Full many a gem of purest ray serene,
The dark unfathomed caves of ocean bear:
Full many a flower is born to blush unseen,
And waste its sweetness on the desert air.
- Thomas Gray, "Elegy Written in a Country Churchyard" (14th stanza), in Mary Ferguson, Mary Jo Salter & Jon Stallworthy, eds., The Norton Anthology of Poetry: Shorter Fourth Edition (New York: W.W. Norton & Company, Inc., 1997), p. 367.
