Who really wrote Unetaneh Tokef?
I like to think I'm pretty savvy about the origins of various minhagim, and I usually look at the legends behind the various customs with a skeptical eye. But I only learned today that the Rosh Hashana prayer "Unetaneh Tokef" was found in the Cairo Geniza, in a manuscript dating to the 8th century. That is far earlier than the traditional belief in the story of R Amnon of Mainz in the 10th or 11th century, who wrote it as he lay dying because of his refusal to convert to Christianity. I had already viewed the details of this story as suspect, because it smacked of being too perfect in its emotional impact. But until today, I still assumed that the authorship, and its time period, were relatively accurate. It turns out that the issues with the authorship are well-known, and have been for half a century. The Geniza manuscript was known to scholars as early as the 1950's. And that is not not the only issue with the traditional story. See this Schechter Institute
