All that glisters is not gold
Prince of Morocco:
"All that glisters is not gold."
Portia is a beautiful, virtuous, wealthy woman who is being
wooed by numerous suitors. She is not free to decide on her own
whom she will marry because her late father stipulated in his will
that she must marry the man who correctly picks the one casket (out
of three) that contains her picture. One casket is gold, another is
silver, and the third is made of lead. The Prince of Morocco is one
in a long line of suitors who tries to win Portia's hand, and he
decides that it would demean Portia to have her picture in anything
other than a gold casket, and so he chooses that one. As he unlocks
it, he is dismayed to find a picture, not of Portia but of Death,
with a message written in its hollow eye: "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."
With a grieving heart the Prince takes hasty leave of Portia, who
is happy to see him go, saying, "A gentle riddance."
