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 translated as: "It is sweet and proper to die for one's country."

As a consequence of Wilfred Owen incorporating the phrase into his similarly titled poem, "Dulce et Decorum Est", it is now often referred to as "the Old Lie"; see below.

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:

Angustam amice pauperiem pati
robustus acri militia puer
condiscat et Parthos ferocis
vexet eques metuendus hasta
vitamque sub divo et trepidis agat
in rebus. Illum ex moenibus hosticis
matrona bellantis tyranni
prospiciens et adulta virgo
suspiret, eheu, ne rudis agminum
sponsus lacessat regius asperum
tactu leonem, quem cruenta
per medias rapit ira caedes.
Dulce et decorum est pro patria mori:
mors et fugacem persequitur virum
nec parcit inbellis iuventae
poplitibus timidove tergo.

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." A reasonable English translation would be: "It is sweet and fitting to die for the homeland, but sweeter still to live for the homeland, and sweetest yet to drink for the homeland. So, let us drink to the health of the homeland."
