I am currently researching Philo of Alexandria, also known as Philon (פילון) or Yedidyah HaKohen of Alexandria.
There is a book that was prepared in manuscript by Rabbi Shmuel (Samuel) Belkin, z”l, the past Rosh Yeshiva of Yeshiva University called The Midrash of Philo (מדרשי פילון) which was intended to be six volumes. In Rabbi Belkin’s introduction to volume one, he goes into detail about the content of each volume.
Rabbi Belkin passed away before the book was published but Rav Avraham Yosef Hirschprung and Rabbi Elazar Hurvitz took it upon themselves to actually bring the manuscript to publication.
Volume one was successfully published by Yeshiva University in 1989 (5749). But the remaining five volumes never saw the light of day.
Does anyone know where this manuscript went or how to contact Rabbis Hirschprung and Hurvitz?
I would like to assist in finally getting the remaining five volumes published. It is long overdue.
