Who'd a thunk it?
Very often we assume that certain material goods were not available in past times, simply because nothing has survived to suggest or prove existence. This is especially true at pre-historic archaeological sites as very few organic artifacts ("organics" as we call them in the trade) survive centuries in the soil. But, something has come to light from the floor boards of an Austrian castle that has turned medieval fashion experts on their collective ears! UNDERWEAR!
Even ladies of wealth and station were thought to have their nether regions well ventilated, just because no real examples of underwear from this era were thought to have survived, until now. See the link below:
