The Birth of Tragedy: Out of the Spirit of Music (Penguin Classics) by Friedrich Nietzsche, Michael Tanner, Shaun Whiteside

The first book by the author of the classic philosophical text Beyond Good and Evil.
 
The youthful faults of this work were exposed by the author himself in the brilliant Attempt at a Self-Criticism, which he added to the new edition of 1886. But the book, whatever its excesses, remains one of the most relevant statements on tragedy ever penned. It exploded the conception of Greek culture that was prevalent down through the Victorian era, and it analyzed themes developed in the twentieth century by classicists, existentialists, psychoanalysts, and others.
