As far as I know, Shakespeare's group of Roman plays are Antony and Cleopatra, Coriolanus and Julius Caesar!. I'd include Titus Andronicus in that group because of the similar thematic elements, but that's just my opinion!. The first three are the commonly agreed upon Roman group!.Www@QuestionHome@Com
