Dionysius Exiguus and AD/BC

Isn’t the web wonderful?  I’ve long wondered why there was no English translation of the work in which Dionysius Exiguus first stated the date using AD and BC.  Indeed it should have been translated, surely, as part of the millennium celebrations, I thought.  But quite by chance I find that a certain Michael Deckers has translated a large chunk of it, which appears on a Russian site here.  A link to the full Latin text is also on that page.  I have written to Dr Deckers to ask permission to include it in the Additional Fathers, and perhaps I will translate some more of the work.
