Famous quotes containing the words hollow moon, hollow and/or 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)
“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)
“Would you hear of an old-time sea-fight?
Would you learn who won by the light of the moon and stars?
List to the yarn, as my grandmother’s father the sailor told it to
me.”
—Walt Whitman (1819–1892)
