Cominius is the chief Roman general, a senator in overall command of the war against the Volscians.
An older man and a good soldier, he is driven to huge enthusiasm by Caius Martius’s exploits, and gives him the honorary name of Coriolanus when he refuses any further reward. He offers the official speech about Coriolanus’s worthiness to be Consul to the Senate, and realizing that speaking nicely is not the younger man’s strong suit also offers to help coach him in speaking to the commons. When Coriolanus is banished he offers to go with him for a month to see that he is well set-up elsewhere, but is rejected. He is sent by Rome to try and bargain with Coriolanus when the latter attacks the city, but is pushed aside. Cominius is an honorable man who is aware that Coriolanus has his faults, but still thinks him ill-used.
