And you, my Tyrians,
harry with hatred all his line, his race to come:
make that offering to my ashes, send it down below.
No love between our peoples, ever, no pacts of peace!
Come rising up from my bones, you avenger still unknown,
to stalk those Trojan settlers, hunt with fire and iron,
now or in time to come, whenever the power is yours.
Shore clash with shore, sea against sea, and sword
against sword — this is my curse — war between all
our peoples, all their children, endless war!

[Tum vos, o Tyrii, stirpem et genus omne futurum
exercete odiis, cinerique haec mittite nostro
munera. Nullus amor populis, nec foedera sunto.
Exoriare aliquis nostris ex ossibus ultor,
qui face Dardanios ferroque sequare colonos,
nunc, olim, quocumque dabunt se tempore vires.
Litora litoribus contraria, fluctibus undas
imprecor, arma armis; pugnent ipsique nepotesque.]

O Tyrians, strive this Nation to supplant
With restless wars this to my ashes grant:
Never joyn leagues, contract no amities,
And from our bones let some revenger rise,
Who Trojans may pursue with fire, and sword,
Ah, may when ever time shall strength afford,
Shores shores oppose, seas seas, our stocks debate
With arms gainst arms maintaine, I imprecate.
[tr. Ogilby (1649)]

And you, my Tyrians, ev'ry curse fulfil.
Perpetual hate and mortal wars proclaim,
Against the prince, the people, and the name.
These grateful off'rings on my grave bestow;
Nor league, nor love, the hostile nations know!
Now, and from hence, in ev'ry future age,
When rage excites your arms, and strength supplies the rage
Rise some avenger of our Libyan blood,
With fire and sword pursue the perjur'd brood;
Our arms, our seas, our shores, oppos'd to theirs;
And the same hate descend on all our heirs!
[tr. Dryden (1697)]

And, Tyrians, you through time to come
His seed with deathless hatred chase:
Be that your gift to Dido's tomb:
No love, no league 'twixt race and race.
Rise from my ashes, scourge of crime,
Born to pursue the Dardan horde
To-day, to-morrow, through all time,
Oft as our hands can wield the sword:
Fight shore with shore, fight sea with sea,
Fight all that are or e'er shall be!
[tr. Conington (1866)]

And ye, O Tyrians, follow with your hate
His seed, and all his future race! Be this
Your offering on my tomb! No love, no league
Between you ! Oh, may some avenger rise
From out my ashes, who with fire and sword
Shall chase these Dardan settlers, now, and in
The coming time, wherever strength is given;
Shores with shores fighting, waves with waves, and
arms With arms, -- they and their last posterity
[tr. Cranch (1872)]

And you, O Tyrians, hunt his seed with your hatred for all ages to come; send this guerdon to our ashes. Let no kindness nor truce be between the nations. Arise out of our dust, O unnamed avenger, to pursue the Dardanian settlement with firebrand and steel. Now, then, whensoever strength shall be given, I invoke the enmity of shore to shore, wave to water, sword to sword; let their battles go down to their children's children.
[tr. Mackail (1885)]

And ye, O Tyrians, 'gainst his race that is, and is to be,
Feed full your hate! When I am dead send down this gift to me:
No love betwixt the peoples twain, no troth for anything!
And thou, Avenger of my wrongs, from my dead bones outspring,
To bear the fire and the sword o'er Dardan-peopled earth
Now or hereafter; whensoe'er the day brings might to birth.
I pray the shore against the shore, the sea against the sea,
The sword 'gainst sword -- fight ye that are, and ye that are to be!
[tr. Morris (1900)]

Them and their children's children evermore
Ye Tyrians, with immortal hate outwear.
This gift -- 'twill please me best -- for Dido's shade prepare.
This heritage be yours; no truce nor trust
'Twixt theirs and ours, no union or accord
Arise, unknown Avenger from our dust;
With fire and steel upon the Dardan horde
Mete out the measure of their crimes' reward.
To-day, to-morrow, for eternity
Fight, oft as ye are able -- sword with sword,
Shore with opposing shore, and sea with sea;
Fight, Tyrians, all that are, and all that e'er shall be!
[tr. Taylor (1907)], st. 81-82, l. 720ff]

