The book known as Yosifun, cherished in traditional Jewish circles, and the books of Josephus, preserved in Greek and Latin by non-Jewish hands, spark challenging questions about authorship, reliability, and reconstructing the Jewish past. This class explores how rabbis throughout the ages evaluated these works, their role on the Jewish bookshelf, and how to navigate the apparent discrepancies between their accounts and the teachings of chazal. Josephus

The Books of Maccabees tell the dramatic story of the Chanukah revolt and the heroism of the Jewish fighters. But who wrote these books, and why were they left off the Jewish bookshelf? We’ll discuss the history of these texts, explore their reception among Jews throughout the ages, and probe the role they played—or didn’t play—in shaping Jewish memory of the Chanukah story.

When a shipwreck in the 1500s left families wondering about the fate of their loved ones, rabbinic authorities debated whether the wives of the missing passengers could remarry. This centuries-old question resurfaced in 1912 with the famous sinking of the Titanic, reigniting the discussion of applying Halachah in tragic circumstances.

We kick things off with seven fascinating stories from the teshuvos of medieval Spain, where we discover shul seats being treated like real estate: bought, sold, inherited, mortgaged—and sometimes the center of heated disputes. Then, we shift our focus to Ashkenaz, where this phenomenon is noticeably absent, suggesting a very different set of attitudes and conventions about shul seats. Finally, we dive into how the poskim tackled some of these disputes, applying Halachah to their contemporary realities. Benches, Bargains, and Bickering: Shul Seating in the Middle Ages
