William Hunt, Dictionary of National Biography… (1895)
“ Although the murder of Oswin is a blot on Oswy's memory, he appears to have been a religious man, sincerely anxious for the spread of Christianity. He had to contend with many difficulties, and overcame them triumphantly. Northumbria, which at his accession seemed to lie at the mercy of its great enemy, Penda of Mercia, was raised by him to a position of supremacy equal to that which it had held under Eadwine. Besides the overthrow of Penda and the increase of Oswy's power consequent upon his victory, his reign presents three characteristics of special importance. ”
