Sefer Eliya Rabba Manuscript by the Vilna Ga'on on Mishnayot Taharot
Sefer Eliya Rabba Manuscript, commentary on Mishnayot Taharot, by the Vilna Ga'on. Manuscript begins in middle of chapter 8 of Keilim Tractate until end of Seder Taharot. Handwritten copy of composition from the 1740's, which possibly precedes first printing of the book in the year 1802. Last page contains colophon:"Blessed is G-D who has assisted me in completing this letter, may He merit that I study and understand it, Yitzchak Eizik son of Rabbi Moshe of Lisa".
Sefer Eliya Rabba was written by Rabbi Meir of Vilna, who studied with the Vilna Ga'on, and copied his commentaries"It was spoken by him and I put it down in ink" (his wording in the preface). Sons of the Vilna Ga'on undermined this composition claiming that it was copied with many errors, nevertheless, this composition was printed in many editions on the Mishnayot. See attached material.
