6. Jacob ben Sheshet of Gerona (flour. 1243). He wrote a Kabbalistic Treatise in rhymed prose, entitled ‏שער השמים‎ the Gate of Heaven, after Gen. xxviii, 17. It was first published by Gabriel Warshawer in his collection of eight Kabbalistic Essays, called ‏ספר לקוטימ בקבלה‎. Warsaw, 1798. It forms the third Essay in this collection, and is erroneously entitled ‏לקוטי שם טוב‎ the Collection of Shem Tob. It has now been published under its proper title, from a codex by Mordecai Mortera, in the Hebrew Essays and Reviews, entitled Ozar Nechmad (‏אוצר נחמד‎) vol. iii, p. 153, &c. Vienna, 1860. The characteristic feature of this school, which is the creative school, is that it for the first time established and developed the doctrine of the En Soph (‏אין סוף‎), the Sephiroth (‏ספירות‎) or Emanations, metempsychosis (‏סוד העבור‎) with the doctrine of retribution (‏סוד הגמול‎) belonging thereto, and a peculiar christology, whilst the Kabbalistic mode of exegesis is still subordinate in it. II.—THE SCHOOL OF SEGOVIA, so called because it was founded by Jacob of Segovia, and its disciples were either natives of this place or lived in it. The chief representatives of this school are— 1, Isaac, and 2, Jacob, junior, the two sons of Jacob Segovia, and 3, Moses b. Simon of Burgos, who are only known by sundry fragments preserved in Kabbalistic writings. 4. Todras b. Joseph Ha-Levi Abulafia, born 1234, died circa 1305. This celebrated Kabbalist occupied a distinguished position as physician and financier in the court of Sancho IV, King of Castile, and was a great favourite of Queen Maria de Moline; he formed one of the cortége when this royal pair met Philip IV, the Fair, King of France in Bayonne (1290), and his advocacy of this theosophy secured for the doctrines of the Kabbalah a kindly reception. His works on the Kabbalah are—(a) An Exposition of the Talmudic Hagadoth, entitled ‏אוצר הכבוד‎, (b) A Commentary on Ps. xix, and (c) A Commentary on the Pentateuch, in which he propounds the tenets of the Kabbalah. These works, however, have not as yet been printed. [86] 5. Shem Tob b. Abraham Ibn Gaon, born 1283, died circa 1332, who wrote many Kabbalistic works. 6. Isaac of Akko (flour. 1290) author of the Kabbalistic Commentary on the Pentateuch, entitled ‏מאירת עינים‎ not yet printed, with the exception of an extract published by Jellinek. [87] The characteristic of this school is that it is devoted to exegesis, and its disciples endeavoured to interpret the Bible and the Hagada in accordance with the doctrines of the Kabbalah.
