Famous quotes containing the word hid:
“But the golden-rod is one of the fairy, magical flowers; it grows not up to seek human love amid the light of day, but to mark to the discerning what wealth lies hid in the secret caves of earth.”
—Margaret Fuller (1810–1850)
“A pity beyond all telling
Is hid in the heart of love.”
—William Butler Yeats (1865–1939)
“I had gone so long without loving
I hardly knew what I was thinking.
Where I hid my face, your touch, quick, merciful
Blindfolded me. A god breathed from my lips.
If that was illusion, I wanted it to last long;”
—James Merrill (b. 1926)
