According to the above interpretation, “the dying of the light” is another metaphor for death in this poem.
“Do Not Go Gentle into That Good Night” is a villanelle in which the poet addresses his father how he ought to die. Dylan Thomas advised his father about how he needs to defy death. The poet also gives an overview of the characterization of the people who defy death and had anger towards it. He uses metaphors and imagery to explain life and death.
