Not Tolkien, Buddha, or Ascham.
Tosh, did Edward VI really translate psalms into English? I never knew that!
Didn't he only live to be about 16 or so?
Edward VI did not probably do it at all himself, but in his name. He was very much wanting to make England Protestant again after his sister's reign, and was almost zealous in his support of the new "true" Protestant faith(s). Of course, he was also exploited to the extreme by those in his court. Who knows what was truly done by his will or by those stating it was his will.
To answer the original question, I am guessing that this guy lived long ago, since he himself needs to be translated into modern English while trying to put Psalms into English. That makes me think far older than anything Tudor. Yet, Jude hints that while we would normally associate this with a cleric or church official, this is not the case.
Stabbing at air here, so I will come up with Chaucer, am I even close?
