To these advantageous conditions, which, being physical, existed before the Roman conquest, the conquest added some others: it broke down the political barrier that previously cut off these convenient means of penetration, the rivers; it suppressed the wars between the Gallic tribes, the privileges, the tyrannies, the tolls, the monopolies; it saved the enormous resources that were previously wasted in these constant drains; it put again the hoe, the spade, the tools of the artisan, into hands that had before been wielding the sword; and finally, it consolidated (and this was perhaps the most important effect) the jurisdiction of property. When Cæsar invaded Gaul, the great landowners still cultivated cereals and textile plants but little; they put the greater part of their fortune into cattle, exactly because in that regime of continual war and revolution lands easily kept changing proprietors. Furthermore, the more frequent contact with Rome acquainted the Gauls with Roman agriculture and its abler methods, with Latin life and its studied order.
By the combination of all these causes, population and production increased rapidly. The gain in population was so considerable that the ancients themselves noticed it. Strabo (Bk. 4, ch. i, §2) observes that the Gallic women are fecund mothers and excellent nurses. With the population, wealth increased on all sides, in agriculture as in industry and in trade.
The new and more stable jurisdiction of the landed proprietary generated another most important effect; it promoted rapidly the cultivation of cereals and textile plants, of wheat and flax. "All Gaul produces much wheat," says Strabo, and we read his notice without surprise, because we know that France is, even to-day, the region of Europe most fertile in cereals. There is no reason to suppose that it must have been barren of them twenty centuries ago. Other documentary evidence, particularly inscriptions, confirms Strabo, informing us that, especially in the second century, Rome bought the customary grain to feed the metropolis not only in Egypt, but also in Gaul. In short, Gaul seems to have been the sole region of Europe fertile enough to be able to export grain, to have been for Rome a kind of Canada or Middle West of the time, set not beyond oceans but beyond the Alps.
The cultivation of flax, to the ancient world what cotton is to-day, progressed rapidly in Gaul along with that of wheat, so that Gaul was early able to rival Egypt also in this respect. That Gaul and Egypt should have so much in common at the same time, was something so interesting and seemed so strange that Pliny himself wrote:
Flax is sowed only in sandy places and after a single ploughing. Perhaps Egypt may be pardoned for sowing it, because with it she buys the merchandise of India and Arabia. But, look you!—even Gaul is famous for this plant. What matters it, if huge mountains shut away the sea; if on the ocean side it has for confines what is called emptiness? Notwithstanding that, Gaul cultivates flax like Egypt: the Cadurci, the Caleti, the Ruteni, the Biturigi, the Morini, who are considered tribes of the ends of the earth … but what am I saying? All Gaul makes sails,—till the enemies beyond the Rhine imitate them, and the linen is more beautiful to the eyes than are their women.
These descriptions show Gaul to be one of the new countries, like the Argentine Republic or the United States, in which the land has still almost its natural pristine fecundity and brings forth a marvellous abundance of plants that clothe and nourish man. We know that in Gaul under the Empire there were immense fortunes in land in face of which the fortunes of wealthy Italian proprietors shrink like the fortunes of Europe when compared with the great ranch fortunes of the Argentine Republic or the United States. Twenty years ago they began to excavate in France the ruins of the great Gallo-Roman villas: these are constructed on the plan of the Italian villa, decorated in the same way, but are much larger, more sumptuous, more sightly; one feels in them the pride of a new people which has adopted the Latin civilisation, but has infused into that, derived from the wealth of their land, a spirit of grandeur and of luxury that poorer and older Latins did not know, exactly as to-day the Americans infuse a spirit of greater magnitude and boldness into so many things that they take from timid, old Europe. Perhaps there was also in this Gallic luxury, as in the American, a bit of ostentation, intended to humiliate the masters remaining poorer and more modest.
But Gaul was a nation not only rich in fertilest agriculture; side by side with that, progressed its industry. This, according to my notion, is one of the vital points in ancient history. Under the Roman domination, Gaul was not restricted to the better cultivation of its productive soil; but alone among the peoples of the Occident, became, as we might now say, an industrial nation, that manufactured not only by and for itself, but like Asia Minor, Egypt, Syria, sold also to other peoples of the Empire and outside of its own boundaries; in a word, exported. The more frequent contact with the Orient better acquainted the Gauls with the beautiful objects made by the artisans of Laodicea, of Tyre, of Sidon; and the clever genius of the Celt, always apt in industry, drew from them incentive to create a Gallic industry, partly imitative, partly original, and to seek a large clientèle for these industries in Italy, in Spain, beyond the Rhine, among the Germans, in the Danube provinces. This is proved by a number of important passages in Pliny, confirmed by inscriptions and archæological discoveries.
Pliny has already told us that the Gauls manufactured many linen sails; we know also that they made not only rough sails, but also fine linen for clothing, which had a wide market. There have been found in the Orient numerous fragments of an inscription containing the famous edict of Diocletian on maximum sale prices allowed, an inscription of value to us for its nomenclature of ancient fabrics. In this nomenclature is mentioned the birrus of Laodicea, an imitation of the birrus of the Nervii, which was a very fine linen cloth, worn by ladies of fashion. Laodicea was one of the most ancient centres of Oriental textile fabrics; the Nervii were one of the most remote of the Gallic peoples, living—the coincidence is noteworthy—about where Flanders is now. If at Laodicea they made at the end of the third century an imitation of Nervian linen, that means that the Nervii had succeeded in manufacturing and finding market for cloth so desirable as to rouse the Laodiceans, competing for trade, to imitate it. What proof more persuasive that during the early centuries of the Empire the Gauls greatly improved their industries and widened their markets?
They had mastered weaving, but they did not stop there; they invented new methods of dyeing, using vegetable dyes instead of the customary animal colours of the Orient. Pliny says:
The Gaul imitates with herbs all colours, including Tyrian purple; they do not seek the mollusk on the sea bottom; they run no risk of being devoured by sea monsters; they do not exploit the anchorless deep to multiply the attractions of the courtesan, or to increase the powers of the seducer of another's wife. They gather the herbs like cereals, standing on the dry ground; although the colour that they derive does not bear washing. Luxury could thus be gratified with greater show at the cost of fewer dangers.
