A Subterranean City
I followed once a fleet and mighty serpent
Into a cavern in a mountain’s side;
And, wading many lakes, descending gulphs,
At last I reached the ruins of a city,
Built not like ours but of another world,
As if the aged earth had loved in youth
The mightiest city of a perished planet,
And kept the image of it in her heart,
So dream-like, shadowy, and spectral was it.
Nought seemed alive there, and the bony dead
Were of another world the skeletons.
The mammoth, ribbed like to an arched cathedral,
Lay there, and ruins of great creatures else
More like a shipwrecked fleet, too vast they seemed
For all the life that is to animate:
And vegetable rocks, tall sculptured palms,
Pines grown, not hewn, in stone; and giant ferns,
Whose earthquake-shaken leaves bore graves for nests.
