"Life's but a walking shadow..."
Metaphor
Act 5,
Scene 5
Lines 19-28
Macbeth
In this pivotal speech, Macbeth uses theater imagery to metaphorically compare life to a play on stage. To put his words another way, life is like a story told by some insignificant actor, who rants and rages on the stage for an hour, then never to be heard from again—a story, seemingly full of passion and action, that ultimately is meaningless.
