XII.
Danforth and I have recollections of emerging into the great sculptured hemisphere and of threading our back trail through the Cyclopean rooms and corridors of the dead city; yet these are purely dream fragments involving no memory of volition, details, or physical exertion.
There was something vaguely appropriate about our departure from those buried epochs; for as we wound our panting way up the sixty-foot cylinder of primal masonry we glimpsed beside us a continuous procession of heroic sculptures in the dead race's early and undecayed technique—a farewell from the Old Ones, written fifty million years ago.
Finally, scrambling out at the top, we found ourselves on a great mound of tumbled blocks, with the curved walls of higher stonework rising westward, and the brooding peaks of the great mountains showing beyond the more crumbled structures toward the east.
The sky above was a churning and opalescent mass of tenuous ice vapors, and the cold clutched at our vitals.
In less than a quarter of an hour we had found the steep grade to the foothills—the probable ancient terrace—by which we had descended, and could see the dark bulk of our great plane amidst the sparse ruins on the rising slope ahead.
Halfway uphill toward our goal we paused for a momentary breathing spell, and turned to look again at the fantastic tangle of incredible stone shapes below us—once more outlined mystically against an unknown west. As we did so we saw that the sky beyond had lost its morning haziness; the restless ice vapors having moved up to the zenith, where their mocking outlines seemed on the point of settling into some bizarre pattern which they feared to make quite definite or conclusive.
There now lay revealed on the ultimate white horizon behind the grotesque city a dim, elfin line of pinnacled violet whose needle-pointed heights loomed dreamlike against the beckoning rose color of the western sky. Up toward this shimmering rim sloped the ancient table-land, the depressed course of the bygone river traversing it as an irregular ribbon of shadow.
