In a remarkable archaeological discovery, a well-preserved mosaic from an ancient Roman villa has been uncovered on the seabed near Naples. The mosaic, believed to have once adorned the villa's decorated porch or "protiro," was found in the waters off the coast, according to the Campi Flegrei Archaeological Park, a part of the Italian Ministry of Culture.

The villa, located in the renowned spa town of Baiae, was a popular destination during the late Roman Empire and boasted illustrious owners such as Julius Caesar and Emperor Nero. However, the land that housed the villa, along with several other structures, became submerged due to the geological phenomenon known as bradyseism, which causes the ground to rise or fall under pressure.

Initial investigations indicate that the mosaic floor is primarily constructed using irregularly shaped pieces of reused marble, a common technique employed during the 3rd to 5th centuries CE. The floor, however, suffered significant damage as the room's walls, towering over 10 meters (32 feet) high, collapsed onto it.

Efforts are currently underway to unearth and restore more sections of the mosaic, with some portions already removed and cleaned on land. The ultimate goal is to reconstruct an entire section of the floor, according to the authorities involved in the excavation.

Experts estimate that the mosaic would have been installed towards the end of the Roman Empire, shortly before the bradyseism event that submerged these enchanting wonders beneath the sea. The area, now a popular diving destination, showcases numerous submerged ruins, offering visitors a glimpse into Baiae's rich history.

However, amidst the excitement of this discovery, concerns arise as the region is prone to seismic activity. Italy's National Institute of Geophysics and Volcanology (INGV) reports that seismic activity in the area has been intensifying since December 2022. Experts fear that the volcano lying beneath the waters may be reawakening after generations of dormancy.

As underwater work continues to reveal the magnificence of the ancient Roman villa's mosaic floor, scientists and archaeologists are reminded of the fragile balance between preservation and the potential threat posed by the active volcanoes in the area.
