Durham, 664
Although the Irish monk Tuda was a staunch adherent of the Roman practices, including the computation of the date for Easter, he succeeded Saint Colman as abbot-bishop of Lindisfarne, where the contrary view was held. In this position he governed the entirety of Northumbria. Most of the Celtic usage monks departed with Colman in 664, leaving Tuda to heal the wounds of discord. Tuda signed the deed of dedication of the new Saint Peter's Monastery in Mercia of which the Celtic-born Jaruman was bishop. Even though Tuda, who died of the plague within the first year of his appointment, does not seem to have enjoyed a public cultus, he is listed in some martyrologies.
