About this source

What it is

This book, written by Sigmund Freud and published around 1900, introduces his theory of the unconscious mind and dream interpretation. In it, Freud discusses Sophocles' play Oedipus Rex as part of his developing theory of the 'Oedipus complex', one of his most famous psychological ideas.

Why it matters

Freud's reading of Oedipus Rex became one of the most influential modern interpretations of Sophocles' play, showing how an ancient tragedy could be reinterpreted through a completely new lens centuries later. It reveals how works from the distant past continue to shape and be shaped by new ways of thinking.

Look closer

  • Why might a psychologist in 1900 be interested in a Greek tragedy written over two thousand years earlier?
  • Does Freud's interpretation tell us more about Sophocles' own ideas, or about Freud's own time and theories?
  • What might be lost or changed when a story is reinterpreted through a new framework like psychoanalysis?
