warriors — likely using real human beings as inspiration — and those warriors wore stone armor and "wielded" lances, swords and crossbows.
But it wasn't clear exactly how these ancient weapons were made. The crossbows were made of wood or bamboo that rotted long ago, and only the tips and triggers for the bows remained, Li told Live Science.
To learn more about how the massive trove was built, Li and her colleagues visually inspected and measured about 216 of the five-part crossbow triggers from the mausoleum.
The lack of wear on the metal pieces suggests the weapons were never used in actual battle, but were instead built solely for the tomb, the researchers said.
In addition, the team analyzed the spots where triggers were found in the tomb, as well as the variation in the size and shape of the pieces.
The pieces were mostly uniform, suggesting the interlocking trigger parts were made in the same or nearly-identical molds and produced in small batches. Each batch of the trigger pieces was likely then assembled in small cells, or workshops, perhaps headed by an overseer. That model contrasts with the "assembly line" hypothesis that some archaeologists thought might have been used.
Mirror of society
The organization into small workshops was similar to the structure the emperor imposed on the rest of society in ancient China, said study co-author Marcos Martinón-Torres, an archaeologist at the University College London.
"He abolished any privileges inherited by blood, and the population was divided in small groups that were collectively responsible for their adherence to imperial laws," Martinón-Torres wrote in an email to Live Science. "For example, if someone in one of these groups committed a crime, all of them were held responsible, unless they reported the culprit and allowed them to be punished."
The manufacturing technique used in the workshop also may have been used by weapon makers for the Emperor of Qin's real armies, though that's just speculation, Martinón-Torres said.
"The cellular workshop model we postulate for the weapons manufacture in the mausoleum would have also offered useful flexibility for armies on the move," he said.
