The said Birinus went thither by the command of Pope Honorius; and he was bishop there to the end of his life. Oswald (age 30) also this year succeeded to the government of the King Northumbrians, and reigned nine winters. The ninth year was assigned to him on account of the heathenism in which those lived who reigned that one year betwixt him and Edwin.
