The Resurrection has characters called the Jew, the Greek and the Syrian. They debate the resurrection of Christ as it is happening. The action is topped and tailed by songs that knock spots off everything in between.
Purgatory has the reputation of being Yeats' best play. Two men- an old beggar and his son- fetch up outside a haunted house. It's melodramatic and grim.
The Herne's Egg is bonkers. It's like Monty Python and the Holy Grail- only shot through with a vein of authentic pagan mysticism.
