While the Celtic and Ligurian population of these regions was thus in the course of losing its nationality, and was languishing and pining withal under a political and economic oppression, the intolerable nature of which is sufficiently attested by their hopeless insurrections, the decline of the native population here went hand in hand with the naturalizing of the same higher culture which we find at this period in Italy. Aquae Sextiae and still more Narbo were considerable townships, which might probably be named by the side of Beneventum and Capua; and Massilia, the best organized, most free, most capable of self-defence, and most powerful of all the Greek cities dependent on Rome, under its rigorous aristocratic government to which the Roman conservatives probably pointed as the model of a good urban constitution, in possession of an important territory which had been considerably enlarged by the Romans and of an extensive trade, stood by the side of those Latin towns as Rhegium and Neapolis stood in Italy by the side of Beneventum and Capua.
Matters wore a different aspect, when one crossed the Roman frontier. The great Celtic nation, which in the southern districts already began to be crushed by the Italian immigration, still moved to the north of the Cevennes in its time-hallowed freedom. It is not the first time that we meet it: the Italians had already fought with the offsets and advanced posts of this vast stock on the Tiber and on the Po, in the mountains of Castile and Carinthia, and even in the heart of Asia Minor; but it was here that the main stock was first assailed at its very core by their attacks. The Celtic race had on its settlement in central Europe diffused itself chiefly over the rich river-valleys and the pleasant hill-country of the present France, including the western districts of Germany and Switzerland, and from thence had occupied at least the southern part of England, perhaps even at this time all Great Britain and Ireland[10]; it formed here more than anywhere else a broad, geographically compact, mass of peoples. In spite of the differences in language and manners which naturally were to be found within this wide territory, a close mutual intercourse, an innate sense of fellowship, seems to have knit together the tribes from the Rhone and Garonne to the Rhine and the Thames; whereas, although these doubtless were in a certain measure locally connected with the Celts in Spain and in the modern Austria, the mighty mountain barriers of the Pyrenees and the Alps on the one hand, and the encroachments of the Romans and the Germans which also operated here on the other, interrupted the intercourse and the intrinsic connection of the cognate peoples far otherwise than the narrow arm of the sea interrupted the relations of the continental and the British Celts. Unhappily we are not permitted to trace stage by stage the history of the internal development of this remarkable people in these its chief seats; we must be content with presenting at least some outline of its historical culture and political condition, as it here meets us in the time of Caesar.
Gaul was, according to the reports of the ancients, comparatively well peopled. Certain statements lead us to infer that in the Belgic districts there were some 200 persons to the square mile - a proportion such as nearly holds at present for Wales and for Livonia - in the Helvetic canton about 245[11]; it is probable that in the districts which were more cultivated than the Belgic and less mountainous than the Helvetian, as among the Bituriges, Arverni, Haedui, the number rose still higher. Agriculture was no doubt practised in Gaul - for even the contemporaries of Caesar were surprised in the region of the Rhine by the custom of manuring with marl[12], and the primitive Celtic custom of preparing beer (cervesia) from barley is likewise an evidence of the early and wide diffusion of the culture of grain - but it was not held in estimation. Even in the more civilized south it was reckoned not becoming for the free Celts to handle the plough. In far higher estimation among the Celts stood pastoral husbandry, for which the Roman landholders of this epoch very gladly availed themselves both of the Celtic breed of cattle, and of the brave Celtic slaves skilled in riding and familiar with the rearing of animals[13]. Particularly in the northern Celtic districts pastoral husbandry was thoroughly predominant. Brittany was in Caesar's time a country poor in corn. In the north-east dense forests, attaching themselves to the heart of the Ardennes, stretched almost without interruption from the German Ocean to the Rhine; and on the plains of Flanders and Lorraine, now so fertile, the Menapian and Treverian herdsman then fed his half-wild swine in the impenetrable oak-forest.
Just as in the valley of the Po the Romans made the production of wool and the culture of corn supersede the Celtic feeding of pigs on acorns, so the rearing of sheep and the agriculture in the plains of the Scheldt and the Maas are traceable to their influence. In Britain even the threshing of corn was not yet usual; and in its more northern districts agriculture was not practised, and the rearing of cattle was the only known mode of turning the soil to account. The culture of the olive and vine, which yielded rich produce to the Massiliots, was not yet prosecuted beyond the Cevennes in the time of Caesar.
The Gauls were from the first disposed to settle in groups; there were open villages everywhere, and the Helvetic canton alone numbered in 696 four hundred of these, besides a multitude of single homesteads. But there were not wanting also walled towns, whose walls of alternate layers surprised the Romans both by their suitableness and by the elegant interweaving of timber and stones in their construction; while, it is true, even in the towns of the Allobroges the buildings were erected solely of wood. Of such towns the Helvetii had twelve and the Suessiones an equal number; whereas at all events in the more northern districts, such as among the Nervii, while there were doubtless also towns, the population during war sought protection in the morasses and forests rather than behind their walls, and beyond the Thames the primitive defence of the wooden barricade altogether took the place of towns and was in war the only place of refuge for men and herds.
10. An immigration of Belgic Celts to Britain continuing for a considerable time seems indicated by the names of English tribes on both banks of the Thames borrowed from Belgic cantons; such as the Atrebates, the Belgae, and even the Britanni themselves, which word appears to have been transferred from the Brittones settled on the Somme below Amiens first to an English canton and then to the whole island. The English gold coinage was also derived from the Belgic and originally identical with it.
11. The first levy of the Belgic cantons exclusive of the Remi, that is, of the country between the Seine and the Scheldt and eastward as far as the vicinity of Rheims and Andernach, from 9000 to 10,000 square miles, is reckoned at about 300,000 men; in accordance with which, if we regard the proportion of the first levy to the whole men capable of bearing arms specified for the Bellovaci as holding good generally, the number of the Belgae capable of bearing arms would amount to 500,000 and the whole population accordingly to at least 2,000,000. The Helvetii with the adjoining peoples numbered before their migration 336,000; if we assume that they were at that time already dislodged from the right bank of the Rhine, their territory may be estimated at nearly 1350 square miles. Whether the serfs are included in this, we can the less determine, as we do not know the form which slavery assumed amongst the Celts; what Caesar relates (i. 4) as to the slaves, clients, and debtors of Orgetorix tells rather in favour of, than against, their being included.
That, moreover, every such attempt to make up by combinations for the statistical basis, in which ancient history is especially deficient, must be received with due caution, will be at once apprehended by the intelligent reader, while he will not absolutely reject it on that account.
12. "In the interior of Transalpine Gaul on the Rhine", says Scrofa in Varro, De R. R. i. 7, 8, "when I commanded there, I traversed some districts, where neither the vine nor the olive nor the fruit-tree appears, where they manure the fields with white Pit-chalk, where they have neither rock - nor sea-salt, but make use of the saline ashes of certain burnt wood instead of salt". This description refers probably to the period before Caesar and to the eastern districts of the old province, such as the country of the Allobroges; subsequently Pliny (H. N. xvii. 6, 42 seq.) describes at length the Gallo-Britannic manuring with marl.
13. "The Gallic oxen especially are of good repute in Italy, for field labour forsooth; whereas the Ligurian are good for nothing". (Varro, De R. R. ii. 5, 9). Here, no doubt, Cisalpine Gaul is referred to, but the cattle-husbandry there doubtless goes back to the Celtic epoch. Plautus already mentions the "Gallic ponie", (
