Maureen has left a note to tell me of another site where bits of the fathers are being translated. It’s here. The author is John Litteral, who appears to be translating extracts from ancient biblical commentaries. If so, this is very welcome! I’ve not managed to find my way around the site yet to be sure.
There is also a collection of links to the fathers. Among the links is one to a site by Gary Anderson and a translation of portions of Ambrose’s De paradiso, here. As far as I knew this was untranslated.
