The sites in and round the Temple enclosure, and that of St. Stephen’s death, with some on Olivet, were equally liable to change in course of time. Thus the Pool of Bethesda has been traditionally pointed out in three separate places. From 333 A. D. down to 440 A. D. the “Sheep Pool,” or Bethesda, is placed at the “Twin Pools,” which still exist in the Antonia fosse,[26] and which may have been cut out of the rock in the time of Herod or later. They are vaulted over with masonry, probably of the sixth century A. D., and gradually disappeared from sight as the level of the street was raised above them; thus already in the sixth century the “Sheep Pool” is placed at some distance from the “House of Pilate,” which immediately adjoined the “Twin Pools.”[27] In the twelfth century Bethesda is always described as being at the “Piscina Interior,” or “inner pool,” a large rock tank west of the Church of St. Anne, which was rediscovered in 1888; but even in the thirteenth century the Templars were showing another site, namely, that which appears on the old map of Jerusalem (about 1308 A. D.), and which is the same now pointed out--the Birket Isrâîl, or “Pool of Israel.”[28] There was considerable difference of opinion also as to where the Prætorium, or “House of Pilate,” should be placed. In the sixth century it was at the Antonia site, where Justinian built a chapel of St. Sophia--now the “Chapel of the Mocking”--inside the Turkish barracks. In the seventh and early in the twelfth centuries it was supposed to be on Mount Sion, but in the thirteenth it was replaced at the north-west corner of the Ḥaram.[29]
