Famous quotes containing the word clay:
“And here the precious dust is layd;
Whose purely temper’d Clay was made
So fine, that it the guest betray’d.
Else the soule grew so fast within,
It broke the outward shell of sinne,
And so was hatch’d a Cherubin.”
—Thomas Carew (1589–1639)
“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)
“You may melt your metals and cast them into the most beautiful moulds you can; they will never excite me like the forms which this molten earth flows out into. And not only it, but the institutions upon it are plastic like clay in the hands of the potter.”
—Henry David Thoreau (1817–1862)
