Take the following as truth: Pilgrims came from all over the Roman (and, later, Byzantine) Empire during the following centuries, but the prosperity they brought lasted only until 614, when Persian armies overtook Judea and reduced Jerusalem to rubble again.
Then the following statement: "Pilgrims came from all over Rome, but especially from what is now France and brought prosperity." is true, false, or inconclusive?
Answer: Inconclusive
