it this way, but Plutarch is only repeating a legend and in my opinion he could have worked it out better at this point. Shakespeare seems to have started in this direction and then never wrote or dropped out the crucial scene.
It is only that missing scene that can explain what happens next. Coriolanus makes his way, in disguise, to the house of Tullus Aufidius, who is there presiding over a feast to the Volscian nobles, and reveals himself as a suppliant. He tells Aufidius he has nothing left but his name:
The cruelty and envy of the people,
Permitted by our dastard nobles, who
Have all forsook me, hath devoured the rest.
- Act IV, scene v, lines 78-80
Why "dastard nobles?" How have they "forsook" him? Only that missing scene would make this plain and account for the colossal bitterness of Coriolanus during the remainder of the play, against not only the plebeians, but the entire city.
The Coriolanus legend up to this point, by the way, bears a suspicious resemblance to the tale of Themistocles, a famous Athenian who was actually a contemporary of Coriolanus (except that Themistocles is a historical character and Coriolanus is not).
Themistocles was the moving spirit behind the Athenian-led Greek victory over the Persians in 480 b.c. (thirteen years after the supposed capture of Corioli). After the defeat, however, when Athens was secure, Themistocles' growing pride offended the Athenians. About 472 b.c. he was exiled from the city. In exile, evidence of treason was found against him and he had to make his way to Persia itself as the only place he could be safe.
On his way there he passed through the city of a man who was his personal enemy-Admetus, King of the Molossians. (Molossia was later known as Epirus and is, in modern times, called Albania.)
Themistocles came to Admetus in disguise and appealed to him as a fugitive, just as Coriolanus appealed to Aufidius.
Here the stories part company, however. Themistocles was accepted by Admetus and finally made his way to Persia, where he lived out the remainder of his life. He never took any actual action against Athens.
Coriolanus did not wish escape. He wished revenge.
Joined with Aufidius...
Aufidius accepts Coriolanus' help joyfully. In fact, he offers him generalship over half the army, for what may seem to us perfectly valid reasons. It may seem odd to take the chance of turning over half his forces to someone who until recently had been the chief enemy of the Volscians, but by now Aufidius must know Coriolanus' character well. He must know that Coriolanus has in his mind room for nothing but rage. If the rage is now turned against Rome, the breach between man and city will be made permanent. Coriolanus will have to continue aiding the Volscians, placing his fighting ability and his inside knowledge of Rome at Volscian disposal. And then, when Rome is utterly defeated and wiped out, Coriolanus can be taken care of.
Rome, meanwhile, is in a temporary state of utter peace and the tribunes congratulate themselves at having brought things to such a happy conclusion. The bad news comes soon enough, however. A messenger dashes in saying:
It is spoke freely out of many mouths,
How probable I do not know, that Marcius,
Joined with Aufidius, leads a power 'gainst Rome,
- Act IV, scene vi, lines 65-67
Perhaps this is why the missing scene is missing (either taken out or never written). For the missing scene to have worked, there would have had to be news of a Volscian advance, followed by a patrician refusal to abandon the city, so that Coriolanus would have had to join the enemy in a rage. But then he would merely be joining a marching army as a hanger-on.
This way, the Volscians don't move until Coriolanus joins them, and the news arrives that not only is the enemy approaching but the exiled Coriolanus is at their head. So, for the sake of this added drama, the missing scene is removed. It means that the meeting between the Roman and the Volsce is made irrelevant and Coriolanus' desertion to the Volscians and his anger against the "dastard nobles" left inadequately motivated. In this case, apparently, Shakespeare had his choice of two lines of development and did not manage to make a clear decision.
... cowardly nobles.. .
The failure to make a clear decision between the two courses of development haunts this sixth scene of the fourth act. At first the patricians seem rather exultant about Coriolanus' assault. Cominius says of the Vol-scians:
