Dulce et decorum est pro patria mori
Dulce et decorum est pro patria mori is a line from the Roman lyrical poet Horace's Odes (III.2.13). The line can be roughly translated into English as: "It is sweet and right to die for your country."
The poem from which the line comes exhorts Roman citizens to develop martial prowess such that the enemies of Rome, in particular the Parthians, will be too terrified to resist them. In John Conington's translation, the relevant passage reads:
To suffer hardness with good cheer,
In sternest school of warfare bred,
Our youth should learn; let steed and spear
Make him one day the Parthian's dread;
Cold skies, keen perils, brace his life.
Methinks I see from rampired town
Some battling tyrant's matron wife,
Some maiden, look in terror down,—
“Ah, my dear lord, untrain'd in war!
O tempt not the infuriate mood
Of that fell lion I see! from far
He plunges through a tide of blood!”
What joy, for fatherland to die!
Death's darts e'en flying feet o'ertake,
Nor spare a recreant chivalry,
A back that cowers, or loins that quake.
A humorous elaboration of the original line was used as a toast in the 19th century: "Dulce et decorum est pro patria mori, sed dulcius pro patria vivere, et dulcissimum pro patria bibere. Ergo, bibamus pro salute patriae." In English this is rendered as: "It is sweet and dignified to die for the homeland, but it is sweeter to live for the homeland, and the sweetest to drink for it. Therefore, let us drink to the health of the homeland."
Uses in art and literature 
- Perhaps the most famous modern use of the phrase is as the title of a poem, "Dulce Et Decorum Est", by British poet Wilfred Owen during World War I. Owen's poem describes a gas attack during World War I and is one of his many anti-war poems that were not published until after the war ended. In the final lines of the poem, the Horatian phrase is described as "the old lie." It is believed[by whom?] that Owen intended to dedicate the poem ironically to Jessie Pope, a popular writer who glorified the war and recruited "laddies" who "longed to charge and shoot" in simplistically patriotic poems like "The Call."
- "Died some, pro patria, non 'dulce' non 'et decor'..." from part IV of Ezra Pound's "Hugh Selwyn Mauberley", a damning indictment of World War I; "Daring as never before, wastage as never before."
- In a school essay German playwright Bertolt Brecht referred to the phrase as "Zweckpropaganda" (cheap propaganda for a specific cause) and pointed out, that "It is sweeter and more fitting to live for one's country."
- The title of Damon Knight's 1955 short story "Dulcie and Decorum" is an ironic play on the first three words of the phrase; the story is about computers that induce humans to kill themselves.
