It has been suggested that it was written for Thomas' dying father, although he did not die until just before Christmas 1952. It has no title other than its first line, Do not go gentle into that good night, a line which appears as a refrain throughout. Its other refrain is Rage, rage against the dying of the light. The poem currently remains under copyright, but was made publicly available here [1] at poets.org (with the copyright holder's permission).
This term is a shortening of William Congreve's lines, Heav'n has no rage, like love to hatred turn'd, nor Hell a fury like a woman scorn'd ( The Mourning Bride, 1697). Similar lines appear in several plays of the same period. Today the proverb is often shortened even more, as in the example.
