100. Coriolanus begins - even to the altitude of his virtue

We begin Cariolanus, and meet Martius, a proud Roman patrician, who later becomes Cariolanus.  He confronts a band of rebellious plebians and expresses his contempt for them.  The civil strife is apparently interrupted by pending war with the Volscians, whose leader is a frenemy of Martius. He goes to war, but the new tribunes stay behind and begin a plot against Martius.
