Book 2
Chapter 54: What Vengeance overtook those who on Account of the Oracle raised the Persecution
But why need I longer dwell on these lamentable events, and the general sorrow which in consequence pervaded the world? The perpetrators of this dreadful guilt are now no more: they have experienced a miserable end, and are consigned to unceasing punishment in the depths of the lower world. They encountered each other in civil strife, and have left neither name nor race behind. And surely this calamity would never have befallen them, had not that impious deliverance of the Pythian oracle exercised a delusive power over them.
