republished most recently with a new introduction by Thomas F.X. Noble in 2000. Included among his letters and dated to 716 is one to Abbess Edburga of Minster-in-Thanet containing the Vision of the Monk of Wenlock. This otherworld vision describes how a violently ill monk is freed from his body and guided by angels to a place of judgment, where angels and devils fight over his soul as his sins and virtues come alive to accuse and defend him. He sees a hell of purgation full of pits vomiting flames. There is a bridge over a pitch-black boiling river. Souls either fall from it or safely reach the other side cleansed of their sins. This monk even sees some of his contemporary monks and is told to warn them to repent before they die. This vision bears signs of influence by the Apocalypse of Paul, the visions from the Dialogues of Gregory the Great, and the visions recorded by Bede. Sermons Some fifteen preserved sermons are traditionally associated with Boniface, but that they were actually his is not generally accepted. Grammar and poetry Early in his career, before he left for the continent, Boniface wrote the , a grammatical treatise presumably for his students in Nursling. Helmut Gneuss reports that one manuscript copy of the treatise originates from (the south of) England, mid-eighth century; it is now held in Marburg, in the Hessisches Staatsarchiv. He also wrote a treatise on verse, the , and a collection of twenty acrostic riddles, the , influenced greatly by Aldhelm and containing many references to works of Vergil (the Aeneid, the Georgics, and the Eclogues). The riddles fall into two sequences of ten poems. The first, ('on the virtues'), comprises: 1. /truth; 2. /the Catholic faith; 3. /hope; 4. /compassion; 5. /love; 6. /justice; 7. /patience; 8. /true, Christian peace; 9. /Christian humility; 10. /virginity. The second sequence, ('on the vices'), comprises: 1. /carelessness; 2. /hot temper; 3. /greed; 4. /pride; 5. /intemperance; 6. /drunkenness; 7. /fornication; 8. /envy; 9. /ignorance; 10. /vainglory. Three octosyllabic poems written in clearly Aldhelmian fashion (according to Andy Orchard) are preserved in his correspondence, all composed before he left for the continent. Additional materials A letter by Boniface charging Aldebert and Clement with heresy is preserved in the records of the Roman Council of 745 that condemned the two. Boniface had an interest in the Irish canon law
