The Douay Rheims is a translation of the vulgate. The vulgate is the ONLY canonized Catholic Bible - it is THE perfect Bible containing no errors. If you seek translations before that, you are not reading the Bible as canonized by the Church. Therefore, the DR is not a translation of a translation - it is a translation of the only perfect translation.
Correction: The Vulgate has no theological
errors. It has plenty of linguistics errors however. This includes an amusing rendering of Psalm 45 where the Psalmist - in Latin - "burps" his praises to God. The Vulgate has gone through a number of revisions, the most recent being in 1986.
Reading the best translations, as the saying goes, is like playing Bach on a tin can. The Vulgate is no different.
If one wishes to hear not only the message of the Bible, which a good translation can relate, but the way
in which God spoke to mankind, a knowledge of the original languages is necessary. No translation can convey the manner, the grammar and syntax, with which the Holy Spirit spoke to mankind.
The original versions do not exist. The Vulgate is the ONLY copy of the Bible guaranteed by the Church to be completely free of doctrinal error. You can not study the original texts if they don't exist. Fortunately for us St Jerome did and his translation - canonised by the Church is still extant.
Interestingly, you say: "which a good translation can relate" after deriding the canonized vulgate - what translation exactly do you think is better than the only canonized version of the Bible in the Catholic Church? Please name some manuscripts or editions. Oh - and if one wishes to hear the message of the Bible they should listen to the traditional teachings of the Catholic Church - not an "improved" Bible from the 1980s, 20 years after "the smoke of satan" ... "entered the sanctuary".
Just to reaffirm what I am saying (which I wouldn't do if I were debating a Catholic) - the Latin Vulgate of St Jerome is CANONIZED - ie, infallibly declared to be free of error - by the Catholic Church and no other copy of the Bible is or ever has been. You can argue grammar all you like- but the Bible of St Jerome is perfect in that it is the ONLY copy of the Bible that exists in the way that God intends it to be (remember the whole, "bind on earth" thing?)
