From the time when the great diocese of York was broken up in the year 681, its history has had no bearing upon that of the churches of Cumbria or Lothian. The diocese of Lindisfarne, however, extended to the Firth of Forth; and about this time the monastery of Tyninghame, at the mouth of the river Tyne in East Lothian, must have been founded within it by Balthere the anchorite. Simeon of Durham, in his History of the Kings, records in the year 756 the death of Balthere the anchorite, and, in his History of the Church of Durham, he adds ‘in Tiningaham.’[426] He is popularly known in the district as St. Baldred of the Bass. By Bower St. Baldred is connected with Kentigern, and said to have been his suffragan bishop; and he reports a tradition that, a contest having arisen between the parishioners of the three churches of Haldhame, Tyninghame, and Lyntoun, in Lothian, for the possession of his body, and arms having been resorted to, they were at night overcome with sleep, and on awaking found three bodies exactly alike, one of which was buried in each church. This sufficiently connects St. Baldred with Tyninghame; and Alcuin, who wrote in the eighth century, as clearly connects Balthere with the Bass.[427] He was thus removed from Kentigern’s time by more than a century, was in reality an anchorite, and connected, not with the British diocese of Cumbria, but with the Anglic see of Lindisfarne. This diocese contained the territory extending from the Tyne to the Tweed, including the district of Teviotdale; and we learn from the anonymous history of Cudberct that its possessions beyond the Tweed consisted of the districts on the north bank from the sea to the river Leader, and the whole land which belonged to the monastery of St. Balthere, which is called Tyningham, from the Lammermoors to the mouth of the river Esk.[428] Beyond this western boundary the church of Lindisfarne possessed the monastery of Mailros with its territory; Tighbrethingham, which cannot be identified with any certainty; Eoriercorn or Abercorn, on the south shore of the Firth of Forth, and the monastery in which Trumuini had his seat when he ruled over the province of the Picts during their subjection to the Angles, and from which he fled after the disastrous battle of Dunnichen; and Edwinesburch, or Edinburgh, where the church dedicated to St. Cuthbert still bears his name.[429] The history of the church of Hagustald, or Hexham, will be found to have an important bearing upon that of one of the more northern churches.
