Most of the translations of the Ante and Post Nicene Fathers which I have are from a 38 volume translation done in Edinborough in the 19th century, by Anglicans I presume. These are the "definitive translation" thusfar, but I understand from one of the Latins on FR that a new translation is being done, though it isn't complete.
Interesting! Again, thank you! (38 volumes.... why, that just speaks... volumes!)
