Three plays. One is fair, one is passable, one is unforgivably weak. None rivals his verse.
The Unicorn from the Stars, at three acts, is the longest. Mostly the work of Lady Gregory, is an uneven treatment of religion, politics, and work. It has the best lines, but it is a mess.
The second piece and perhaps the most coherent, Cathleen Ni Houlihan, is a one act political allegory set in the rebellion of 1798. Ireland, rendered as an old woman who has lost her land, and demands total commitment. Indeed, she demands sacrifice: "If anyone would give me help he must give me himself, he must give me all."
The Old Woman's call for martyrdom echoes Yeats's more ambiguous act of remembrance in Easter 1916:
"They shall be remembered for ever,
They shall be alive for ever,
They shall be speaking for ever,
The people shall hear them for ever."
The final offering, The Hourglass, can be ignored all together.
