EDDIUS (AEDDI)  , a Kentish choirmaster, summoned by Wilfrid (c . 634-709), bishop of York, to help in organizing church services in Northumbria . He wrote the Life of his patron, and this biography of St Wilfrid is the earliest extant historical work compiled by an Anglo-Saxon author . He is a strong partisan and very credulous, but the Vita Wilfridi is nevertheless invaluable for the period it treats . Its date is little after the first decade of the 8th century, and it was used by Bede in compiling his Historia . See Eddius, Vita Wilfridi (Raine, Historians of Church of York, London, 1879-1894), 14; Bede, Hist . Eccl . (Plummer, Oxford, 1896), in . 2 . I WO lag das Parodies? p . 66 .
