Famous quotes containing the word clay:
“Protoplasm, simple or nucleated, is the formal basis of all life. It is the clay of the potter: which, bake it and paint it as he will, remains clay, separated by artifice, and not by nature from the commonest brick or sun-dried clod.”
—Thomas Henry Huxley (1825–1895)
“With earth’s first clay they did the last man knead,
There of the last harvest sowed the seed,
And what the first morning of creation wrote,
The last dawn of reckoning shall read.”
—Edward Fitzgerald (1809–1883)
“When Nature was shaping him, clay was not granted
For making so full-sized a man as she wanted,
So, to fill out her model, a little she spared
From some finer-grained stuff for a woman prepared,
And she could not have hit a more excellent plan
For making him fully and perfectly man.”
—James Russell Lowell (1819–1891)
