::::::: It's in Romanian, so you wouldn't understand much. The legend says otherwise. Nothing wrong with Zalatarki. However "ib" by Pachymenes is not a real reference. Also, I was not able to find any inforamtion about the book by Andreev. A 1996 book surely has a ISBN, but I couldn't find one. I'll try to add more about to subject from Western sources, only if you get rid of the irrelevant information.
