Famous quotes containing the words cloud and/or base:
“O months of blossoming, months of transfigurations,
May without cloud and June stabbed to the heart,
I shall not ever forget the lilacs or the roses
Nor those the spring has kept folded away apart.”
—Louis Aragon (1897–1982)
“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)
