Early in the winter of 68, while Nero was still absent in Greece, Galba received overtures from C. Julius Vindex, prefect of the Farther Gaul, for a simultaneous rising. Vindex was himself a Gallico-Roman, scion of a royal house in Aquitania, adopted into the imperial gens; but while he imbibed the pride of a Roman, he retained the impetuous spirit of his ancestors; and the enormities of Nero, aggravated no doubt in his esteem by his exactions in Gaul itself, roused his determination to overthrow him without a view to personal aggrandisement. The time indeed was yet far distant when a foreigner could even conceive the idea of gaining the purple. But he fixed his eyes on Galba, as the ablest of the class from which fortune could make an emperor, and it was with vexation that he found the old chief too cautious to be driven headlong into a revolt, the event of which might seem so doubtful.
Galba indeed had good reason to hesitate. Nero set a price on the head of Vindex, whose designs were speedily revealed to him, and though the forces of the Gaulish province were disposed to follow their chief, the more powerful legions of lower Germany, under Virginius Rufus, were in full march against them. The armies met at Vesontio, and there Vindex and Virginius, at a private interview, agreed to conspire together, but their troops could come to no such understanding; the Virginians attacked the soldiers of Vindex, and almost cut them to pieces. Vindex thereupon, with the haste and levity of his race, threw himself on his sword, and the rebellion seemed for a moment to be crushed.
GALBA IS SALUTED IMPERATOR BY HIS SOLDIERS
But Galba had become alarmed for his own safety. He had received communications from a rebel, all whose acts were well known to the government. He had been urged to proclaim himself emperor, and no refusal on his part could efface the crime of having been judged worthy of such a distinction. Indeed, so at least he pretended, he had already intercepted orders from Nero to take his life, and a plot for his assassination was opportunely detected among a company of slaves presented him by a freedman of the emperor. Thus impelled to provide for his own safety, he called his troops together, and setting before them the images of the tyrant’s noblest victims, harangued them on the state of public affairs. The soldiers saluted him as imperator, but he would only allow himself to be styled Legatus of the senate and the people. He proceeded, however, at once to prorogue all civil business, and provide for immediate war by raising forces, both legionary and auxiliary, from the youth of the province. At the same time he convened the notables of the country, to give perhaps a civil colour to his military enterprise. The Gallic and Germanic legions, now reunited, after the death of Vindex, had offered to raise Virginius to the purple; they conjured him to assume the title of imperator, and inscribed on his busts the names of Cæsar and Augustus. But he steadily refused the honours thrust upon him, erased the obnoxious letters, and at length persuaded his admirers to leave the decision of affairs to the authorities at home. He entered, however, into communication with Galba, who had now, it seems, determined on the attempt, and the news was bruited far and wide that Gaul and Spain had revolted, and that the empire had passed irrevocably from the monster Nero.
At once it appeared how many pretenders to power might exist in the bosom of the provincial camps. The fatal secret of the empire, that a prince might be created elsewhere than at Rome, so long undiscovered, so alien, as was supposed, from the sentiments of the age, was revealed in more than one quarter. Not in Gaul and Spain only, but in Africa and lower Germany, the legions were ready to make an emperor of their own chief. Clodius Macer in the one, Fonteius Capito in the other, were proclaimed by the soldiers. At the same time Salvius Otho, Nero’s ancient favourite, who was weary of his long oblivion on the shores of the Atlantic, declared himself a supporter of Galba, and lent him his own slaves and plate, to swell his retinue and increase his resources. The civil wars had again begun.
