So the Parthian Empire doesn't count? What of the Indian subcontinent and all of Asia (which were known)? What of the African coasts (which were known)? What opf the Celtic Barbarians?

"All the World", in those days, was the Roman Empire:
"And it came to pass in those days, that there went out a decree from Caesar Augustus that all the world should be taxed." (Luke 2:1 KJV)
"And there stood up one of them named Agabus, and signified by the Spirit that there should be great dearth throughout all the world: which came to pass in the days of Claudius Caesar." (Acts 11:28 KJV)
"So that not only this our craft is in danger to be set at nought; but also that the temple of the great goddess Diana should be despised, and her magnificence should be destroyed, whom all Asia and the world worshippeth." (Acts 19:27 KJV)
"First, I thank my God through Jesus Christ for you all, that your faith is spoken of throughout the whole world." (Rom 1:8 KJV)
