Greg72:
Very much, thanks (those are a couple of great sites - immediately bookmarked)
So, now it looks like the Latin Vulgate, erroneously translated the Hebrew “r’em” as “rhinoceros”, which in at least one case (“monoceros”) became “unicorn” in the Douay-Rheims. The King James Version then made all occurances “unicorns” and most (if not all) other versions moved to correct the original error, making them “wild oxen”.
I have been curious about this for quite some time - unicorns just didn’t seem to fit into the Old Testament very well, and I wondered where the KJV got them from. I’m now wondering why the KJV hasn’t been revised.
It has - but it’s all rather complicated 
The AV of 1611 (KJV in the USA) was revised in
1881 - NT
1885 - OT
1895 - Apocrypha
This revision affected only the UK
In 1901, the USA scholars who had been in touch with the British Revisers published a US equivalent of the RV, called the American Standard Version. Quite a few conservative Protestants in the USA seem to like the ASV - at least if they’re Presbyterians.
in 1946, in the USA, an NT revision of the ASV was published, followed in 1952 and 1957 by the OT and Apocrypha - this is the Revised Standard Version, or RSV
The New American Standard Bible is a revision of the ASV as well, in a more conservative direction than the RSV - the NT was published in 1963, and the OT in 1971. As a Protestant version, it keeps to the 66-book canon
Back in 1946 again, it was decided in the UK to produce a completely fresh translation of the Bible, which would not be a version in the tradition of the AV. This is the New English Bible (NT 1961; OT & Apocrypha 1970), and is of Protestant origin; it should not be confused with the NAB, which is Catholic, from the USA, and began as a revision of the 1941 Confraternity Version, itself a revision of the USA edition of the Challoner Bible, itself a revision, with more than a hint from the AV, of the Douay Reims (and that is a simplified account
)
If your head isn’t spinning, read on…
in 1965-66, there were British and US editions of the RSV for Catholics
in 1973, the Common Bible, an edition of the RSV for Protestants, Catholics, & Orthodox, was published.
At some stage - in the 1980s ? - there was a light modernisation of the AV-KJV, which is called the New King James Version. I think it’s from the USA. It tidies out the verses which rest on weak or textual evidence, but is basically a titivated form of the KJV.
And that’s basically it - a skeleton account of the relation of the modern versions to the AV.
