From The Aenid

Other peoples will cast their breathing figures more tenderly in bronze,
Truly, I believe, and draw out of marble more lifelike expressions,
Plead causes better, trace the paths of heaven with wands,
And tell the rising constellations.
But you will rule nations by your strength,
Remember, Roman, these will be your arts:
To pacify, to impose the rule of law,
To spare the defeated, to conquer the proud.

By Virgil, Aeneid

Excudent alii spirantia mollius aera
(credo equidem), vivos ducent de marmore vultus,
orabunt causus melius, caelique meatus
describent radio et surgentia sidera dicent.
Tu regere imperio populos, Romane, memento
(hae tibi erunt artes): Pacique imponere morem,
parcere subiectis et debellare superbos.
