疯狂山脉（VIII）(6)

This river, once crossed by scores of noble stone bridges, was plainly the one whose extinct course we had seen in our aëroplane survey. Its position in different carvings of the city helped us to orient ourselves to the scene as it had been at various stages of the region’s age-long, aeon-dead history; so that we were able to sketch a hasty but careful map of the salient features—squares, important buildings, and the like—for guidance in further explorations. We could soon reconstruct in fancy the whole stupendous thing as it was a million or ten million or fifty million years ago, for the sculptures told us exactly what the buildings and mountains and squares and suburbs and landscape setting and luxuriant Tertiary vegetation had looked like. It must have had a marvellous and mystic beauty, and as I thought of it I almost forgot the clammy sense of sinister oppression with which the city’s inhuman age and massiveness and deadness and remoteness and glacial twilight had choked and weighed on my spirit. Yet according to certain carvings the denizens of that city had themselves known the clutch of oppressive terror; for there was a sombre and recurrent type of scene in which the Old Ones were shewn in the act of recoiling affrightedly from some object—never allowed to appear in the design—found in the great river and indicated as having been washed down through waving, vine-draped cycad-forests from those horrible westward mountains.
