labyrinth

n. maze, complicated network of passages; something confusing or bewildering

In Greek mythology, the Labyrinth (Gk. λαβύρινθος labyrinthos) was an elaborate structure constructed for King Minos of Crete and designed by the legendary artificer Daedalus to hold the Minotaur, a creature that was half man and half bull and which was eventually killed by the Athenian hero Theseus.  Daedalus had made the Labyrinth so cunningly that he himself could barely escape it after he built it. Theseus was aided by Ariadne, who provided him with a fateful thread, literally the "clew," or "clue," to wind his way back again.
