Famous quotes containing the words thread and/or form:

    “Deep in the sun-searched growths the dragonfly
    Hangs like a blue thread loosened from the sky—
    So this winged hour is dropped to us from above.
    Oh! clasp we to our hearts, for deathless dower,
    This close-companioned inarticulate hour
    When twofold silence was the song of love.”
    —Dante Gabriel Rossetti (1828–1882)

    “Others form man; I tell of him, and portray a particular one, very ill-formed, whom I should really make very different from what he is if I had to fashion him over again. But now it is done.”
    —Michel de Montaigne (1533–1592)
