to adduce a few instances from them. For Alcmæon of Crotona having said, "It is easier to guard against a man who is an enemy than a friend," Sophocles wrote in the Antigone:
"For what sore more grievous than a bad friend?"
And Xenophon said: "No man can injure enemies in any other way than by appearing to be a friend."
And Euripides having said in Telephus:
