What is the narrator point of view in the epic, The Cattle Raid of Cooley?

The narrator in all versions of the Táin Bó Cúailnge sounds like a modern researcher. He is well informed about places, actions, and conversations, but anchors his story in remarks like, "They say it is here that Dubthach chanted," or, "Others say that the bird and the squirrel were both perched on Medb's shoulders." The narrator claims to do nothing more than report, noting the existence of alternate traditions and stories. In place of the help of the muses with their divine knowledge, there is, in one version, the ghost of Fergus or at least the traditions preserved by his descendants. Even when the narrator describes a character's mood, that mood is only what is apparent from either the character's plain admission or actions.
