Old English had been a central mark of the Anglo-Saxon cultural identity. With the passing of time, however, and particularly following the Norman conquest of England, this language changed significantly, and although some people (for example the scribe known as the Tremulous Hand of Worcester) could still read Old English into the thirteenth century, it fell out of use and the texts became useless. The Exeter Book, for example, seems to have been used to press gold leaf and at one point had a pot of fish-based glue sitting on top of it. For Michael Drout this symbolises the end of the Anglo-Saxons.
