At the very last I thought I saw signs of an artistic anticlimax. The paintings were less skilful, and much more bizarre than even the wildest of the earlier scenes. They seemed to record a slow decadence of the ancient stock, coupled with a growing ferocity toward the outside world from which it was driven by the desert. The forms of the people—always represented by the sacred reptiles—appeared to be gradually wasting away, though their spirits as shown hovering above the ruins by moonlight gained in proportion. Emaciated priests, displayed as reptiles in ornate robes, cursed the upper air and all who breathed it; and one terrible final scene showed a primitive-looking man, perhaps a pioneer of ancient Irem, the City of Pillars, torn to pieces by members of the older race. I remembered how the Arabs fear the nameless city, and was glad that beyond this place the gray walls and ceiling were bare.
