Researchers in France might be hot on the path of a long-lost canal that the Romans developed over 2 centuries ago while fighting the Celts.
The waterway, referred to as the Marius Canal, was constructed around 2,100 years ago within the Rhône River delta. It was the very first significant Roman water hydraulic function in what was then Gaul, preceding dams, watermills and aqueducts. According to historic accounts, it was constructed in between 104 and 102 B.C. by the soldiers of Julius Caesar‘s uncle, the basic Gaius Marius. Its building was suggested to help efforts in the Cimbrian Wars, a series of disputes in between the Roman Republic and Celtic people, the Cimbri and Teutones, that were moving south from Jutland, contemporary Denmark.
At that time, the Roman Republic was securing its brand-new province in Gaul, an area that covered what is now France, Belgium and parts of western Germany. The advancement of the Celts put that land, as well as the rest of the Roman Republic, at threat.
“The Roman general Marius came to southern Gaul in 104 B.C. to head off the risk that the Cimbri and Teutones ravaging Gaul and Spain would reach Italy,” Simon Losebyan honorary speaker in middle ages history and a professional on southern Gaul at the University of Sheffield in the U.K. who was not associated with the research study, informed Live Science. “He headed a very large force, and urgently needed to supply it by sea from Rome.”
Marius purchased the canal be constructed so it might provide his soldiers. It bypassed the treacherous Rhône River mouths and linked the city of Arles to the Mediterranean, making it possible for the safe passage of big supply boats. Eventually, the canal was a success, and the Romans beat the Cimbri and Teutones in 101 B.C. The canal was consequently talented to Rome’s ally in the area, the Greek settlement of Massalia, now Marseille, which is stated to have actually acquired substantial income from its business usage before the canal disappeared from the historic record a couple of centuries later on.
“Despite all the research carried out in recent centuries, the Marius Canal hasn’t been found,” research study lead author Joé Junckera geoarchaeologist at the University of Strasbourg in France, informed Live Science in an e-mail. It was last pointed out by the Roman author Pliny the Elder in the very first century A.D., however its traces have all however vanished.

Discovering the canal
In 2013, a geophysical study of a delta in the Vigueirat marshes simply south of Arles exposed an undersea function that researchers assumed might be an ancient canal. Subsequent excavations around the website discovered 69 pieces of Roman ceramics, 2 ancient wood stakes and 2 comprehensive cobblestone platforms. Radiocarbon dating of the stakes positioned them within the very first to 4th century A.D., while natural products within the platforms dated in between the very first century B.C. and 3rd century A.D. when the Marius Canal would have been utilized.
Considering that the website’s discovery 12 years earlier, scientists have actually been attempting to collect proof to verify whether this location actually hosts the long-lost Marius Canal.
In the brand-new research study, Juncker and his group drilled sediment cores from the ancient canal and its banks and took physical measurements to compare to the geophysical studies carried out in 2013.
“The canal length, width, orientation, sediment content and the measured radiocarbon dates confirm that it was a navigable canal in Roman times, partially excavated in a former branch of the Rhône and an ancient lagoon,” Juncker stated.
Natural tributaries in river channels are normally around 360 to 590 feet (110 to 180 meters) broad, while the brand-new analysis reveals the putative Marius Canal is much narrower at around 98 feet (30 m) large. This lines up with other Roman canals. This width would have made it possible for big Roman ships to browse the location, the authors reported in the research study, released in the April concern of the Journal of Archaeological Science: Reports
The brand-new research study reinforces the case that there was a canal here, Loseby stated. “It’s yet another indication of the Roman capacity to conceive of and undertake large infrastructural projects at speed, despite relative technological limitations.”
Both Loseby and Juncker hope future historical discoveries will even more develop whether the canal is the Marius Canal. Particularly, they hope excavations might cause the discovery of quays (landing platforms for ships) or towpaths (waterways where draft animals would tow boats), which might assist validate using the canal and the period of its usage.
“Geoarchaeology is a science full of potential, but we must bear in mind that, without confirmation from archaeological studies, it is not possible to attribute this canal to Marius for the moment,” stated Juncker. Research study there is continuous.
