See, you've fucked up. Because now you've pissed me off. These are the only references to what you're talking about.

"At the provincial Second Council of Tarragona (Conventus Tarraconensis) in 1234, the Spanish bishops, according to a decree of King James I of Aragon, declared that it was forbidden to anyone, to own a Romance language translation of books of the Old and New Testament."

"in 1229 at the Council of Toulouse, the Catholic Church actually made it illegal for anyone other than the clergy to own a copy of the Old or New Testament, otherwise, he must be executed."

None of this is Dark Ages.
