Upon the Council withdrawing in this way without venturing any objection, and the rest of the citizens making no movement, the Four Hundred entered the council chamber, and for the present contented themselves with drawing lots for their Prytanes, and making their prayers and sacrifices to the gods upon entering office, but afterwards departed widely from the democratic system of government, and except that on account of Alcibiades they did not recall the exiles, ruled the city by force;
