Making a Maskil Mainstream: Adapting Haskalah Scholarship for a 19th-Century Rabbinic Audience

Abstract The Passover Cup of Elijah is often explained as an expression of rabbinic uncertainty regarding a fifth cup mandated by some opinions in the Babylonian Talmud. The explanation is based upon other talmudic passages which mention halakhic uncertainties that will be resolved by Elijah when he eventually comes to herald the long anticipated redemption. The explanation is commonly attributed to the Gaon of Vilna; however, no historically reliable source supports this attribution. This explanation was first published by the great maskil, Isaac Ber Levinsohn, and was attributed to the Gaon of Vilna by Eliezer Zweifel. An alternate shift of attribution was to R. Ephraim Zalman Margolioth. Attribution to a great rabbinic authority helped the explanation gain circulation and approval among the general rabbinic audience to the present day.
