"Invictus" is a short poem by the English poet William Ernest Henley (1849–1903). It was written in 1875 and first published in 1888 in Henley's Book of Verses, where it was the fourth in a series of poems entitled Life and Death (Echoes).
Out of the night that covers me, Black as the pit from pole to pole, I thank whatever gods may be For my unconquerable soul.
In the fell clutch of circumstance I have not winced nor cried aloud. Under the bludgeonings of chance My head is bloody, but unbowed.
Beyond this place of wrath and tears Looms but the Horror of the shade, And yet the menace of the years Finds and shall find me unafraid.
It matters not how strait the gate, How charged with punishments the scroll, I am the master of my fate: I am the captain of my soul.
