It is an ancient Mariner, And he stoppeth one of three. 'By thy long grey beard and glittering eye, Now wherefore stopp'st thou me?' 225

-Coleridge, Samuel Taylor

He holds him with his glittering eyeö The Wedding-Guest stood still, And listens like a three years'child: The Mariner hath his will. The Wedding-Guest sat on a stone: He cannot choose but hear; And thus spake on that ancient man, The bright-eyed Mariner.
