Opening quote: "Home is the sailor.....-Fragment of Ancient Earth Text". 1894, Robert Louis Stevenson's gravestone epitaph: "Under the wide and starry sky, Dig the grave and let me lie. Glad did I live and gladly die, And I laid me down with a will. This be the verse you grave for me: "Here he lies where he longed to be. Home is the sailor, home from the sea, And the hunter home from the hill".
