Plutarch Galba 8

[1] But at Rome Nymphidius Sabinus was forcing the entire control of affairs into his own hands, not slowly and little by little, but all at once. He thought that Galba was an old man and would hardly have the strength to be carried to Rome on a litter, by reason of his age, for he was in his seventy-third year; moreover, he knew that the soldiery in the city had long been well disposed towards him and were now devoted to him alone, regarding him as their benefactor because of the large gifts which he promised, but Galba as their debtor.

[2] Straightway, therefore, he ordered his colleague Tigellinus to lay down his sword, gave receptions at which he banqueted men who had been consuls or in high command (although he still affixed the name of Galba to his invitations), and instigated many of the soldiers to declare that a deputation ought to be sent to Galba demanding that Nymphidius be made prefect for life without a colleague.

[3]
  Moreover, the senate did much to enhance his honour and power, giving him the title of benefactor, assembling daily at his door, and allowing him the privilege of initiating and confirming all their decrees. This raised him to a still higher pitch of boldness, so that within a short time those who paid court to him were filled, not only with jealousy, but also with fear.

[4] When the consuls provided public servants to carry the decrees of the senate to the emperor, and gave to these the diplomas, as they were called, sealed with their official seal (in order that the magistrates of the various cities, recognising this, might expedite the supply of fresh vehicles for the journey of the couriers), he was vexed beyond all bounds because the decrees had not been sent under his seal and in charge of his soldiers, nay, it is said that he actually thought of proceeding against the consuls, but put away his wrath when they excused themselves and begged for forgiveness.

[5] Again, in his desire to gratify the people, he would not prevent them from beating to death any follower of Nero who fell into their hands. Accordingly, they cast Spiculus the gladiator under statues of Nero that were being dragged about in the forum, and killed him; Aponius, one of Nero’s informers, they threw to the ground and dragged waggons laden with stone over him; and many others, some of whom had done no wrong, they tore in pieces, so that Mauricus, who was justly deemed one of the best men in Rome, told the senate that he was afraid they would soon be searching for a Nero.
