"No man knows much," Galen interrupted. "Marcia's soul may be all the soul Commodus has! If she should grow sick of him—!"

"She grew sick long ago," said Cornificia. "But she is forever thinking of her Christians and knows no other way to protect them than to make Commodus love her. Ugh! It is like the story of Andromeda. Who is to act Perseus?"

(In the fable, Andromeda had to be chained to a cliff to be devoured by a monster, in order to save her people from the anger of the god Poseidon. Perseus slew the monster.)

"There are thirty thousand ways of killing," Pertinax repeated, "but if we kill one monster, four or five others will fight for his place, unless, like Perseus, we have the head of a Medusa with which to freeze them into stone! There is no substitute for Commodus in sight. The only man whose face would freeze all rivals is Severus the Carthaginian!"

"We are none of us blind," said Cornificia.

"You mean me? I am too old," answered Pertinax. "I don't like tyranny, and people know it. It is something they should not know. An old man may be all very well when he has reigned for twenty years and men are used to him, and he used to the task, as was Augustus; but an old man new to the throne lacks energy. And besides, they would never endure a man whose father was a charcoal-seller, as mine was. I have made my way in life by looking at facts and refusing to deceive myself; with the exception of that, I have no especial wisdom, nor any unusual ability."

"If wisdom were all that is needed," said Sextus, "we should put good
Galen on the throne!"

"He is too old and wise to let you try to do it!" Galen answered. "But you spoke about the head of a Medusa, Pertinax, and mentioned Lucius Septimius Severus. He commands three legions at Caruntum in Pannonia. (Roughly speaking, the S.W. portion of modern Hungary whose frontiers were then occupied by very warlike tribes.) If there is one man living who can freeze men's blood by scowling at them, it is he! And he is not as old as you are."

"I have thought of him only to hate him," said Pertinax. "He would not follow me, nor I him. He is one of three men who would fight for the throne if somebody slew Commodus, although he would not run the risk of slaying him himself, and he would betray us if we should take him into confidence. I know him well. He is a lawyer and a Carthaginian. He would never ask for the nomination; he is too crafty. He would say his legions nominated him against his will and that to have disobeyed them would have laid him open to the punishment for treason. (This is what Severus actually did, later on, after Pertinax's death.) The other two are Pescennius Niger, who commands the legions in Syria, and Clodius Albinus who commands in Britain. We must find a man who can forestall all three of them by winning, first, the praetorian guard, and then the senate and the Romans by dint of sound reforms and justice."

"You are he! Rome trusts you. So does the senate," said Cornificia.
"Marcia trusts me. The praetorian guard trusts her. If I can persuade
Marcia that her life is in danger from Commodus—"
