Another great article, thanks.

It's amazing that they found this with seabed sonar scans and you can see the cluster of amphorae so clearly. It's astonishing that the cargo would remain so tightly clustered together in only 197 feet of water for so long.

I always thought amphorae were used to transport liquid cargo (oil, wine). The article says they may have carried wine, olive oil, nuts, wheat or barley.

The article got me thinking about Roman merchant ships, propulsion, life on board and what it must have been like to survive (or die) in a gale in the Med and a shipwreck. The "World History Encyclopedia" site has an article on Roman Shipbuilding & Navigation. Here are a couple of interesting passages...

The Romans were not traditionally sailors but mostly land-based people who learned to build ships from the people that they conquered, namely the Carthaginians (and their Phoenician predecessors), the Greeks and the Egyptians. There are a few surviving written documents that provide descriptions and representations of ancient Roman ships concerning the masts, sails and rigging.

Merchant ships were built to transport lots of cargo over long distances and at a reasonable cost, therefore speed and maneuverability were not a priority. They had a length to breadth ratio of the underwater hull of about 3:1 (6:1 or 7:1 for warships), double planking and a ballast for added stability. Unlike warships, their V-shaped hull was deep underwater meaning that they could not sail too close to the coast. They usually had two huge side rudders (or steering oars) located off the stern and controlled by a small tiller bar connected to a system of cables. They had from one to three masts with large square sails and a small triangular sail called the supparum at the bow.

The Roman merchant ship's cargo capacity usually was between 100 to 150 tons (150 tons being the capacity of a ship carrying 3,000 amphorae). The smallest ships had a capacity of 70 tons while the largest could have a capacity of 600 tons for a length of 150 feet. Cargo included agricultural goods (e.g. grain from Egypt's Nile valley, wine, oil, etc.), raw materials (iron bars, copper, lead ingots, marble, and granite) and other goods. Just like warships, merchant ships also used oarsmen.

Following the collapse of the Roman Empire, no ships of the cargo-carrying capacity of Roman ships were built until the 16th century AD.

How do you suppose trade was conducted? Were written orders carried by ships to other ports? Were empty ships plying the waters making opportunistic stops hoping to pick up cargo? Were some ships just going back and forth between Port A and Port B carrying the same cargos all the time? It's hard to imagine this without modern electronic communications. Of course, it was all written orders until the advent of radio only a hundred years ago.

An important consideration was that the Romans cleared the Med of pirates for a long time, making larger and slower moving vessels profitable. With no cannon, such vessels are sitting ducks for pirates. The largest ships would have been built for specialized trade such as hauling grain or oil and a few for carrying prefabricated columns of immense weight like the Egyptian granite columns used at the Pantheon.

Those were cut as single pieces about 100 miles east of the Nile, transported to the river somehow, floated on barges to Alexandria and then shipped to Ostia, barged again up the Tiber and trundled to the Pantheon. Each column weighs 60 tons.

A lot of the archival scholarship on Roman maritime history was written by ninnies. :^) The Romans moved large stone objects from Egypt by sea. They were so large, that had they tried to move them by land, they’d still be working on it.

I particularly like “meaning that they could not sail too close to the coast” — the best preserved ancient wrecks are probably down on the abyssal plain, but most ships that foundered hit reefs or rocks which are disproportionately found near the coast. The dolts who write, “ancient sailors hugged the coastline” just simply don’t know what they’re talking about.

Thanks for that excerpt, it’s great. :^)
