We tend to think of Roman architecture as monuments and buildings of stone, but that is because stone is more likely to survive. Roman wooden architecture is rarely found these days, but it was the material of choice, especially in Northwestern Europe. Wood was also essential for ship building, and here the Romans were masters of that material.
Did they miss that the Romans were also harvesting and transporting the Cedars of Lebanon?
It should be noted that the wealth, splendor and achievements such as distant timber harvesting and transport was the product of a capitalist system and the respect for private property rights in Roman law.
I’m always astonished at the range and diversity of trade in the ancient world. There have been some amazing finds in the Americas, too: goods that traveled almost unbelievable distances, trade among civilizations most people never hear about.
