I spent 3 yrs in Elazig ( Kharpert / Mamuret-ul-Aziz ) and the last Assyrian priest ( Abouna, they call ) there was my patient. He used to copy ancient prayer books from the monastery of Deir-ul Zeferan in Mardin. Their alphabet is the oldest in Mesoptamia after Hammurabi's cuneiform scripts. He prepared ink from walnut peel extract for calligraphy etc.
and jotted down holy scripts beautifully.
Although there was only a handful of Suryanis left there , he expected them all to attend
" Namaz " every week. I learned later that " Namaz " was originally an Assyrian word.
