Famous quotes containing the word hid:
“For precious friends hid in death’s dateless night.”
—William Shakespeare (1564–1616)
“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)
“Consider what you have in the smallest chosen library. A company of the wisest and wittiest men that could be picked out of all civil countries in a thousand years have set in best order the results of their learning and wisdom. The men themselves were hid and inaccessible, solitary, impatient of interruption, fenced by etiquette; but the thought which they did not uncover in their bosom friend is here written out in transparent words to us, the strangers of another age.”
—Ralph Waldo Emerson (1803–1882)
