It was the cooling hour, just when the rounded
  Red sun sinks down behind the azure hill,
    Which then seems as if the whole earth is bounded,
      Circling all nature, hush'd, and dim, and still,
        With the far mountain-crescent half surrounded
          On one side, and the deep sea calm and chill
            Upon the other, and the rosy sky
              With one star sparkling through it like an eye.
 — Lord Byron (George Gordon Noel Byron)
