Level 1 — Absolute Beginner
A ship sank near Greece a very long time ago. It sank near an island called Kefalonia.
The ship was carrying many clay jars. The jars are called amphorae. There were about 6,000 of them.
The ship has been under the sea for about 2,000 years. Scientists found it using sonar.
This is one of the biggest old shipwrecks ever found in that part of the sea.

Level 2 — Elementary
Researchers studying the seafloor near Kefalonia, a Greek island in the Ionian Sea, have discovered a massive Roman era shipwreck still loaded with roughly 6,000 amphorae, the clay jars ancient traders used to carry goods like wine and olive oil.
The ship has rested on the seabed for about 2,000 years near the coast of Fiscardo, a small port town on the island.
A university research team, using sonar equipment and artificial intelligence to scan the seafloor, spotted the outline of the wreck at a depth of around 60 meters.
Experts say it ranks among the largest Roman shipwrecks ever recorded in the eastern Mediterranean Sea, offering new clues about ancient trade routes.

Level 3 — Intermediate
A team from the University of Patras has identified a Roman era merchant vessel resting off the coast of Kefalonia, an island in Greece's Ionian Sea, still bearing an estimated 6,000 amphorae after roughly two millennia beneath the waves.
The wreck, located near the port of Fiscardo at a depth of about 60 meters, measures approximately 34 meters long and 12 meters wide, making it, by cargo volume, one of the largest Roman shipwrecks documented anywhere in the eastern Mediterranean.
Researchers credit the discovery to a survey method combining sonar imaging with machine learning software trained to automatically recognize the telltale shapes of amphora cargoes scattered across the seafloor.
Because amphorae were the standard shipping containers of antiquity, the wreck's sheer scale offers archaeologists a rare, densely packed snapshot of the commercial networks that connected Roman era ports across the Mediterranean.

Level 4 — Advanced
A survey team from the University of Patras's Oceanus network has identified a Roman era merchant vessel off Kefalonia in Greece's Ionian Sea, its hull still cradling an estimated 6,000 amphorae after nearly two millennia submerged, a discovery now ranked among the largest of its kind ever documented in the eastern Mediterranean.
Resting at roughly 60 meters near the port of Fiscardo and measuring approximately 34 by 12 meters, the vessel's dimensions and cargo density place it in rare company among Roman wrecks, offering a comparatively intact archive of the amphora borne trade that once knitted together Mediterranean ports.
The find was made possible not by chance but by a systematic survey methodology pairing multibeam sonar with machine learning classifiers trained to flag the characteristic acoustic signatures of amphora fields strewn across the seabed, a technique that is steadily reshaping how underwater archaeologists prioritize which anomalies merit a diver's attention.
Because amphorae functioned as antiquity's standardized shipping containers, their sheer density here transforms what might otherwise be an isolated find into a proxy for the scale and routing of Roman commerce, inviting comparisons with other well documented wrecks and refining scholars' models of how goods, and by extension wealth, moved across the ancient sea.
