Empires remain alive in our minds by dint of the great works they achieve. And the Roman empire is still the world's preceptor in politics, law, administration and the art of war. Her legal advisors laid the foundations of justice and morals in society; her municipal system has handed down criteria of administration still in use today. The Romans built triumphal arches, the domed Pantheon, aqueducts, circuses and amphitheatres for their captains, the needs of their empire and the pleasure of their great cities, in addition to their military roads which spread their will to the ends of the earth. They also created the Coliseum and the Thermal Baths of Caracella, so majestic they can be taken as a symbol of Roman dominion. The scandal of Roman orgies surpassed anything that had been seen in the Orient; Latin is the parent of many modern languages; and for Cicero, Seneca and Tacitus, the most imperious need was the free possession of the self.
