A co-worker of mine in the Scandinavian languages department noticed
your runes. She pointed out to me how they show the Old Norse vowels
in an extraordinary fashion. I agree. I have taught both Modern
Swedish and Old Norse for over 20 years in a variety of academic
environments. Your diagrams illustrate the character of the Old
Norse vowels and show how they are related in a away that is both
clear and correct from an historical perspective. I believe this
could be of great value to students and teachers of both Old Norse
and modern Scandinavian languages, and I encourage you to publish
educational materials on this topic.
