Their form of religion was most probably that common to all the Celts, Druidical worship. Invested with power, civil and spiritual, the Druids held absolute sway over the superstitious Celtic tribes. Proud as the Celts were of their independence, they yet were incapable of governing themselves because of the perpetual dissensions amongst the tribes; and they were overawed by the intellectual superiority of a priesthood that professed all the sciences of the age—medicine, astrology, soothsaying, necromancy—and had taken into its hands the education of the young. The common people were mere blind devotees, and rendered unquestioning obedience to the decrees of the Druids. Druidism was, in fact, the only power which could move the whole Celtic race, and could knit together the Celts of the Thames and those of the Garonne and Rhone, when they met at the great yearly convocation at Chartres, then the "Metropolis of the Earth." Human sacrifice was one of the most cruel and revolting features of the Druidical religion.
The Celts were a peculiarly gifted people, though differing greatly from the contemporary Greeks and Romans. They had been a governing race before the Romans appeared on the stage, and wrested from them the leading part. They had overrun the whole world, so to speak, casting about for a fixed home, and spread as far as the British Isles, making Gaul their religious and political centre, and settled down into more peaceful habits. Driven by excess of population, or their unquenchable thirst for war, or simply their nomadic habits—one cannot otherwise account for their retrogression—they migrated eastwards whence they came—to Italy, Greece, and Asia Minor—demanding territory, and striking terror into every nation they approached by their warlike habits. They knocked at the gates of Rome, and the Galatians were conspicuous by their atrocities.[9] Brilliant qualities and great national faults had been their peculiar characteristics. Quick-witted they were, highly intelligent, ingenious, frank, versatile; attaching much value to gloire, and esprit; susceptible of and accessible to every impression, skilled handicraftsmen; but inclined to be vain, boastful, and fickle-minded, averse to order and discipline, and lacking in perseverance and moral energy. This, according to both ancient and modern writers, was their character. They failed to create a united empire, and to resist their deadly enemy, Rome.
What they did excel in was fighting. Dressed in gaudy costume—wide tunic, bright plaid, and toga embroidered with silver and gold—the Celtic noble would fight by preference in single combat, to show off to personal advantage, but in the brunt of battle he threw away his clothing to fight unimpeded. Bituitus, king of the Arverni, attired in magnificent style, mounts his silver chariot, and, preceded by a harper and a pack of hounds, goes to meet Cæsar in battle, and win his respect and admiration.
The Helvetians were peaceful neighbours to Italy so long as they did not come into direct contact with the Romans, but on the Rhine they were engaged in daily feuds with the German tribes, who had driven them from their settlements in the Black Forest, and had continued their raids beyond the river. For the sake of plunder, or from mere restless habits, the Germans had left their northern homes on the Baltic and North Seas, the Cimbri, and their brethren, the Teutons and others, and were slowly moving southward, repelling or being in turn repelled. The most daring crossed the Rhine, and made their way straight through the lands of the Belgians and Helvetians towards the South, thereby anticipating the great dislocation of peoples which was to take place but five hundred years later, when the Roman Empire, sapped at the root, crumbled to pieces, unable longer to resist the tide of barbarian invasion.
On one of these expeditions the Cimbri, giving a glowing account of sunny Gaul, and the booty to be obtained there, were joined by the Helvetian Tigurini, whose leader was the young and fiery Divico (b.c. 107). They started with the intention of founding a new home in the province of the Nitiobroges in Southern Gaul; but when they had reached that territory they were suddenly stopped on the banks of the Garonne by a Roman army under the consul Cassius and his lieutenant Piso. But, little impressed by the military fame of the Romans, the Tigurini, lying in ambush, gave battle to the forces of great Rome, and utterly routed them at Agen, on the Garonne, between Bordeaux and Toulouse. It was a brilliant victory; both the Roman leaders and the greater part of their men were slain, and the rest begged for their lives. The proud Romans were under the humiliating necessity of giving hostages and passing under the yoke—a stain on the Roman honour not to be forgotten; but the victors, being anything but diplomats, knew no better use to make of their splendid victory than to wander about for a time and then go home again.
A few years later (102 and 101 b.c.) the Tigurini, Toygeni, Cimbri, and Teutons joined their forces on a last expedition southwards. The expedition ended in the destruction of these German tribes. The Toygeni perished in the fearful carnage at Aquæ Sextiæ, and the Cimbri later on at Vercellæ. When the Tigurini heard of this last-mentioned disaster they returned home.
Cæsar had been appointed governor of the Province (Provence) which extended to Geneva, the very door of Helvetia; on the Rhine the Germans continued to make their terrible inroads. Thus there was but little scope for the stirring Helvetians, and the soil afforded but a scanty supply of food; so they turned their eyes wistfully in the direction of fair Gaul. Meeting in council they decided on a general migration, leaving their country to whoever might like to take it. Then rose up Orgetorix, one of their wealthiest nobles, and supported the plan, volunteering to secure a free passage through the neighbouring provinces of the Allobroges and Ædui. The 28th of March, b.c. 58, was the day fixed for the departure, and Geneva was to be the meeting-place; thence they were to proceed through the territory of the Allobroges. For two years previously they were to get ready their provisions, and to collect carts, horses, and oxen, but before the period had expired Orgetorix was accused of treason, and being unable to clear himself, put an end to his own life to escape public obloquy. This episode made no difference in the general plan. The Helvetians, indeed, insisted on its being carried out. Setting fire to their towns and villages to prevent men from returning, they started on their adventurous journey on that spring morn of 58 b.c. Cæsar's figures seem very large, but, if he is to be trusted, the tribes numbered some 368,000 men, of which 263,000 were Helvetians, the rest being neighbours of theirs. But 93,000 were capable of bearing arms.
