Famous quotes containing the words thread and/or form:

    “It may be the more
    That no line of her writing have I,
    Nor a thread of her hair,
    No mark of her late time as dame in her dwelling, whereby
    I may picture her there.”
    —Thomas Hardy (1840–1928)

    “I wage not any feud with Death
    For changes wrought on form and face;
    No lower life that earth’s embrace
    May breed with him can fright my faith.”
    —Alfred Tennyson (1809–1892)
