Following the road southward along the Kidron we arrive at the Fountain of the Virgin, on the west bank of the torrent. This is highly esteemed by both Christians and Mohammedans, who believe (according to an ancient tradition) that the Virgin Mary used to frequent it to draw water and wash the clothes of her Divine Son. The latter have an oratory, where, after ablutions in the fountain, they offer up their prayers to the mother of Isa (Jesus). A small mosque stood here in the sixteenth and seventeenth century, but even its ruins have now disappeared. The Arabs call the place _Aïn Sitti Mariam_ (Fountain of our Lady Mary), and also _Aïn um-el-Deraj_ (Fountain of our Lady near the steps). It is at the extremity of an excavation in the rock, reached by 28 steps, which, as I have already said[621], have been constructed owing to the rise of the ground. These are divided into two flights by a chamber with a pointed vaulting (Crusaders' work), which is 9-1/2 feet wide and 10-1/4 high. The lower grotto is 26 feet deep, the water flows into a basin 16 feet long, 6 wide, and 7 deep; and from this to the upper pool of Siloam through a subterranean conduit. I shall consider this conduit and the intermittent flow of the fountain in the chapter on the waters. Popular superstition attributes the interruption of the stream to a dragon, that lives concealed at the source, and arrests its course in quenching his thirst. It is also commonly believed that the water is supplied by reservoirs under the _Haram_, which is not far from the truth, as we shall see. On our way from the fountain to the Pool of Siloam we follow the bed of the torrent for a little way, and then take the road skirting the western bank of the valley. This leads us to a small pond adjoining the western corner of the pool situated almost at the south extremity of Ophel, at the end of the Tyropoeon Valley. This pool is frequently mentioned in the Scriptures. Isaiah speaks of its 'waters that go softly[622];' Nehemiah[623], of the wall of the Pool of Siloam; S. John[624], of the man born blind, who was sent to 'wash in the Pool of Siloam.' Josephus frequently names it, especially in one of his addresses to the besieged Jews, when he tells them, as a sign of God's anger, that the Fountain of Siloam, which before the siege had ceased to supply them with water, now gave forth plenty to the Romans. He tells them also that the same thing took place during the siege by Nebuchadnezzar[625]. On the last day of the Feast of Tabernacles the people went with great solemnity to draw the water of Siloam, and brought it to the altar, where it was mingled with the wine of the sacrifices; in remembrance of the water which God had given them in the desert by the rod of Moses, and to entreat Him to send down rain on the new-sown seed. At this festival our Lord was present when he cried, "If any man thirst, let him come unto Me and drink[626]." The Talmud[627]
