Nowell's maps offer us a chance to see, quite literally, his idea of England and his associated desires for his Anglo-Saxon research. Even though some of his maps do not directly participate in his Anglo-Saxon studies, they were probably related, as F.J. Levy argues:

Viewing Nowell's maps as merely background for his place-name research, however, misses their own nationalistic agenda and claims, claims crucial to his very idea of what England was, what it wasn't, and what he wanted his medieval studies to accomplish. Although considering his maps may seem a departure from studying the Abcedarium and his other Old English materials, such an examination reveals important, but overlooked, evidence of Nowell's broader cultural context and aims. The maps not only show us how he saw England and Ireland, but also how he viewed the past and the present, and how those categories, seemingly separate, became reinforcing. This has repercussions for all aspects of his Anglo-Saxon research beyond just chorography, as it gives us a framework for his linguistic and legal studies as well.
