Invictus

From Wikipedia: "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).
It originally bore no title: early printings contained only the dedication To R. T. H. B.—a reference to Robert Thomas Hamilton Bruce (1846–1899), a successful Scottish flour merchant and baker who was also a literary patron.
The familiar title "Invictus" (Latin for "unconquered") was added by Arthur Quiller-Couch when he included the poem in The Oxford Book Of English Verse (1900).

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.
