After his death, the soldiers took Mizentius, a certain Armenian, and made him emperor ; but after a few days, Constantine, son of the deceased Constane, overcame Mizentius and the murderers of his father, and condemned them to a disgraceful death. In these days days died Mahomet the false prophet, of whom we have spoken before, and he was buried in helL Constantine, after attaining the Roman empire, destroyed the heresy of the Monothelites. In the year of grace 670, Adeodatus sat in the Roman chair four years, two months, and five days ; after which the see remained vacant for four months and fifteen days. The same year, Constantine, son of Constane, attained the Roman empire, and reigned seventeen years. He restored the churches which had been overthrown from the times of Heraclius his great-grandfather ; and laboured for the subversion of the heresy of the Monothelites and those who adhered to it. The same year died Oswy, the august king of the Northumbrians, worn out with disease and old age, and was buried in the church at Streneshale, where king Eadwin was buried before him. His son Egfrid reigned in his stead fifteen years. Now Oswy was the son of Athelferth, who was the son of Athelric, who was the son of Ida, the first king of the Northumbrians of the race of the Angles. A battle of birds. In the year of grace 671, there was an extraordinary battle in England among the birds, insomuch that many thousands were found killed, and it seemed that the foreign birds were put to flight.
