[MR] Looking for historical references on medieval oilcloth

[M. Minx]

I'm trying to research medieval flooring, particularly painted oilcloth or
floorcloth.  I've seen vague references to oilcloth being seen in the 14th
century, but no hard references.  I have also looked in the Floregium, and
only found one thread, with *no* references.  Google has yielded little.
One reference to rushes being replaced with carpets and/or mats (of no
reference) after the Black Death in the late 1300's.

So, I'm turning to the brain collective here.  Any help would be deeply
appreciated!

In service,
