It is clear, then, according to Pliny, at one time, it was believed that the competition of Gallic dyers might have ruined the Oriental, and would have done so, had the tenacity of their vegetable colouring equalled its beauty. In another passage Pliny tells us that these Gallic stuffs were used especially by the slaves and the populace.

The wool industry made no less progress in Gaul than weaving and dyeing. From numerous passages in Juvenal and Martial it appears that the woollen clothing worn by the populace of Rome in the second century was woven in Gaul, particularly in the districts to-day known as Arras, Langres, Saintonge. Pliny attributes to the Gauls the invention of a wool, that, soaked in acid, became incombustible, and was used to make mattresses.

Glass-making was another art carried from the East across the Mediterranean into Gaul. Still another industry, metallurgy, after weaving, contributed greatly to enrich Gaul. Undoubtedly even before the Roman conquest, Gaul worked gold mines; it seems, however, that silver mines remained untouched until about the time of Augustus. At any rate, the discovery of some deposits of gold and silver then gave a spur to several flourishing industries; jewelry-making, and—an original Gallic industry of much importance—silver-plating and tinning. Here is another extract from Pliny, from which you will see that in those times they already made in France "Christofle" silver-plate:

They cover [writes Pliny] the copper with tin in such a way that it is difficult to distinguish it from silver. It is a Gallic invention. Later they began to do the same thing with silver, silver-plating especially the ornaments of horses and carriages. The merit of the invention belongs to the Biturigi, and the industry was developed in the city of Alesia. After the same fashion there has been spread everywhere a foolish profusion of objects not only silver-, but gold-plated. All that is called cultus, elegance!

We might almost say that Gallic industry did to the old industries of the ancient world what German wares have done compared with older and more aristocratic products of France, of England, popularising objects of luxury for the many and the merely well-to-do.

Finally, if any one hesitated to trust fully these very important passages in Pliny, he would be quite convinced by reading the great work of Dechelette. This author, studying with Carthusian patience and the ablest critical acumen the Gallic ceramics to be found scattered among the museums, has demonstrated most commendably that in the first century of the Empire many manufactories of ceramics were opened and flourished in Gaul, especially in the valley of the Allier, and that they sold their vases in Spain, in the Danube regions, to the Germans, and in Italy.

Dechelette has proved that many ceramics found among the ruins of Pompeii, now admired in the museums of Pompeii and Naples, were made in Gaul,—discoveries most noteworthy, which, in connection with the extracts from Pliny, disclose in essence that real Roman Gaul whose sumptuous relics but half tell the tale of its wealth.

This tremendous development of Gaul was without doubt an effect of the Roman conquest; but an effect that neither Cæsar, nor any other man of his times had foreseen or willed, but which Augustus was first to recognise in the winter of 15-14 B.C., and to which, astute man that he was, he gave heed as he ought; that is, not as due his own merit, but as an unexpected piece of good fortune. I have already said that one of the greatest cares of Augustus, as soon as the civil wars were finished, was to reorganise the finances of the Empire; that to find new entries for the treasury, he had turned his attention in 27 B.C. to the province conquered by his father, regarding it merely from the common point of view, as poor and of little worth like the other European territories. Then, at a stroke, he realised that that territory so lightly valued, was producing grain like Egypt, linen like Egypt; that the arts of civilisation for which Egypt was so rich and famous were beginning to prosper there! Augustus was not the man to let slip so tremendous a piece of good luck. Until then he had hesitated, like one who seeks his way; in that winter from 15-14 B.C., he found finally the grand climax of his career, to make Gaul the Egypt of the West, the province of the greatest revenues in Europe. From that time on to the end of his life, he did not move from Europe; he lived between Italy and Gaul. Like him, Tiberius, Drusus, all the men of his family, devoted all their efforts to Gaul, to consolidating Roman dominion there, to advancing its progress, to increasing the revenues, to making it actually the Occidental Egypt. From Velleius we learn that under Tiberius Gaul rendered to the Empire as much as did Egypt, and that Gaul and Egypt were considered alike the two richest imperial provinces.

As a political interest had at first impelled Cæsar to annex Gaul, an immediate financial interest urged Augustus to continue the work, to take care of the new province. Then the historic law that I have already enunciated to you, the law by which the efforts of men result far differently from that which they had intended, was verified anew by Augustus also, and in a new form. He had created his Gallic policy to augment the revenues of the Empire; the consequences of this fiscal policy, necessity-inspired, were greater than he and his friends ever dreamed. The winter of 15-14 B.C. is a notable date in the story of Latin civilisation, for then the destiny of the Empire was irrevocably settled; the Roman Empire will be made up of two parts, the Oriental and the Occidental, each part sufficiently strong to withstand being overcome by the other; it will be neither an Asiatic, nor a Celtic-Latin, but a mixed Empire: between both parts, Italy will rule for two centuries more, and Rome, an immense city, at once Oriental and Latin, will keep the metropolitan crown won from the enfeebled East, and dominate the immature barbarian West.

Speaking of Cleopatra, I have shown you how great was the Oriental peril that threatened in the last century of the Republic to wipe out Rome. What miraculous force saved it? Gaul. Suppose that the army of Cæsar had been exterminated at Alesia; suppose that Rome, discouraged, had abandoned its Gallic enterprise as it had done with Persia, after the disaster of Crassus and the failure of Antony; or suppose that Gaul had been a poor province, sterile and unpopulous, like many a Danube district; Rome could not have held out long as the seat of imperial government, just as to-day the capital of the Russian Empire could not maintain itself at Vladivostok or Harbin. It would have been necessary to move the metropolis to a richer and more populous region. That Gaul grew rich and was Romanised, changed the state of things. When Rome possessed beyond the Alps in Europe a province as large and as full of resources as Egypt; when there was the same interest in defending it as in defending Egypt, Italy was well placed to govern both. The Egypt of the Occident counterbalanced the Egypt of the Orient, and Rome, half way between, was the natural and necessary metropolis of the wide-spread Empire. Gaul alone, revived, so to speak, the Empire in the West and prevented the European provinces—even Italy itself—from becoming dead limbs safely amputable from the Oriental body. Gaul upheld Italy and Rome in Europe for three centuries longer; Gaul stopped it on the way to the Asiatic conquests run through by Alexander. Had it not been for Gaul, Asia Minor, Syria, and Egypt would have formed the real Empire of Rome, and Italy would have been lost in it: without Gaul, the Orientalised Empire would have tried to conquer Persia and probably succeeded in doing so, abandoning the poor and unproductive lands of the untamed Occident. In short, Gaul created in the Roman Empire that duality between East and West which gives shape to all the history of our civilisation; it kept the artificial form of the Empire, circular about an island sea; it inspired the Empire with that double self-contradictory spirit, Latin and Oriental, at once its strength and its weakness.
