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 related to hollow moon:
“I had a thought for no one’s but your ears:
That you were beautiful, and that I strove
To love you in the old high way of love;
That it had all seemed happy, and yet we’d grown
As weary-hearted as that hollow moon.”
—William Butler Yeats (1865–1939)
