Sample Topics - General:
Exotic Kosher Animals –
From peacocks to locusts, guinea hens to yak. Realize how mesorah and our ancient traditions of kashrut are being lost. Understand how those ancient traditions have been recorded from places like Yemen,Tunisia and Djerba.This is a talk about halachic detective work and halachic forensics and an attempt to save it.
The Great Matzah Wars–
The confluence of one of our most ancient and simple customs and the industrial revolution made the need for machine matzot to be a reality. The halachic literature of the time is a fascinating example of modernity meeting tradition. The debates that ensued were among the most acrimonious halachic discussions in the last 2 centuries.
The Search For The Holy Snail–
Nobody has worn tekhelet for close to 1300 years. 18 years ago together with 2 friends we went scuba diving to try and rediscover the snail and process for dying tzitzit for tekhelet. Join me on that journey. It will be a multimedia presentation on the history,halacha,archeology , biology and the chemistry of color and tekhelet. I will do a demonstration on ancient dyeing techniques.
Exotic Jewish Communities-
Take a halachic tour of Jewish communities from Asmara, Eritrea to Djerba, Tunisa, from Djibouti to Bahrain. Spend shabbat on the island of Byeukeda in Turkey where the only mode of transportation is still horse and buggy or trek to the Atlas mountains in Morocco to see the ancient etrog orchards. Yom Kippur in Adis Abbaba or Pesach baking matzot in the mountains of Portugal. That is only a small part of the halachic mosaic and world minhangim of the exotic Jewish communities.
