Famous quotes containing the words fire and/or clay:
“When there was no more lantern in the kitchen,
The fire got out through crannies in the stove
And danced in yellow wrigglers on the ceiling,
As much at home as if they’d always danced there.”
—Robert Frost (1874–1963)
“I am sure my bones would not rest in an English grave, or my clay mix with the earth of that country. I believe the thought would drive me mad on my death-bed could I suppose that any of my friends would be base enough to convey my carcass back to her soil. I would not even feed her worms if I could help it.”
—George Gordon Noel Byron (1788–1824)
