The ‘infinite variety’ of Shakespeare’s Roman plays is reflected in the diversity of critical commentary to which they have given rise. Originally published in 1989, the distinguishing feature of this study is that it endeavours to convey a clear idea of the relationship between the characters and events in Shakespeare’s plays and the main narrative sources on which the four Roman plays are based, while simultaneously undertaking a critical analysis of the plays through the perspective of Shakespeare’s Roman worlds, particularly the creation and operation of the value system. Hence these plays are perceived as political plays, histories and tragedies.
