Uuuaaahhh...I'm confused...The above are wrong, I hate to say. R.R. stands for 'Ronald Reuel'. His full name was Cato Ronald Reuel Tolkien.
Hi - see here and here.Actually, I am a bit confused about something. I haven't found, anywhere, the De agri cultura referred to as De re rustica. I have noticed, however, that Cato's treatise on agriculture has often, in the past, been bundled together into the same volume (at least by English language publishers) with Varro's (Marcus Terentius, in particular) Rerum rusticarum de agri cultura. Just wanted to check against conflation of these, as what I was looking for was not in part 10 of De agri cultura, but rather, I found it in paragraph 10 of Rerum rusticarum de agri cultura.
