Is "All that glitters is not gold" the correct quotation from The Merchant of Venice?
The original line is as follows:
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 enfold. (II.7)
It is spoken by Morrocco, who is reading from a scroll that was inside a casket (jeweled box). Portia has two caskets: one contains a miniature portrait of her; the other has the scroll. She is using them in a contest to choose who she will marry. "Glister" is an archaic form of the word "glisten." Most often today it is replaced with the word "glitter," as in your question.
