Any rug experts out there?

Hail, Gentle Readers! Amongst you you have enough erudition to run a small Eastern European country. So I come to you with this: We have 2 matching SILK (or maybe silk blend) Persian rugs, 5 ft x 7 ft, ca. 550 KPI, that we want to sell on CraigsList (or eBay, I suppose, though shipping them would be nightmarish - or is it possible to state that the person who buys them must come pick them up?). Delia bought them ca. 1987 (pre-Ellen!) from the renowned Gregorian Rugs. She can't find the receipt now, but remembers lots of zeros. It would be nice to know roughly how many - and also, just what it is we've got here - I don't even know how to describe it . . . It's "modern," I know that, i.e. not an antique, which makes them less valuable, but they are silk, and very fine workmanship. Also pretty. I have taken many photos.
( Here is one. )

howbout medieval uni's?

Thank you for the wise rug advice. And now for something completely different - Nicholas Laccetti sent me this query on FaceBook (which is, to my mind, I'm sorry, a completely useless appendage when it comes to joint interaction and we should all just switch to LJ unless we care passionately about acquiring pixellated beers):

Lately I have been looking around for books set in or about medieval universities (fiction or nonfiction). Since you co-wrote the wonderful Fall of the Kings, I figured you might have some recommendations.

Flattery will get you everywhere - including access to my Brain Trust.

Well, friends?

Me, in non-fiction I would recommend anything about Peter Abelard - it was "his" Paris university that we had in the back of our brains when we started working on Kings. We also read Will & Ariel Durant . . . I'll have to ask deliasherman what else, when she gets up from her post-novel-nap.
