After Caesar, Augustus, left sole master of the Roman world, assumed in Gaul, as elsewhere, the part of pacificator, repairer, conservator, and organizer, whilst taking care, with all his moderation, to remain always the master. He divided the provinces into imperial and senatorial, reserving to himself the entire government of the former, and leaving the latter under the authority of the senate. Gaul “of the long hair,” all that Caesar had conquered, was imperial province. Augustus divided it into three provinces, Lugdunensian (Lyonese), Belgian, and Aquitanian. He recognized therein sixty nations or distinct cityships which continued to have themselves the government of their own affairs, according to their traditions and manners, whilst conforming to the general laws of the empire, and abiding under the supervision of imperial governors, charged with maintaining everywhere, in the words of Pliny the Younger, “the majesty of Roman peace.” Luydunum (Lyons), which had been up to that time of small importance and obscure, became the great town, the favorite cityship and ordinary abiding-place of the emperors when they visited Gaul. After having held at Narbonne (27 B.C.) a meeting of representatives from the different Gallic nations, Augustus went several times to Lyons, and even lived there, as it appears, a pretty long while, to superintend, no doubt, from thence, and to get into working order the new government of Gaul. After the departure of Augustus, his adopted son Drusus, who had just fulfilled, in Belgica and on the Rhine, a mission at the same time military and administrative, called together at Lyons delegates from the sixty Gallic cityships, to take part (B.C.12 or 10) in the inauguration of a magnificent monument raised, at the confluence of the Rhone and Saone, in honor of Rome and Augustus as the tutelary deities of Gaul. In the middle of a vast enclosure was placed a huge altar of white marble, on which were engraved the names of the sixty cityships “of the long hair.” A colossal statue of the Gauls and sixty statues of the Gallic cityships occupied the enclosure. Two columns of granite, twenty-five feet high, stood close by the altar, and were surmounted by two colossal Victories, in white marble, ten feet high. Solemn festivals, gymnastic games, and oratorical and literary exercitations accompanied the inauguration; and during the ceremony it was announced, amidst popular acclamation, that a son had just been born to Drusus at Lyons itself, in the palace of the emperor, where the child’s mother, Antonia, daughter of Marc Antony and Octavia (sister of Augustus), had been staying for some months. This child was one day to be the emperor Claudius.
