But the suffering people had one consolation at least in the fact that they needed no other punishment of the authors of their sufferings, but saw them slain by one another's hands, and first and most righteously of all, the man who ensnared the soldiery and taught them to expect from the deposition of a Caesar all the good things which he promised them, thus defiling a most noble deed by the pay he offered for it, and turning the revolt from Nero into treachery.
