A correspondent has drawn my attention to a couple of sites with Romanian translations of the Fathers on them:
As for [patristic literature in] Rumanian (i.e. translations from Fathers) I might estimate that there are some 50-60 volumes of PG authors and 5-10 PL authors translated, from 1700 up to our own days.
There are also internet sites with works of the three Holy Hierarchs:
However, I don’t know a page linking all these sites.
You may be asking why we care. Well, I tried the last site. I don’t know any Romanian, so I used Google translate. I found that it really worked quite well. In particular I found this translation of Chrysostom against Jews and Gentiles that Christ is God here. At points I had to rub my eyes and check that it was not in English to start with.
So I think there are treasures to be found there.
