The Bacchae by Euripides (408–406 b.c.e.). “Gods should be exempt from human passions,” says Cadmus, but such is not the case for Dionysus in one of the goriest Greek tragedies. Dionysus seeks revenge on Cadmus’s grandson Pentheus, a Theban king who has tried to quash the Bacchus cult in Thebes. Dionysus seduces Pentheus into witnessing a Bacchanalian orgy, where he is torn to pieces by the revelers, including his own mother.
