I've been reading about the practice of trepanation in the hills of Algeria and I came across this cool tidbit. Apparently, some practitioners considered the cranial sutures to be the calligraphy of Allah who uses writes destiny of each person on their skulls. Cranial sutures do kind of look like a loose script of some kind. And, Islamic calligraphy is some of the most amazing art in the world so I could see the connection.
(Calligraphic fire via Islamic Arabic Caligraphy and the book on native Algerian Medicine is Hilton-Simpson's Arab Medicine and Surgery. A Study of the Healing Art in Algeria)
