English of 500 years ago

That's from the ([Dutch] University of Groningen) The Skeltonproject

They obviously do a good job of it. Preserving old languages for posterity, historical and cultural reasons will be a profitable business in coming years; I don't picture more than about ten or twelve of the languages spoken today still being here 25 years from now.

My question would be where did they speak English that way? I'll bet it sounded a good deal different in Yorkshire, for example, just as is the case today.

Skelton was known for "cultivating English as a language suitable for poetic composition". So it doesn't seem to be a 'regional' English but perhaps something 'Queens English'.

It's done by students, part of "a self-organised module within the Research Master Classical, Medieval, and Renaissance Studies". [MA in Classics & Ancient Civilizations (research). or MA in History (research), or MA in Literary Studies (research)]
