Husband says he would be writing in neither, he thinks. It would probably be Greek or Aramaic. And it depends who he's writing to - ie what he thinks they can understand. He would probably be able to write in both.
Greek equals lang of En. Roman Empire (Greek equals normal lang of Romans in the East)
Aramaic equals lang of Assyrian Empire & Persia. (Jews adopted this lang. after the exile in Babylon which was 500 BC-ish.)
At the time the hermit is writing, Hebrew would be the equivalent of Shakespearian English to us - so v. old-fashioned. The Dead Sea Scrolls are mostly Hebrew, some Aramaic, but they are 200BC to 60AD, so Hebrew is dying out at the end of when they were written.
NB Latin is lang of Wn Roman Empire, but if hermit is Jewish he probably wouldn't be Western, as most Jews were in the East.
Hope that helps - yell if you need more as K is a mine of theological information. Worryingly, he could tell me most of this without looking up in his theological tomes!! We need to get out more ...
