Dr Campbell is co-director of the Fourni survey project of the US-based RPM Nautical Foundation, a non-profit organisation involved in several Mediterranean underwater projects. The Fourni survey project began in 2015.

The shipwrecks, all trading ships, were found off Fourni island and its surrounding islets. Fourni is made up of 20 small islands, islets and reefs.

The recent discoveries make up 58 shipwrecks found in what archaeologists said may be the largest concentration of ancient wrecks ever found in the Aegean and possibly the entire Mediterranean, according to Reuters.

“I would call it, probably, one of the top archaeological discoveries of the century in that we now have a new story to tell of a navigational route that connected the ancient Mediterranean,” Dr Campbell told the wire service.

The older wrecks date to the 4th and 2nd centuries BC and the 5th-6th centuries AD, while the more recent ones are from the 18th or 19th century, said archaeologist George Koutsouflakis, joint leader of the project.

“It is not a coincidence that a large number of the wrecks have been found in those passages,” he said.

“If there is a sudden change in the wind’s direction, and if the captain was from another area and was not familiar with the peculiarities of the local climate, he could easily end up losing control of the ship and falling upon the rocks.”

Divers also recovered a group of 2nd century AD terracotta lamps, bearing the names of the Corinthian artisans who made them, Octavius and Lucius, in addition to the cargoes of amphorae jars which contained wine, oil and foodstuffs.

They may have been slave workers who later gained their freedom and set up their own pottery workshops, a Greek Culture Ministry statement said.

The project is planned to continue over the next five years.
