All that is gold does not glitter,
Not all those who wander are lost;
The old that is strong does not wither,
Deep roots are not reached by the frost.
From the ashes a fire shall be woken,
A light from the shadows shall spring;
Renewed shall be blade that was broken,
The crownless again shall be king.
It seems that Tolkien is just as casual about the quotation as most people.
In Shakespeare's Merchant of Venice the Prince of Morocco actually says:-"All that glisters is not gold;
Often have you heard that told.
Many a man his life hath
But my outside to behold.
Gilded tombs do worms enfold."It is glisters and
OT glitters in the original version.
