infundibulum

I started a category on Wikipedia: Category:Earliest known manuscripts by language. I’m not terribly happy with the phrasing of that, but I couldn’t come up with anything better. Anyway, it seems to have struck a chord as there have been daily additions since the addition.

As you might expect, there are some arguable cases, but IMHO, the discussion about which particular documents belong in the category and which are on the periphery is the whole point.
