The most famous of Sophocles's tragedies are those concerning <strong><a href="http://www.shelfari.com/characters/Oedipus" rel="nofollow">Oedipus</a> </strong>and <strong><a href="http://www.shelfari.com/characters/Antigone" rel="nofollow">Antigone</a></strong>: these are often known as the <a href="http://www.shelfari.com/series/Theban-plays" rel="nofollow">Theban plays or The Oedipus Cycle, although each play was actually a part of different trilogy, the other members of which are now lost.
