Famous quotes containing the word clay:

    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)

    Water. Its sunny track in the plain; its splashing in the garden canal, the sound it makes when in its course it meets the mane of the grass; the diluted reflection of the sky together with the fleeting sight of the reeds; the Negresses fill their dripping gourds and their red clay containers; the song of the washerwomen; the gorged fields the tall crops ripening.
    Jacques Roumain (1907–1945)

    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)
