When we reached the top, we sat down on a pile of rocks, and looked back over the plain to the sacred mountains, which we knew we should never see again. From this time we could no longer get a view even on the distant horizon, but we had hoped this morning, as the sun rose, we might have vouchsafed to us one more last look.
