— Tacitus, buch Agricola
Close of chapter 30 http://la.wikisource.org/wiki/De_vita_et_moribus_Iulii_Agricolae_%28Agricola%29#XXX, Oxford Revised Translation
They plunder, they slaughter, and they steal: this they falsely name Empire, and where they make a wasteland, they call it peace.
Loeb Classical Library edition
To plunder, butcher, steal, these things they misname empire: they make a desolation and they call it peace.
As translated by William Peterson
More colloquially: They rob, kill and plunder all under the deceiving name of Roman Rule. They make a desert and call it peace.
This is a speech by the Caledonian chieftain Calgacus addressing assembled warriors about Rome's insatiable appetite for conquest and plunder. The chieftain's sentiment can be contrasted to "peace given to the world" which was frequently inscribed on Roman medals. The last part solitudinem faciunt, pacem appellant (they make a desert, and call it peace) is often quoted alone. Lord Byron for instance uses the phrase (in English) as follows,
Original: (la) Auferre, trucidare, rapere, falsis nominibus imperium; atque, ubi solitudinem faciunt, pacem appellant.
