(Chinese) Yu Huan, description of Romans, Weilue or Brief History of the Wei (excerpts), 265 CE
NOTE: Weilue, or the brief history of the Wei, was written by Yu Huan. Wei or Cao Wei was one of three states in that vied for power in the Three States Period of Chinese dynastic history (220-280 CE). In this passage Yu Huan draws on several sources to describe Romans.
This country (the Roman Empire) has more than four hundred smaller cities and towns. It extends several thousand li in all directions. The king has his capital (that is, the city of Rome) close to the mouth of a river (the Tiber). The outer walls of the city are made of stone.
…The ruler of this country is not permanent. When disasters result from unusual phenomena, they unceremoniously replace him, installing a virtuous man as king, and release the old king, who does not dare show resentment.
The common people are tall and virtuous like the Chinese, but wear hu ('Western') clothes. They say they originally came from China, but left it.
They have always wanted to communicate with China but, Anxi (Parthia), jealous of their profits, would not allow them to pass (through to China).
