"Nor can he be easily got rid of," remarked Daedalus the tribune. "He goes to and fro from the palace through underground tunnels. Men sleep in his room who are all involved with him in cruelties and infamy, so they guard him carefully. Besides, whoever tried to murder him would probably kill Paulus by mistake! The praetorian guard is contented, being well paid and permitted all sorts of privileges. Who can get past the praetorian guard?"

"Any one!" said Pertinax. "The point is not, who shall kill Commodus? But who shall be raised in his place? There are thirty thousand ways to kill a man. Ask Galen!"

Old Galen laughed at that.

"As many ways as there are stars in heaven; but the stars have their say in the matter! None can kill a man until his destiny says yes to it. Not even a doctor," he added, chuckling. "Otherwise the doctors would have killed me long ago with jealousy! A man dies when his inner man grows sick and weary of him. Then a pin-prick does it, or a sudden terror. Until that time comes you may break his skull, and do not more than spoil his temper! As a philosopher I have learned two things: respect many, but trust few. But as a doctor I have learned only one thing for certain: that no man actually dies until his soul is tired of him."

"Whose soul should grow sick sooner than that of Commodus?" asked
Sextus.

"Not if his soul is evil and delights in evil—as his does!" Galen retorted. "If he should turn virtuous, then perhaps, yes. But in that case we should wish him to live, although his soul would prefer the contrary and leave him to die by the first form of death that should appear—in spite of all the doctors and the guards and tasters of the royal food."

"Some one should convert him then!" said Sextus. "Cornificia, can't Marcia make a Christian of him; Christians pretend to oppose all the infamies he practises. It would be a merry joke to have a Christian emperor, who died because his soul was sick of him! It would be a choice jest—he being the one who has encouraged Christianity by reversing all Marcus Aurelius' wise precautions against their seditious blasphemy!"

"You speak fanatically, but you have touched the heart of the problem," said Cornificia. "It is Marcia who makes life possible for Commodus— Marcia and her Christians. They help Marcia protect him because he is the only emperor who never persecuted them, and because Marcia sees to it that they are free to meet together without having even to bribe the police. There is only one way to get rid of Commodus: Persuade Marcia that her own life is in danger from him, and that she will have a full voice in nominating his successor."

"Probably true," remarked Pertinax. "Whom would she nominate? That is the point."

"It would be simpler to kill Marcia," said Daedalus. "Thereafter let things take their course. Without Marcia to protect him—"
