York diocese was then divided in 678 by Archbishop Theodore of Canterbury, forming a bishopric for the country between the Rivers Aln and Tees, with a seat at Hexham.
This gradually and erratically merged back into the bishopric of Lindisfarne.
Eleven bishops of Hexham followed St. Eata, of which six were saints.
A period of disorder followed the Danish devastations, after which Hexham monastery was reconstituted in 1113 as a priory of Austin Canons, which flourished until its dissolution under Henry VIII.
Meantime the bishopric had been merged in that of Lindisfarne, which latter see was removed to Chester-le-Street in 883, and thence to Durham in 995.
