Judgement

All that is gold does not glitter
All that is gold does not glitter;
all that is long does not last;
All that is old does not wither;
not all that is over is past.

The second quatrain was added during the following revision:

Not all that have fallen are vanquished;
a king may yet be without crown,
A blade that was broken be brandished;
and towers that were strong may fall down.
Christopher TolkienĀ
