Hello! I am Rosina Catalan from Indianapolis, IN. I am a high school Latin teacher. I use very little digital sources but lately I am into Museum databases. I visited Cairo last month and found the use of the term Anno Hejirae (A.H.) which is a form of dating (like A.D.). I have taught this to my students in the past but out of theory - but I got to see it in use at the Islamic Art Museum in Cairo. To me, Islamic art is just beautiful.
