Sophocles brought a unique perspective to Greek tragedy by emphasizing complex character development and moral dilemmas, often exploring themes of humanity and fate. His use of dramatic irony and rich theatrical elements deepened the audience's emotional connection to the characters and their struggles. In plays like "Oedipus Rex," Sophocles examined the consequences of hubris and the inescapability of fate, challenging viewers to reflect on their own lives. His innovations in staging and character depiction set new standards in theater, influencing both his contemporaries and future generations of playwrights.
