Noam Sienna is a sofer, author,[1] and Jewish educator[2] in Minneapolis.
[2] The topic of Sienna's undergraduate thesis was the use of henna in Jewish traditions.
Sienna studied in Israel and interviewed Jewish immigrants from other countries including Iraq and Yemen, gathering information about traditions that had become obscure.
He found that henna was traditionally used by Jews in the Middle East and Africa to commemorate life-cycle events such as birth or a new home.
[4] Sienna's book A Rainbow Thread: An Anthology of Queer Jewish Texts from the First Century to 1969, published in 2019,[5] comprised a collection of 120 texts from 16 languages related to rabbinic perspectives on sexuality and gender.
