Here is the Translation into modern English:
"The Island of Britain is 800miles long and 200wide. There are on this Island five languages: English and British and Welsh and Scottish and Pictish and Book-Latin. "
"First to live in this Island were the Britons. From Jutland came the people of Kent and Wight. From Old Saxony came the people of Essex and Sussex and Wessex. From Angeln came the people of East Anglia, Middle-Anglia and Mercia and all of Northumbria. Their war leaders were two borthers, Hengst and Horsa."
Simply fascinating to all the English, Scandinavian and Teutonic peoples alike.
