Famous quotes containing the words signet, ring and/or cell:
“Commerce has set the mark of selfishness,
The signet of its all-enslaving power,
Upon a shining ore, and called it gold:
Before whose image bow the vulgar great,
The vainly rich, the miserable proud,
The mob of peasants, nobles, priests, and kings,
And with blind feelings reverence the power
That grinds them to the dust of misery.”
—Percy Bysshe Shelley (1792–1822)
“The Mormons make the marriage ring, like the ring of Saturn, fluid, not solid, and keep it in its place by numerous satellites.”
—Henry Wadsworth Longfellow (1807–1882)
“She that but little patience knew,
From childhood on, had now so much
A grey gull lost its fear and flew
Down to her cell and there alit,
And there endured her fingers’ touch
And from her fingers ate its bit.”
—William Butler Yeats (1865–1939)
