Trajan's Column is a Roman triumphal column in Rome, Italy, that commemorates Roman emperor Trajan's victory in the Dacian Wars. It was probably constructed under the supervision of the architect Apollodorus of Damascus at the order of the Roman Senate.
Palmyra and the Silk Road in the early Middle Ages
The ancient caravan city of Palmyra was a Roman provincial capital, which was an important trade centre on the Silk Road strategically situated between east and west connecting the Chinese, Persian and Roman empires. Merchants coming to or returning from Rome had to stop in Palmyra to pay taxes and simply to rest. Since around the year 227 AD, however, trade had been halted at intervals by the Sassanid Persians who periodically blocked the route to exact tribute. Silk had bee among the most popular commodities in Rome from before the time of Augustus (27 BC-14AD).
