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)

    Who among us has not, in moments of ambition, dreamt of the miracle of a form of poetic prose, musical but without rhythm and rhyme, both supple and staccato enough to adapt itself to the lyrical movements of our souls, the undulating movements of our reveries, and the convulsive movements of our consciences? This obsessive ideal springs above all from frequent contact with enormous cities, from the junction of their innumerable connections.
    Charles Baudelaire (1821–1867)
