 The reports of Aldfrith's death in the Irish annals call him Aldfrith son of Oswiu, but some of these are glossed by later scribes with the name Flann Fína mac Ossu. A collection of wisdom literature attributed to Flann Fína, the Briathra Flainn Fhina Maic Ossu, has survived, though the text is not contemporary with Aldfrith as it is in Middle Irish, a form of Irish not in use until the 10th century.
