The concept is related to or derived from the better-known Hollow Earth theory, and was an infrequent but recurring plot device in pre-spaceflight science fiction.

Famous quotes containing the words hollow and/or moon:
“Darker grows the valley, more and more forgetting:
So were it with me if forgetting could be willed.
Tell the grassy hollow that holds the bubbling well-spring
Tell it to forget the source that keeps it filled.”
—George Meredith (1828–1909)
“It was the most wild and desolate region we had camped in, where, if anywhere, one might expect to meet with befitting inhabitants, but I heard only the squeak of a nighthawk flitting over. The moon in her first quarter, in the fore part of the night, setting over the bare rocky hills garnished with tall, charred, and hollow stumps or shells of trees, served to reveal the desolation.”
—Henry David Thoreau (1817–1862)
