    “The wind’s on the wold
    And the night is a-cold,
    And Thames runs chill
    ‘Twixt mead and hill.
    But kind and dear
    Is the old house here
    And my heart is warm
    Midst winter’s harm.”
    —William Morris (1834–1896)

    “O heart the winds have shaken, the unappeasable host
    Is comelier than candles at Mother Mary’s feet.”
    —William Butler Yeats (1865–1939)

    “Fasten your hair with a golden pin,
    And bind up every wandering tress;
    I bade my heart build these poor rhymes:
    It worked at them, day out, day in,
    Building a sorrowful loveliness
    Out of the battles of old times.”
    —William Butler Yeats (1865–1939)
