Famous quotes containing the word roof:

    Nothing aids which may not also injure us.
    Fire serves us well, but he who plots to burn
    His neighbor’s roof arms his hands with fire.
    Ovid (Publius Ovidius Naso)

    The poorest man may in his cottage bid defiance to all the forces of the Crown. It may be frail—its roof may shake—the wind may blow through it—the storm may enter—the rain may enter—but the King of England cannot enter!—all his forces dare not cross the threshold of the ruined tenement!
    William Pitt, The Elder, Lord Chatham (1708–1778)

    The far-off clinching and mating of arches, the leap and thrust of the stone, carrying a great roof overhead, awed and silenced her.
    —D.H. (David Herbert)
