Saturn

Saturn, whose name in the heavens is Lurga, stood in the Blue Room. His spirit lay upon the house, or even on the whole Earth, with a cold pressure such as might flatten the very orb of Tellus to a wafer. Matched against the lead-like burden of his antiquity the other gods themselves perhaps felt young and ephemeral. It was a mountain of centuries sloping up from the highest antiquity we can conceive, up and up like a mountain whose summit never comes into sight, not to eternity where the thought can rest, but into more and still more time, into freezing wastes and silence of unnameable numbers. It was also strong like a mountain; its age was no mere morass of time where imagination can sink in reverie, but a living, self-remembering duration which repelled lighter intelligences from its structure as granite flings back waves, itself unwithered and undecayed but able to wither any who approach it unadvised...
