[LM_NET] Interior Door? When was the first!?

[Elizabeth Savage Kamke <EKSK476@AOL.COM>]

Here's a question that has me stumped.  What is the earliest example (in Western 
architecture) of an interior door, and what was the purpose of the interior door?

I've checked Famous First Facts, but no luck.  Does anyone have any idea where to 
find this information?  My fingers are crossed.
