Plutarch Galba 2

[1] It was Nymphidius Sabinus, prefect of the court guard along with Tigellinus, as I have already stated, ¹ who, when Nero’s case was altogether desperate, and it was clear that he was going to run away to Egypt, persuaded the soldiery, as though Nero were no longer there but had already fled, to proclaim Galba emperor,

[2] and promised as largess seventy-five hundred drachmas apiece for the court, or praetorian, guards, as they were called, and twelve hundred and fifty drachmas ² for those in service outside of Rome, a sum which it was impossible to raise without inflicting ten thousand times more evils upon the world than those inflicted by Nero.

[3] This promise was at once the death of Nero, and soon afterwards of Galba: the one the soldiers abandoned to his fate in order to get their reward, the other they killed because they did not get it. Then, in trying to find someone who would give them as high a price, they destroyed themselves in a succession of revolts and treacheries before their expectations were satisfied. Now, the accurate and circumstantial narration of these events belongs to formal history; but it is my duty also not to omit such incidents as are worthy of mention in the deeds and fates of the Caesars.
