I looked round, with a chill of fear in my heart, at the huge swelling plain, mottled with the green patches of rushes. Nothing stirred over the vast expanse save a pair of ravens, which croaked loudly from a tor behind us.

One perched, Celaeno, on a rock, and lo, / thus croaked the dismal seer her prophecy of woe. / "War, too, Laomedon's twice-perjured race! / War do ye bring, our cattle stol'n and slain? / And unoffending Harpies would ye chase / forth from their old, hereditary reign?"
