Below is conclusive evidence Dr. David Livingston was wrong in his milestone measurements:
Please ignore all my placemarks north of Jebel et-Tawil-they are over a year old and are in serious need of updating. Also, Tell el-Ful is not necessarily Gibeah. I have re-arranged Livingston’s map in several different ways, and it is clear that from his 5th milestone (which is placed by him 200 or so yards too far south, judging by the Survey of Western Palestine’s map) to his 11th milestone, a Roman mile of 1400 or so yards is used by Livingston. This is consistent with my observations in October 2011 and March 2011. Needless to say, the Roman mile was some 1614-1618 yards in length, and there is no warrant to shortening it to 1400 or so yards merely to get the result one desires. Besides, even if Livingston was correct regarding his milestone measurements, Bireh would still only be 11, not 12 milestones from Jerusalem.
