This manuscript contains one of the four autographs of Elijah ben
Solomon Zalman, known as the Vilna Gaon ("exceptional Talmud
Scholar") (1720–1797). He was revered during his lifetime already
and is considered the most important scholar among Lithuanian
Ashkenazi Jews; his teaching influences Judaism up to today. This
autograph comments on a passage of the Zohar, the classic work of
Jewish mysticism. The comments from this manuscript were printed in
the 19th century, carefully reproducing even the marginal notes and
corrections in this manuscript.
