'Abbo' - Abbo of Fleury (d. 1004), one of the leading scholars of the second half of the tenth century, wrote the Passio Sancti Eadmundi martyris which Ælfric translates here. He was born c. 940 and became an oblate at Fleury. He was later educated in Orléans and Paris. In 985, he visited Ramsey at the request of Dunstan and the monks of Ramsey, but returned home in autumn 987 to become abbot of Fleury. He was murdered in 1004 while on an expedition to reform a dependent priory in Gascony, and was considered a martyr. There is a vita by one of his pupils, Aimo.
