The Insatiable Eye

--'Lo! then this skull -- which if thou wilt regard, 
And to my question seek for fit reply, 
All thy long labours shall have full reward. 

'Once in that hollow circle lodged an eye, 
That was, like thine, for ever coveting, 
Which worlds on worlds had failed to satisfy. 

'Now while thou gazest on that ghastly ring, 
From whence of old a greedy eye outspied, 
Say thou what was it, -- for there was a thing,-- 

'Which filled at last and throughly satisfied 
The eye that in that hollow circle dwelt, 
So that, 'Enough, I have enough,' it cried.' 

Richard Chenebix Trench, from "Alexander at the Gates of Paradise"
