The first thing I noticed were the three roofs of the _piscines_, on the left side of the road, built under the cliff on which the churches stand. I shall have more to say of them presently, but now it is enough to remark that they resemble three little chapels, joined in one, each with its own doorway; an open paved space lies across the entrances, where the doctors and the priests attend upon the sick. This open space is fenced in all about, to keep out the crowd that perpetually seethes there. We went a few steps farther, worked our way in among the people, and fell on our knees. Overhead, the cliff towered up, bare hanging rock beneath, grass and soaring trees above; and at the foot of the cliff a tall, irregular cave. There are two openings of this cave; the one, the larger, is like a cage of railings, with the gleam of an altar in the gloom beyond, a hundred burning candles, and sheaves and stacks of crutches clinging to the broken roofs of rock; the other, and smaller, and that farther from us, is an opening in the cliff, shaped somewhat like a _vesica_. The grass still grows there, with ferns and the famous climbing shrub; and within the entrance, framed in it, stands Mary, in white and blue, as she stood fifty years ago, raised perhaps twenty feet above the ground. Ah, that image!... I said, "As she stood there!" Yet it could not have been so; for surely even simple Bernadette would not have fallen on her knees. It is too white, it is too blue; it is, like the three churches, placed magnificently, yet not impressive; fine and slender, yet not graceful. But we knelt there without unreality, with the river running swift behind us; for we knelt where a holy child had once knelt before a radiant vision, and with even more reason; for even if the one, as some say, had been an hallucination, were those sick folk an hallucination? Was Pierre de Rudder's mended leg an hallucination, or the healed wounds of Marie Borel? Or were those hundreds upon hundreds of disused crutches an illusion? Did subjectivity create all these? If so, what greater miracle can be demanded?
