Dr. Lisa Bitel walks me through the ancient Irish Epic, The Tain.  This book is also called "the Irish Iliad".  I'd recommend reading this one AFTER listening to the episode.

A Poem:

The Surfing Irishman

A nadb named dabd did misbehadb

He stole another surfers wadb

You’d think that he could be forgadb
But poor old Dadb is in his gradb.
