Famous quotes containing the word clay:
“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)
“Archaeologists have uncovered six-thousand-year-old clay tablets from southern Babylonia that describe in great detail how the adults of that community found the younger generation to be insolent and disobedient.”
—Lawrence Kutner (20th century)
“The earth is covered thick with other clay,
Which her own clay shall cover, heaped and pent,
Rider and horse,—friend, foe,—in one red
burial blent!”
—George Gordon Noel Byron (1788–1824)
