Kāhen family. The mahalleh in Golpaygan, 1941. Rabbi Shemu’il Kāhen (third person from left) was educated in Iraq. He was the head rabbi in Golpaygan. The photograph was taken in his personal library, which is only partially visible here. The books, all in Hebrew, were brought to Iran from Iraq on camel back. The men’s hand gesture — a gesture used by the Cohanim during the priestly benediction in the synagogue in front of the arc — signifies their status as Cohanim. The men on either side of Rabbi Shemu’il are his sons. The child is his grandson.
