I ve made a few changes to this page I removed the original language the place for that is on Wikisource I ve added an introduction outlining some of the problems involved in constructing a chronology of Anglo Saxon England though I feel more needs to be said on how and for what purpose annals and chronicles were written I also removed the reference to the 1917 article that was based heavily on Historia Brittonum which has received a mammoth of attention since then especially by David Dumville I m not saying this isn t important but one wouldn t cite an article written in 1917 as the main source for a Wikipedia article on the structure of the atom such a reference belongs in a section on changes in interpretations Such historiography is sadly missing in many Wikipedia history articles If anyone feels the chanes I have made here are unjustified then please first have a read of Sub Roman Britain and History of Anglo Saxon England and some of the academic works recommended there before reverting what I have done
