If you read the Annals of Tigernach, you will find that Máel Brigte mac Mothlachán killed Rogallach mac Uatach, King of Connacht, in battle, because the Uí Briúin tribe had been encroaching on the territory of the Corco Cullu, and so it was one of those normal murders. However, if you read the renowned and beloved Geoffrey Keating, you will discover that no, Rogallach, riding his white horse, was killed by servants, after a dispute about who had actually killed a deer, but before that Rogallach had been living a version of Oedipus, sleeping with his daughter, who had been, as an infant sent out to die, but a huntsman saved her, and then later her dad met her and incestuous relations followed. We do talk about Connacht, and Rogallach, and Máel Brigte mac Mothlachán, but really what Anne is concerned about is the inability of some historians to tell the difference between history and storytelling, and Michelle, bless her heart, is driven to sputtering outrage by the inability of some scholars to tell you where they found the stuff, history or story, either one.