And -- O ye Tyrians! I
sting with your hatred all his seed and tribe
forevermore. This is the offering
my ashes ask. Betwixt our nations twain,
No love! No truce or amity! Arise,
Out of my dust, unknown Avenger, rise!
To harry and lay waste with sword and flame
those Dardan settlers, and to vex them sore,
to-day, to-morrow, and as long as power
is thine to use! My dying curse arrays
shore against shore and the opposing seas
in shock of arms with arms. May living foes
pass down from sire to son insatiate war
[tr. Williams (1910)]

Then do ye, O Tyrians, pursue with hate his whole stock and the race to come, and to my dust offer this tribute! Let no love nor league be between the nations. Arise from my ashes, unknown avenger! to chase with fire and sword the Dardan settlers, to-day, hereafter, whenever strength be given! May shore with shore clash, I pray, waters with waters, arms with arms; may they have war, they and their children's children!
[tr. Fairclough (1916)]

And you, O Tyrians, hate, and hate forever
The Trojan stock. Offer my dust this homage.
No love, no peace, between these nations, ever!
Rise from my bones, O great unknown avenger,
Hunt them with fire and sword, the Dardan settlers,
Now, then, here, there, wherever strength is given.
Shore against shore, wave against wave, and war,
War after war, for all the generations.
[tr. Humphries (1951)]

Let you, my Tyrians, sharpen your hatred upon his children
And all their seed for ever: send this as a present to
My ghost. Between my people and his, no love, no alliance!
Rise up from my dead bones, avenger! Rise up, one
To hound the Trojan settlers with fire and steel remorselessly,
Now, some day, whenever the strength for it shall be granted!
Shore to shore, sea to sea, weapon to weapon opposed --
I call down a feud between them and us to the last generation!
[tr. Day-Lewis (1952)]

Then, Tyrians, hunt down
with hatred all his sons and race to come;
send this as offering unto my ashes.
Do not let love or treaty tie our peoples.
May an avenger rise up from my bones,
one who will track with firebrand and sword
the Dardan settlers, now and in the future,
at any time that ways present themselves.
I call your shores to war against their shores,
your waves against their waves, arms with their arms.
Let them and their sons' sons learn what is war.
[tr. Mandelbaum (1971)]

Then, O my Tyrians, besiege with hate
His progeny and all his race to come:
Make this your offering to my dust. No love,
No pact must be between our peoples; No,
But rise up from my bones, avenging spirit!
Harry with fire and sword the Dardan countrymen
Now, or hereafter, at whatever time
The strength will be afforded. Coast with coast
In conflict, I implore, and sea with sea,
And arms with arms: may they contend in war,
Themselves and all the children of their children!
[tr. Fitzgerald (1981), l. 865ff]

As for you, my Tyrians, you must pursue with hatred the whole line of his descendants in time to come. Make that your offering to my shade. Let there be no love between our peoples and no treaties. Arise from my dead bones, O my unknown avenger, and harry the race of Dardanus with fire and sword wherever they may settle, now and in the future, whenever our strength allows it. I pray that we may stand opposed, shore against shore, sea against sea, and sword against sword. Let there be war between the nations and between their sons forever.
[tr. West (1990)]

Then, O Tyrians, pursue my hatred against his whole line
and the race to come, and offer it as a tribute to my ashes.
Let there be no love or treaties between our peoples.
Rise, some unknown avenger, from my dust, who will pursue
the Trojan colonists with fire and sword, now, or in time
to come, whenever the strength is granted him.
I pray that shore be opposed to shore, water to wave,
weapon to weapon: let them fight, them and their descendants.
[tr. Kline (2002)]

And you, my Tyrians, must persecute his line
Throughout the generations -- this your tribute
To Dido's ashes. May treaties never unite
These nations, may no love ever be lost between them
And from my bones may some avenger rise up
To harry the Trojans with fire and sword,
Now and whenever we have the power.
May coast oppose coast, waves batter waves,
Arms clash with arms, may they be ever at war,
They themselves and their children forever.
[tr. Lombardo (2005)]

Tyrians, you must torment his sons
and all his future race. Make this offering to my ashes.
Let there be no love or treaties between us.
Rise from my bones, unknown avenger,
hunt the Dardan colonists with flames and swords,
now or any times there's strength to strike!
My curse is this: our lands, our seas, our swords will clash.
The Trojans will fight wars for generations.
[tr. Bartsch (2021)]
