==== In the Period of the Tannaim ====
There were several [[Tannaim]] known for engaging in [[Toras HaSod]]. Among them were Rabbi Nechunya ben Hakanah, to whom several works in Toras HaSod are attributed: Sefer Hakanah, Sefer HaBahir, Sefer HaPliah, and Sefer HaTemunah; as well as [[Rabbi Yishmael]] and [[Rabbi Akiva]], to whom Pirkei Heichalos and others are attributed. The central figure among the Tannaim who engaged in Toras HaSod was [[Rabbi Shimon bar Yochai]], who together with his son Rabbi Elazar and other Tannaim from his group composed the Zohar. This book was hidden for over a thousand years (though some Geonim and Rishonim may have known it), and was revealed in the first century of the sixth millennium by the Kabbalist Rabbi Moshe de Leon. Since its publication, the book became a foundational text of Kabbalah, and many Kabbalistic writings are based on it.
