Just as the conquests of Alexander, by uniting the Orient to Greece, produced a Graeco-Oriental civilization, so now the expansion of Rome over the Mediterranean formed another world-wide culture, in which both Greek and Roman elements met and mingled. A new sense of cosmopolitanism arose in place of the old civic or national patriotism. Roman elements met and mingled. A new sense of cosmopolitanism arose in place of the old civic or national patriotism. [Illustration: A ROMAN TEMPLE The best preserved of Roman temples. Located at Nîmes in southern France, where it is known as La Maison Carrée ("the square house"). The structure is now used as a museum of antiquities.] UNIFYING AND CIVILIZING FORCES This cosmopolitan feeling was the outcome of those unifying and civilizing forces which the imperial system set at work. The extension of Roman citizenship broke down the old distinction between the citizens and the subjects of Rome. The development of Roman law carried its principles of justice and equity to the remotest regions. The spread of the Latin language provided the western half of the empire with a speech as universal there as Greek was in the East. Trade and travel united the provinces with one another and with Rome. The worship of the Caesars dimmed the luster of all local worships and kept constantly before men's minds the idea of Rome and of her mighty emperors. Last, but not least important, was the fusion of alien peoples through intermarriage with Roman soldiers and colonists. "How many settlements," exclaims the philosopher Seneca, "have been planted in every province! Wherever the Roman conquers, there he dwells."

The illustration shows it before the removal of the buildings about 1830 A.D. Bullfights still continue in the arena, where, in Roman times, animal baitings and gladiatorial games took place.] MONUMENTS OF ROMAN RULE The best evidence of Rome's imperial rule is found in the monuments she raised in every quarter of the ancient world. Some of the grandest ruins of antiquity are not in the capital city itself, or even in Italy, but in Spain, France, England, Greece, Switzerland, Asia Minor, Syria, and North Africa. Among these are Hadrian's Wall in Britain, the splendid aqueduct known as the Pont du Gard near Nîmes in southern France, the beautiful temple called La Maison Carrée in the same city, the Olympieum at Athens, and the temple of the Sun at Baalbec in Syria Thus the lonely hilltops, the desolate desert sands, the mountain fastnesses of three continents bear witness even now to the widespreading sway of Rome.
