Est etiam frater, cuius manus impia poscit
 Respergi nostro, sparsacruore uiri.
 Pone deos et quae tangendo sacra profanas:
 Non bene caelestes impia dextra colit.
 Si tu cultor eras elapsis igne futurus
 Paenitet elapsos ignibus esse deos.
 Forsitan et grauidam Dido, scelerate, relinquas
 Parsque tui lateat corpore clausa meo.
 Accedet fatis matris miserabilis infans,
 Et nondum nato funeris auctor eris,
 Cumque parente sua frater morietur Iuli,
 Poenaque conexos auferetuna duos.
 ‘sed iubet ire deus.’ Uellem uetuisset adire,
 Punica nec Teucris pressafuisset humus!

 Indeed, there is a brother, to whose wretched hand of the man is able to be splashed on
me, having been dampened, with my blood.  Put down those
images of the Gods1 and you desecrate1 the unholy relics which must be
moved:  the wretched right hand does not adorn the Gods well.  If you,
having escaped the love, were being a future cultivator, then it is
regrettable that the Gods escaped these fires.  And perhaps you,
wickedly, leave pregnant Dido and may a part from my body be unknown to
your enclosures.  Will the infant of the miserable mother be added to
the doom1, and not yet will you be the originator of death for the born
one, and when the brother of Ascanius dies by her preparing, and one
punishment takes away the two joined together.  “But the God commands
you to go.”  I wish that he had forbidden1 you to go, the land Carthage having
been pressed by the Teucreans had not been.
