A Scribal Error?
I’m going to show you two letters, and two names written with those characters, and give you all something to mull over.
Errors on my part here in this rendering aside, pay attention to the last letter. Arthwyr or Arthwys? How easy of a mistake to make.
R & S - ah the great Irish alphabet!
So some ancient monk, drinking a bit got slobbered and messed up is S and thats how got King Arthur? 😫
