Every one knows the story of the tyrannicide who, being caught before he had accomplished his task, and being tortured by Hippias to make him betray his accomplices, named the friends of the tyrant who stood around, and every one to whom he knew the tyrant’s safety was especially dear. As the tyrant ordered each man to be slain as he was named, at last the man, being asked if any one else remained, said, “You remain alone, for I have left no one else alive to whom you are dear.” Anger had made the tyrant lend his assistance to the tyrant-slayer, and cut down his guards with his own sword. How far more spirited was Alexander, who after reading his mother’s letter warning him to beware of poison from his physician Philip, nevertheless drank undismayed the medicine which Philip gave him!
