All that glisters is not gold

O hell! what have we here?
A carrion Death, within whose empty eye
There is a written scroll! I'll read the writing.
'All that glisters is not gold,
Often have you heard that told;
Many a man his life hath sold
But my outside to behold:
Gilded tombs do worms infold.
Had you been as wise as bold,
Young in limbs, in judgment old,
Your answer had not been inscroll'd:
Fare you well, your suit is cold.'
Cold indeed; and labour lost:
Then, farewell, heat, and welcome, frost!
Portia, adieu! I have too griev'd a heart
To take a tedious leave; thus losers part.

The Merchant of Venice (II, vii)
