rippling, moire-like effect.

However, when Marie and Pierre turned their eyes to the west, they were
quite dazzled. The sun rays were here streaming on the large and the
little Beout with their cupolas of unequal height. And on this side the
background was one of gold and purple, a dazzling mountain on whose sides
one could only discern the road which snaked between the trees on its way
to the Calvary above. And here, too, against the sunlit background,
radiant like an aureola, stood out the three superposed churches which at

Blessed Virgin. First of all, down below, came the church of the Rosary,
squat, circular, and half cut out of the rock, at the farther end of an
esplanade on either side of which, like two huge arms, were colossal

expended here, a quarryful of stones had been cut and set in position,
there were arches as lofty as naves supporting the gigantic terraced
avenues which had been constructed so that the processions might roll
along in all their pomp, and the little conveyances containing sick
children might ascend without hindrance to the divine presence. Then came

dense greenery of the Calvary hill, it looked fragile and candid, like
