Today we rode for hours while the perspectives grew greater and more magnificent in ordered design, till a gap in the cliff face opened on our right to a new wonder. The gap, perhaps three hundred yards across, was a crevice in such a wall; and led to an amphitheatre, oval in shape, shallow in front, and long-lobed right and left. The walls were precipices, like all the walls of Rumm; but appeared greater, for the pit lay in the very heart of a ruling hill, and its smallness made the besetting heights seem overpowering.
