The Anglo-Saxon Chronicle is very odd sometimes.

The Anglo-Saxon Chronicle is occasionally a highly entertaining document. For instance:

668. In this year Theodore was consecrated as archbishop.

669. In this year King Egbert gave Reculver to the mass-priest Bass, to build a minster in it.

670. In this year Oswiu, king of the Northumbrians, died, and Ecgfrith reigned after him; and Leuthere, Bishop Agilbert's nephew, succeeded to the bishopric over the land of the West Saxons, and Bishop Theodore consecrated him. Oswiu was the son of Æthelfrith, the son of Æthelric, the son of Ida, the son of Eoppa.

671. In this year there was the great mortality of birds.
