“ And at length, every man that was in any respect eminent or remarkable, they sacrificed to their raging lusts. By these cruelties they so wasted and destroyed the city, that above one half of its inhabitants ran away and left it.
And although the Lacedæmonians saw the city thus spoiled and ruined, yet they laughed in their sleeves, having no desire it should recover its strength any more, as was very evident by the many convincing arguments. For they made a decree—That all the fugitives from Athens, in every part of Greece, should be carried back bound to the tyrants ”

“ But not long after, when they resolved to be lawless, and set up an arbitrary power, they sent for a garrison from the Lacedæmonians, upon the pretence that they would mould all things in the government to the advantage of their interest. For they knew very well, that, without a foreign force, they could not execute those slaughters and butcheries they designed, for that all would as one man rise up against them in their own defence. ”

“ After they had executed him, the thirty, upon false accusations, put to death several others of the rich men whom they had written down in a list, and when they were dead, seized upon all they had. Among whom was Niceratus, the son of Nicias the general, who was formerly sent against the Syracusans. ”
