Kathy Eden invites us on a journey where she clarifies, borrows and develops the terms used in Aristotle's Poetics. It is a journey which starts from the Attic rhetoric of the 5th century BC passing through Stoic philosophy of the Romans and Scholasticism of the Fathers of the early Christian centuries, until the Renaissance; journeying through Hamlet and Philip Sidney's An Apology for Poetry, which is perhaps the most important treatise on theater regarding the 16th century.
