Kazuhiko Tange, "Greek Tragedy" - Recommended introductory book to learn the depth of Greek tragedy.
In this work, you will first learn about the origins of Greek tragedy and its flow in the introduction.
From there, the flow of the book, in chronological order, examines the depth of Greek tragedy through the works of Aeschylus, Sopocles, and Euripides, the major figures in Greek tragedy. I appreciated this because it explains very clearly how the content of tragedy changed over time.
Greek tragedies are well-known by name, but their contents are not well known. This is a recommended introductory book to learn the depth of Greek tragedy.
