Bricriu’s feast : a comedy in three acts
Here’s good read for a cold and rainy day: it’s a satirical play written by Eimar O’Duffy in 1919.

Bricriu’s feast : a comedy in three acts, with an epilogue (1919). This play is very funny, taking a light handed approach to the importance of The Champion’s Portion, and a timely reminder for Ireland in the early twentieth century to keep her wits about her – no spoilers!
Biography for Eimar O’Duffy.
In Sir Gawain and the Green Knight – New translation by Benedict Flynn (audio CD available from here), we learn that:
“The beheading game, the main plot (of SirG&GK), has its roots in ancient pagan folklore. The earliest version is an eighth century Irish story, Briciu’s Feast, where Gawain’s role is played by the Irish hero Cuchulain.
Maybe before, or after!, reading the comedy, a translation of the early Irish story would be enjoyed, and this is found at Flan Bricriu – Bricriu’s Feast translated by George Henderson.
