EDDIUS or AEDDI, a Kentish choirmaster, was employed by Wilfrid (c. 634-709), bishop of York, to organize services in Northumbria. His Life of Wilfrid is the earliest extant work of an Anglo-Saxon author. It is invaluable for its period, though strongly partisan in feeling, and was used by Bede for his His toria.
