Sefer HaBahir - c.200 - c.1200; The "Book of Brightness" is an anonymous mystical work attributed to first-century rabbinic sage Nehunya ben HaKanah. Modern scholars date the esoteric, theosophical work to the beginning of the 13th century, amongst an unidentified circle of medieval Ashkenazic esotericists, and posit that its emergence marks the literary debut of Kabbalah. Medieval kabbalists write that the Bahir did not come down to them as a unified book but rather in pieces found in scattered scrolls and booklets.
