“[A cave] that trembled with the roaring of the deep.”

“He ceased; but still their trembling ears retained
The deep vibrations of his witching song.”

“People’s lives, in Jubilee as elsewhere, were dull, simple, amazing, and unfathomable – deep caves paved with kitchen linoleum.”

“Go, view the settling sea: the stormy wind is laid. The billows still tremble on the deep. They seem to fear the blast.”

“And then more quiet, silence so deep it almost drowned out the roar of the night music that pounded away in my secret self.”

“Leroi-Gourhan surveyed more than sixty caves and saw order in the distribution of their images. Deer… often appeared in entranceways but were uncommon in main chambers. Horse, bison, and ox were the predominant creatures of the main chambers. Carnivores mostly occurred deep in the cave system.”

“… the proliferation of luminous fungi or iridescent crystals in deep caves where the torchlessly improvident hero needs to see is one of the most obvious intrusions of narrative causality into the physical universe.”

“There is a pleasure in the pathless woods,
There is a rapture on the lonely shore,
There is society, where none intrudes,
By the deep sea, and music in its roar:
I love not man the less, but Nature more”

“Twixt devil and deep sea, man hacks his caves;
Birth, death; one, many; what is true, and seems;
Earth's vast hot iron, cold space's empty waves.”

“What is a cave? A cave is a shape. It’s not the lump of mountain over it.”
