The President of the Carpentras synagogue, Mr. Meyer Benzecrit, graciously invited me to tour a section of the 14th century synagogue not yet open for public view. Excavations have revealed some……

Join me for three rather idiosyncratic, surprising lectures on the history of the Talmud and its transmission in the modern era. Three Wednesdays beginning November 13 at the Young Israel of Lawrence-Cedarhurst. Free and open to the community, no hard questions please.

Today was an absolutely fascinating day of discovery of Jewish history, exploring the 14th century synagogue in Carpentras, France: the second-oldest currently functioning synagogue in Europe. There are so many amazing things to view, so I’ve decided to break it up into several small videos, starting with this one, which looks at the entrance to……
