Being roused at last by numerous proclamations of Vindex, treating him with reproaches and contempt, he in a letter to the senate exhorted them to avenge his wrongs and those of the republic; desiring them to excuse his not appearing in the senate house, because he had got cold. But nothing so much galled him, as to find himself railed at as a pitiful harper, and, instead of Nero, styled Aenobarbus: which being his family name, since he was upbraided with it, he declared he would resume it, and lay aside the name he had taken by adoption. Passing by the other accusations as wholly groundless, he earnestly refuted that of his want of skill in an art upon which he had bestowed so much pains, and in which he had arrived at such perfection; asking frequently those about him, "if they knew any one who was a more accomplished musician?" But being alarmed by messengers after messengers of ill news from Gaul, he returned in great consternation to Rome. On the road, his mind was somewhat relieved, by observing the frivolous omen of a Gaulish soldier defeated and dragged by the hair by a Roman knight, which was sculptured on a monument; so that he leaped for joy, and adored the heavens. Even then he made no appeal either to the senate or people, but calling together some of the leading men at his own house, he held a hasty consultation upon the present state of affairs, and then, during the remainder of the day, carried them about with him to view some musical instruments, of a new invention, which were played by water;Suetonius calls them organa hydraulica, and they seem to have been a musical instrument on the same principle as our present organs, only that water was the inflating power. Vltruvius (iv. i.) mentions the instrument as the invention of Ctesibus of Alexandria. It is also well described by Tertullian, De Aniza, c. xiv. The pneumatic organ appears to have been a later improvement. We have before us a contorniate medallion, of Caracalla, from the collection of Mr. W. S. Bohn, upon which one or other of these instruments figures. On the obverse is the bust of the emperor in armour, laureated, with the inscription M. AURELIUS ANTONINUS PIUS AUG. BRIT. (his latest title). On the reverse is the organ; an oblong chest with the pipes above, and adrapedfigure on each side. exhibiting all the parts, and discoursing upon the principles and difficulties of the contrivance; which, he told them, he intended to produce in the theatre, if Vindex would give him leave.

Soon afterwards, he received intelligence that Galba and the Spaniards had declared against him; upon which, he faiited, and losing his reason, lay a long time speechless, and apparently dead. As soon as he recovered from this state of stupefaction, he tore his clothes, and beat his head, crying, " It is all over with me !" His nurse endeavoring to comfort him, and telling him that the like things had happened to other princes before him, he replied, " I am beyond all example wretched, for I have lost an empire whilst I am still living." He, nevertheless, abated nothing of his usual luxury and inattention to business. Nay, on the arrival of good news from the provinces, he, at a sumptuous entertainment, sung with an air of merriment some jovial verses upon the leaders of the revolt, which were made public; and accompanied them with suitable gestures. Being carried privately to the theatre, he sent word to an actor who was applauded by the spectators, " that he had it all his own way, now that he himself did not appear on the stage."

At the first breaking out of these troubles, it is believed that he had formed many designs of a monstrous nature, although conformable enough to his natural disposition. These were to send new governors and commanders to the provinces and the armies, and employ assassins to butcher all the former governors and commanders, as men unanimously engaged in a conspiracy against him; to massacre the exiles in every quarter, and all the Gaulish population in Rome; the former lest they should join the insurrection; the latter as privy to the designs of their countrymen, and ready to support them; to abandon Gaul itself, to be wasted and plundered by his armies; to poison the whole senate at a feast; to fire the city, and then let loose the wild beasts upon the people, in order to impede their stopping the progress of the flames. But being deterred from the execution of these designs, not so much by remorse of conscience, as by despair of being able to effect them; and judging an expedition into Gaul necessary, he removed the consuls from their office, before the time of its expiration was arrived; and in their room assumed the consulship himself without a colleague, as if the fates had decreed that Gaul should not be conquered, but by a consul. Upon assuming the fasces, after an entertainment at the palace, as he walked out of the room leaning on the arms of some of his friends, he declared, that as soon as he arrived in the province, he would make his appearance amongst the troops, unarmed, and do nothing but weep: and that, after he had brought the mutineers to repentance, he would, the next day, in the public rejoicings, sing songs of triumph, which he must now, without loss of time, apply himself to compose.

In preparing for this expedition, his first care was to provide carriages for his musical instruments and machinery to be used upon the stage; to have the hair of the concubines he carried with him dressed in the fashion of men; and to supply them with battle-axes, and Amazonian bucklers. He summoned the city-tribes to enlist; but no qualified persons appearing, he ordered all masters to send a certain number of slaves, the best they had, not excepting their stewards and secretaries. He commanded the several orders of the people to bring in a fixed proportion of their estates, as they stood in the censor's books; all tenants of houses and mansions to pay one year's rent forthwith into the exchequer; and with unheard-of strictness, would receive only new coin of the purest silver and the finest gold; insomuch that most people refused to pay, crying out unanimously that he ought to squeeze the informers, and oblige them to surrender their gains.
