Underwater survey reveals new discoveries in sunken town of Baia

Published

Underwater archaeologists have been conducting ongoing research at the sunken Roman town of Baia, revealing new discoveries in the Terme del Lacus area.

Baiae is an archaeological park consisting of a partially sunken town from the Roman period, located on the shore of the Gulf of Naples in the present-day comune of Bacoli in Italy.

Baiae developed into a popular Roman resort which was visited frequently by many notable Roman figures, such as Gnaeus Pompeius Magnus (also known as Pompey the Great), Julius Caesar, Gaius Marius, Lucius Licinius Lucullus, Hadrian, and Septimius Severus.

The town would never attain a municipal status, but instead gained a reputation for a hedonistic lifestyle. This is supported by an account by Sextus Propertius, a poet of the Augustan age during the 1st century BC, who wrote that Baiae was a “vortex of luxury” and a “harbour of vice”.

Due to the position of the town on the Cumaean Peninsula in the Phlegraean Fields, an active and volatile volcanic region (which the Romans believed was the home of the Roman god of fire, Vulcan), local volcanic bradyseismic activity raised and lowered the geology on the peninsula that resulted in the lower parts of the town being submerged.

Underwater archaeologists from the Campi Flegrei Archaeological Park and Naumacos, have been conducting a survey of the Terme del Lacus area, revealing a block of structures covering 60 metres in length. The team also found stone colonnades, marble columns, and a portasanta marble column, which was imported during antiquity from the island of Chios in Greece.

A large piece of marble opus sectile flooring has also been identified, still rendered with portasanta and white marble in a chromatic alternating pattern. This currently appears as the most indicative dating element, being the typology and implementation referable to the Late Antiquity age.

Previous surveys of the area in 2013 uncovered an ornate statue representing Apollo, the Greek/Roman god of archery, music and dance, truth and prophecy, healing and diseases, the Sun and light, poetry, and more.

Archaeologists reveal hundreds of ancient monuments using LiDAR

A new study published in the journal Antiquity has revealed hundreds of previously unrecorded monuments at Baltinglass in County Wicklow, Ireland.

The Baltinglass area (known as ‘Ireland’s Hillfort Capital’) has a high density of Early Neolithic and Late Bronze Age monuments, however, very little evidence has been recorded that dates from the Middle Neolithic period.

According to Dr James O’Driscoll from the University of Aberdeen, the ancient landscape around Baltinglass was incredibly important to the Early Neolithic people, however, the lack of Middle Neolithic evidence suggests that this importance was lost until the Late Bronze Age.

Using advanced LiDAR technology, archaeologists have created detailed three-dimensional models, revealing hundreds of ancient sites that that been destroyed by thousands of years of ploughing.

Light Detection and Ranging (LiDAR), is a method of remote sensing using light in the form of a pulsed laser to measure ranges (variable distances) to the Earth. The differences in the laser return times and wavelengths can be used to compile a 3-D digital map of the landscape.

The most significant discovery from the survey is a cluster of five cursus monuments, the largest example found in both Britain and Ireland. The purpose of such monuments are speculative, but some theories propose that they were used in rituals connected with ancestor veneration, that they follow astronomical alignments, or that they served as buffer zones between ceremonial and occupation landscapes.

According to the study authors: “These five cursus monuments are clearly aligned with burial monuments in the landscape, as well as the rising and setting sun during major solar events such as the solstice.”

“This may have symbolised the ascent of the dead into the heavens and their perceived rebirth, with the cursus physically setting out the final route of the dead, where they left the land of the living and joined the ancestors beyond the visible horizon,” said Dr O’Driscoll.

Archaeologists use revolutionary GPR robot to explore Viking Age site

Archaeologist from NIKU are using a revolutionary new GPR robot to explore a Viking Age site in Norway’s Sandefjord municipality.

The robot has been developed as part of a collaboration between AutoAgri, Guideline Geo/MÅLÅ, and NIKU, and uses the I-Series autonomous implement carrier model fitted with the latest high-resolution, multi-channel ground-penetrating radar system.

GPR is a geophysical method that uses radar pulses to image the subsurface. It is a non-intrusive method of surveying archaeological features and patterning beneath the subsurface.

Initial testing of the robot was conducted in Trøndelag Vinnan in Stjørdal municipality, which according to the researchers has demonstrated increased efficiency and provides accurate mapping solutions.

The new robot system has an antenna that produces a much higher resolution than traditional georadar systems, which for the first time can be interpreted in real time.

According to Erich Nau from NIKU, previous systems had to be driven around archaeological sites, however, the new GPR robot only needs a short hour to map the driving route, then the robot does the rest on its own.

The robot is being used as part of a new study of a Viking Age trading post at Heimdalsjordet near the Gokstadhaugen ship burial in Sandefjord.

The non-intrusive approach will provide a detailed picture of the subsurface that previous surveys could have missed, such as traces of longhouses, land plots, roads, wharves and burials.

“This collaboration gives us a unique opportunity to explore and understand our historical landscape with new and advanced technology. We look forward to uncovering new discoveries that can give us valuable insight into our rich cultural heritage,” says Petra Schneidhofer, archaeologist in Vestfold county municipality.
