"Tochmarc Étaíne" ("The Wooing of Étaín") tells first of the conception of Aengus through the adultery of the Dagda and Boann, and how Aengus won the residence of the "Brú na Bóinne" from Boann's husband Elcmar. It goes on to tell of the various lives of Étaín, wife of Midir, who is turned into a fly and driven away by Midir's jealous first wife Fuamnach. She becomes the companion of Aengus in insect form before Fuamnach once again drives her away, and she is swallowed by a mortal woman and reborn as her daughter. Her beauty attracts the attention of the High King, Eochaid Airem, who marries her, but ultimately Midir wins her back by magic and trickery.
