Roman military camps and evidence of silver mining found in the Bad Ems area
Archaeologists from the Goethe-Universität Frankfurt am Main have uncovered two Roman military camps near the town of Bad Ems, in Rhineland-Palatinate, Germany.
Evidence of subsurface features were first identified in 2016 from a series of crop marks, leading to a drone photography survey of the site and geomagnetic prospecting.
The survey revealed a military camp covering an area of 19.7 acres, that could house up to 3,000 garrisoned soldiers living in tents during the duration of when the camp was occupied.
Within the interior is a building consisting of a warehouse and storeroom intended as a solid build, however, evidence of burning suggests that the site was only occupied for a few years and was never completed.
The researchers have also identified a second camp 1.2 miles away on the opposite site of the Emsbach Valley, which has a defensive construction of sharpened wooden stakes surrounded by a tapering perimeter ditch.

The site of the second camp was first explored in 1897, revealing evidence of processed silver ore, wall foundations and metal slag, that led to the assumption that a Roman smelting works was once located there.
New excavations have determined that the supposed furnace is actually a watchtower, belonging to a small military camp that could hold a garrison of around 40 soldiers.
In the writings of the Roman historian, Tacitus, he describes how the Roman governor, Curtius Rufus, had failed in an attempt to mine silver ore in the area around AD 47, possibly because the yield returns of silver were far too low to warrant the mining operations.
The researchers have confirmed the historical narrative by the discovery of a shaft-tunnel system for exploratory mining. The tunnel falls short of the Bad Ems passageway by only a few metres, a large deposit that in modern times has yielded 200 tons of silver.
The proximity of the camps to the mine suggests that they were constructed to provide security to the mining operations of the region, but once all mining was abandoned, the camps were burnt and the soldiers stationed elsewhere.

A study of archaeological sites in Winchester, England, has revealed that red squirrels served as a host for Mycobacterium leprae strains that caused leprosy in people.
Leprosy is one of the oldest recorded diseases in human history and is still prevalent to this day in Asia, Africa, and South America.
It has previously been suggested that the extensive trade of red squirrel fur, greatly valued during medieval times, could have contributed to the leprosy epidemic in medieval Europe.
The results of the study, published in the journal Current Biology, studied 25 human and 12 squirrel samples from two medieval sites in Winchester.
During this period, the city had strong connections to the fur trade and housed the leprosarium, a hospital that treated people with Hansen’s disease (leprosy) caused by Mycobacterium leprae bacteria.
Verena Schuenemann of the University of Basel in Switzerland, said: “With our genetic analysis we were able to identify red squirrels as the first ancient animal host of leprosy.”
The study found that the medieval red squirrel strains were more closely related to human strains in Winchester, rather than to modern squirrel strains from England – suggesting an independent circulation of Mycobacterium leprae strains.
“Our findings highlight the importance of involving archaeological material, in particular animal remains, into studying the long-term zoonotic potential of this disease, as only a direct comparison of ancient human and animal strains allows reconstructions of potential transmission events across time,” says Sarah Inskip of the University of Leicester, UK, a co-author on the study.

Archaeologists from the Uncovering Roman Carlisle project have discovered a rare lump of Tyrian purple at the grounds of the Carlisle Cricket Club in Carlisle, England.
The project is a community supported excavation by Wardell Armstrong, focusing on uncovering a Roman bath house found in 2017.
The bath house is located near the Roman fort of Uxelodunum (meaning “high fort”), also known as Petriana, in the Carlisle district of Stanwix.
Uxelodunum was constructed to control the territories west of present-day Carlisle and an important crossing on the River Eden. The fort was garrisoned by the Ala Petriana, a 1,000-strong cavalry unit, whose members were all granted Roman citizenship for valour on the field.
Previous excavations at the bath house have discovered colossal sandstone heads depicting Roman gods, in addition to engraved gems known as intaglios, figurines, animal bones, and imperial-stamped tiles.
During the latest season of excavations, archaeologists found a mysterious lump of a soft purple substance. The substance was tested by researchers from Newcastle University, revealing that it contained levels of Bromine and beeswax.
According to the researchers, the substance is Tyrian purple, a coloured dye associated with the Imperial Court in the Roman Empire. Tyrian purple is secreted by several species of predatory sea snails in the family Muricidae, rock snails originally known by the name Murex.
Frank Giecco, Technical Director at Wardell Armstrong, said: “For millennia, Tyrian Purple was the world’s most expensive and sought after colour. It’s presence in Carlisle combined with other evidence from the excavation all strengthens the hypothesis that the building was in some way associated with the Imperial Court of the Emperor Septimius Severus which was located in York and possibly relates to an Imperial visit to Carlisle.”
“It’s the only example we know of in Northern Europe – possibly the only example of a solid sample of the pigment in the form of unused paint pigment anywhere in the Roman Empire. Examples have been found of it in wall paintings (like in Pompeii) and some high status painted coffins from the Roman province of Egypt,” said Giecco.
