Turns her impatient head from side to side
In universal terrors—all too wide
To watch; and often to that marble keep
Upturns her pearly eyes, as if she spied
Some foe, and crouches in the shadows steep
That in the gloomy wave go diving fathoms deep.
And well she may, to spy that fearful thing
All down the dusky walls in circlets wound;
Alas! for what rare prize, with many a ring
Girding the marble casket round and round?
