 And of course, you know, if you go around Cairo today, uh, you have to look hard, but you can find it. There are still, there's a Jewish quarter and there's still a synagogue. Yes, absolutely. So actually the material that I work on that I mentioned, which is this huge collection of documents, um, comes from a synagogue that is still standing the Ben Ezra synagogue in old Cairo. Um, and it was standing continually in one form or another since the 10th century and possibly even earlier.
