Many thanks for this very interesting article and link; it’s right up my alley! ;^)
There’s a movie, starring Charlton Heston, called “THE WARLORD”, that sort of deal with this subject, in a way; great movie, BTW and if you haven’t seen it, see if it’s on YouTube. It has a GREAT caste, is well written and acted, and is spot on accurate re costumes and even hairstyles, and historical data, but in modern day English, instead of the way early English was spoken.
Thanks, will look it up.
