Famous quotes containing the words hollow and/or moon:
“Having books published is very destructive to writing. It is even worse than making love too much. Because when you make love too much at least you get a damned clarte that is like no other light. A very clear and hollow light.”
—Ernest Hemingway (1899–1961)
“The moon shines bright. In such a night as this,
When the sweet wind did gently kiss the trees,
And they did make no noise, in such a night
Troilus methinks mounted the Troyan walls,
And sighed his soul toward the Grecian tents,
Where Cressid lay that night.”
—William Shakespeare (1564–1616)
