Long-distance timber trade underpinned the Roman Empire's construction-The Archeology News Network

Mauro Bernabée, a researcher working at the National Research Council in Italy, is an open access peer-reviewed scientific journalPLOS ONEThe paper was published above, revealing that wood was transported over long distances during the Roman Empire.

There are many kinds of wood used in ancient Roman buildings and ships, and it is thought that timber was collected from various places around the Roman Empire and used as fuel for construction, shipbuilding and even fuel. Bernabay et al.'S research team investigated 24 very well preserved oak materials that were considered to be ancient Roman timber. The surveyed oak wood was excavated during the construction of the subway in Rome from 2014 to 2016.

The red frame in the map below is where the oak was surveyed.

The oak used for the survey is in the Italian capital of Rome.Sannio StreetIt is presumed to be part of a colonnade in the garden of a mansion that once existed. It seems to have been buried in the ground in the following form.

The following is a photograph of a part of a colonnade excavated from the ground.

Berna Bay succeeded in dating 13 out of 24 by measuring the annual ring width of each oak and predicting the approximate age by conducting statistical tests. Furthermore, by comparing the dating results with the reference ages of oak wood in the Mediterranean and Central Europe, we analyzed where the oak wood under investigation was harvested.Jura MountainsIt has become clear that it was collected nearby. In addition, of the 13 oaks that were successfully dated, 8 were found to have been harvested between 40 and 60 AD.

From the size of the oak used in the colonnade and the transport distance of 1,700 km, Bernabay said, “Ancient Romans (or merchants who traded with ancient Romans) floated wood on the water,Saone RiverWhenRhone RiverFrom the Mediterranean SeaTiberI guess I was transporting timber to Rome. "

The following red circle is the point where oak is estimated to have been cut down. From there, it is believed that they traveled down the Saône and Rhone rivers in the blue line to the Mediterranean and transported timber to Rome.

Berna Bay speculated that the logistics organization in ancient Rome was of a considerable level due to the difficulty of obtaining oak planks. Furthermore, the fact that long-distance transportation of 1700 km was carried out suggests that trade was carried out frequently in various regions during the Roman period.

Bernabay said, “This study shows that during ancient Roman times, timber was transported for construction purposes from the natural forest area in northeastern France to the center of Rome. From the many obstacles that can occur, we can see that the ancient Romans and their societies had a powerful transport organization, and that timber was very important to ancient Rome.
