In the mean time fresh messengers arrived at short intervals from Rome, to inform Nero of the progress of the rebellion. The news was that Vindex was gaining strength every day, and was issuing proclamations to the people calling upon them everywhere to rise and throw off the ignoble yoke of oppression which they were enduring. In these proclamations the emperor was called Brazenbeard, and designated as a "wretched fiddler." These taunts excited Nero's ire. He wrote to the Senate at Rome calling upon them to adopt some measures for putting down this insolent rebel, and having dispatched this letter, he seemed to dismiss the subject from his mind, and turned his attention anew to his dancing and acting. His mind was, however, soon disturbed again, for fresh messengers continued to come, each bringing reports more alarming than those of his predecessor. The rebellion was evidently gaining ground. Nero was convinced that something must be done. He accordingly broke away, though with great reluctance, from his amusements at Naples, and proceeded to Rome. On his arrival at the capital he called a council of some of his principal ministers of state, and after a short consultation on the subject of the rebellion--in which, however, nothing was determined upon--he proceeded to produce some newly-invented musical instruments which he had brought with him from Naples, and in which he was greatly interested. After showing and explaining these instruments to the councilors, he promised them that he would give them the pleasure before long of hearing a performance upon them, on the stage,--"provided," he added jocosely, "that this Vindex will give me leave." The councilors at length withdrew, and Nero remained in his apartment. On retiring to rest, however, he found that he could not sleep. His thoughts were running on the musical instruments which he had been showing, and on the pleasure which he anticipated in a public performance with them. At length, at a very late hour, he sent for his councilors to come again to his apartment. They came, full of excitement and wonder, supposing that they were thus suddenly summoned on account of some new and very momentous tidings which had been received from Gaul. They found, however, that Nero only wished to give some further account of the instruments which he had shown them, and to ask their opinions of certain improvements which had occurred to him since they went away. Nero did not, however, remain very long in this state of insane and stupid unconcern; for on the evening of the following day a courier arrived from the north with the appalling intelligence that Vindex had made himself master of Gaul, and that Galba, the most powerful general in the Roman army, had joined the insurrection with all the legions under his command, and that he was now advancing toward Rome at the head of his armies with the avowed purpose of deposing Nero, and making himself emperor in his stead.
