In this period, more than any other before or after—until the 20th century—a sizable part of the population lived outside the walls, but we have no means of assessing the number of extramural population. Our rather high estimate is corroborated by the lists of the Christians that were killed or taken prisoner during the Persian invasion in 614 A.D. Unfortunately, those lists, preserved in several languages and several versions suffer from copyists’ and translators’ errors and cannot provide definite numbers. Cf. J. T. Milik, “La tophographie de Jerusalem vers la fin de l’epoque Byzantine”, Melanges de l’universite St. Joseph 37 (1961), p. 133.