A curious yet thrilling sight must have been that motley caravan of prodigious proportions—ten thousand carts drawn by forty thousand oxen, carrying women, children, and the old men; riders and armour-bearers alongside, toiling painfully through woods and fords, and up and down rugged hills; behind the emigrants the smoking and smouldering ruins of the homes they were leaving with but little regret. Yet they were no mere adventurers, but looked forward with swelling hearts to a brighter time and a more prosperous home. Arriving at Geneva they found the bridge over the Rhone broken up by Cæsar's order. Cæsar was, in truth, a factor they had not reckoned upon, and, after useless attempts to make headway, they turned their steps towards Mount Jura, and whilst they were toiling over the steep and rugged Pas de l'Ecluse, Cæsar returned to Italy to gather together his legions. Returning to Gaul he arrived just in time to see the Helvetians cross the Arar (Saône) with the utmost difficulty. The Tigurini were the last to cross. And on them Cæsar fell and cut them down, thus avenging the death of Piso—the great-grandfather of Cæsar's wife—and wiping out the stain on the honour of the Roman arms. His legions crossed the Saône in twenty-four hours, and this performance so excited the admiration of the Helvetians, who had themselves taken twenty days to cross, that they condescended to send legates to treat with Cæsar for a free passage. They promised him that they would do no harm to any one if he would comply with the request, but threatened that if he should intercept them he might have to see something of their ancient bravery. No threats or entreaties were of avail, however, with such a man as Cæsar, who, smiling at their naïve simplicity, asked them to gives hostages as a sign of confirmation of their promise. "Hostages!" cried Divico, the hero of of Agen, in a rage, "the Helvetians are not accustomed to give hostages; they have been taught by their fathers to receive hostages, and this the Romans must well remember." So saying he walked away.
The Helvetians continued their march, Cæsar following at a distance, watching for an opportunity of attacking them. At Bibracte, an important city of Gaul (now Mont Beuvray), west of Autun in Burgundy, the opportunity offered itself. Cæsar seized a hill and posted his troops there, and charged the enemy with his cavalry. The Helvetians fiercely repulsed the attack, and poured on the Roman front, but were quite unable to stand against the showers of the Roman pila, which often penetrated several shields at once, and thus fastened them together so that they could not be disentangled. Disconcerted by this unexpected result, the Helvetians were soon discomfited by the sharp attack with swords which instantly followed. Retiring for a while to a hill close by, the barbarians again drew up in battle order, and again descended to combat. Long and fierce was the struggle which followed; the Helvetians fighting like lions till the evening, never once turning their backs on the enemy. This is Cæsar's own report. But barbarian heroism was no match for the regular, well-organized, and highly-trained Roman army, and once more driven back, they withdrew to the hill where had been left their wives and children with the baggage. From this place they ventured to make a last resistance, and they drew up their carts in the form of a deep square, leaving room in the middle for the non-combatants and the baggage. Then mounting their extemporized fort—the so-called Wagenburg—the Helvetian men commenced the fray, even their women and children hurling javelins at the enemy. Not till midnight did the Romans seize and enter on the rude rampart, and when they did the clashing of arms had ceased. All the valiant defenders lay slain at their feet, and the spirit of bold independence of the Helvetians was crushed for ever.
After this fearful disaster the rest of the emigrants, to the number of 110,000, continued their march through Gaul, but lacking both food and capable leaders, and being moreover ill-used by the Gauls, they sent to Cæsar for help. He demanded hostages, and ordered them to return home and rebuild their towns and villages. And, further, he supplied them with food for the journey, and requested the Allobroges to do the same when the Helvetians should arrive in their province. Cæsar admits that this apparent generosity on his part was dictated not by compassion, but by policy. It was to his interest that these barbarians should re-occupy Helvetia, because they would keep watch on the Rhine, and prevent the irruption of the Germans into the country. In their condition now, he calls the Helvetians Associates (fœderati), and not Subjects, and leaves them their own constitution, and, to some extent, their freedom. But they did not relish this forced friendship, which was indeed more like bondage; and when the Celts of Gaul rose in revolt under the noble and beloved Vercingetorix, who had been a friend of Cæsar, they joined their brethren (52 b.c.), and were again vanquished. On the defeat of the Helvetians at Bibracte followed that of the Valisians, in 57 b.c. To establish a direct communication between Central Gaul and Italy, Cæsar took those same measures which Napoleon I. employed long afterwards; he conquered the Valais (by his lieutenant Galba), that he might secure the passage of the Great St. Bernard. A splendid road was formed over Mount Pœninus, and a temple erected to Jupiter Pœninus, where the traveller left votive tablets as a thanksgiving offering after a fortunate ascent.
