Sprung from one of the oldest and proudest families of Rome, yet nephew by marriage of the peasant-soldier Marius, Cæsar, the high-born democrat, possessed in his own person that combination of qualities which has ever been found most dangerous to the rule of a narrow and selfish oligarchy. The outworn machine which men still called the Roman republic was obviously creaking towards an utter breakdown, and must soon, if the provinces were not to be bled to death by greedy senators, be replaced by the government of a single man, whether that man were called king, or general, or dictator. The only question was who that single man should be. Cæsar felt that he was the man of destiny, foreordained to stand on that awful eminence. He flung out of the Roman forum and senate-house, teeming as they were with squalid intrigues and echoing to the cries of ignoble factions, and at the age of forty set himself to a ten years’ apprenticeship to empire on the banks of the Loire and the Saône, amid the vast forests of Britain or of Gaul. The French historian, Michelet, has finely said: “I would that I could have seen that pale countenance, aged before its time by the revelries of Rome: that delicate and epileptic man, walking at the head of his legions under the rains of Gaul, swimming across our rivers or riding on horseback among the litters in which his secretaries were carried, and dictating five or six letters at once: agitating Rome from the furthest corners of Belgium: sweeping two millions of men from his path and in the space of ten years subduing Gaul, the Rhine and the northern ocean”. At the end of the first three years of Cæsar’s proconsulship (58–56 B.C.) having apparently almost completed the conquest of Gaul, he stood a conqueror on the southern shore of the Straits of Dover, looked across at the white cliffs of Albion, and dreamed of bringing that mysterious island within the circle of Roman dominion. Pretexts for invasion were never lacking to an adventurous proconsul. There were close ties of affinity between many of the northern tribes of Gaul and their British neighbours. Some tribes even bore the same name. The Atrebates of Arras were reflected in the Atrebates of Berkshire; there were Belgæ in Somerset and Wiltshire as well as in Belgium; even men call Parisii were found, strangely enough, in the East Riding of Yorkshire. Then there was also the connexion, whatever may have been its value, between the religion of the continental and the insular Celts. Our information concerning the Druids (chiefly derived from Cæsar himself) is somewhat vague and unsatisfactory, but there is no reason to doubt his statement that the Druidic “discipline” had originated in Britain and had been carried thence into Gaul, and thus any religious element that there may have been in the resistance of the Gallic tribes to Roman domination would look across the channel for sympathy and inspiration.
