This book contains essays on the seven surviving tragedies attributed to Aeschylus (including Prometheus, which is of doubtful authenticity). It is intended primarily as a readable introduction for A-level students of Classical Civilisation and Ancient History. It should be of interest also to students of other disciplines and to the non-specialist reader. The emphasis throughout is on Aeschylus’ tragic thinking and on the dramatic structure of the plays. A brief concluding chapter attempts to draw together what has been said in the essays on the individual plays. The aim of the book is to help readers to understand why Aeschylus is still worth reading, or going to see in the theatre in the 21st century, and to defend the earlier plays against the view that they are in some respects immature in structure and thought.
