"Woe to the vanquished!" Shouted Brennus as he threw his sword on the scales. He had just finished sacking Rome and was weighing out the 1,000 pounds of gold that the defending Romans would pay to ransom the remainder of the city. After a complaint that the scales were rigged, he threw his sword on the weights because, well, he could.
That was 390 BCE. The Romans took that motto to heart. By 51 BCE Julius Caesar was using the same phrase as he conquered and crushed all of Gaul, where the descendants of Brennus lived. Out of an estimated three million Gauls, Romans killed one million of them, and took another million into slavery.
