I stared at the article and it sounds like a very "technical" archeological description of some old hand copied and illustrated book.
I looked into it because I expected rather something about maybe a romantic sufi in contrast to a 'plain' sufi or something similarly related to the title --- and accessible to a lay person.
confused I dare to kindly ask: what's so special about it that you share it here on HN?
They misspelled the word "stole".
