The version known as the Brut Tysilio, attributed to the 7th-century Welsh saint Tysilio, became more widely known when its text was published in The Myvyrian Archaiology of Wales, a once-influential collection of Welsh literary material whose credibility has suffered due the involvement of the antiquarian forger Iolo Morganwg, in 1801-1807.
Confusion has arisen with Sulinus or Sulien, the Breton saint of Cornouaille and Domnonée, East Brittany (feast: 1 October) Furthermore the legend of Tysilio (or Suliau), whose feast is on 8 November, was used for the Breton saint.
Walter's name is attached to the Brut Tysilio, a variant of the Welsh chronicle Brut y Brenhinedd.
