Would you believe me if I told you that I actually was thinking
Cybele might be the goddess in question? ;-)
Unfortunately, the book didn't give any further information and as I'm far from being an expert on Turkish names, I figured for once I'd rather not stick my neck out and mention
Cybele.
I'm still trying to find out if the Turkish
Suzan really is derived from a Persian word for "fiery; ardent; burning". You don't happen to have any information on that name by any chance?
