Heterodoxy (or really, orthodoxy) wasn't really a thing in 79ad, and you're not likely to find much of it in the private library of a wealthy Roman's vacation home. The only forbidden work you're going to see from that era is stuff critical of the emperor.

I mean heterodox as seen by medieval monks, so deeply unchristian things, for example.

It's hard to imagine something more heterodox than Ovid, and that survived. Medieval readers didn't seem to mind that sort of thing in Greco Roman writing, it was part of their heritage, no one was seriously worshipping those gods so it wasn't seen as a threat. The people in the past behaving in a way that was seen as immoral wasn't a problem.
