With Rabbanit Dr. Naomi Cohen in the Women’s Talmud class, over 30 years ago. It was a “known” class and it was accepted, because of who taught. Since then I have also studied with Avigail Gross-Gelman and Dr. Gabriel Hazut for about a year). Years ago, in a shiur in my shul, I did know about Persians doing 3 things with their clothes on. They opened the shiur to woman after that!
