  Shem-Tov ibn Falaquera was a prolific author. Most of his philosophic works and translations are extant and have been edited at least once. In fact, the only extant work of Falaquera’s that has not been edited and printed is his encyclopedia of science and philosophy, De‘ot ha-Filosofim (The Opinions of the Philosophers), which is extant in two manuscripts, and Ilya Levkovich is currently engaged in editing parts of it. Falaquera mentions in his writings books of his that are no longer extant: Megillat ha-Zikkaron (Scroll of Remembrance), in which “I spoke of our trials of the past, for at present, hordes of afflictions come upon us daily” (Sefer ha-Mevaqqesh, 12; trans., 7]); Sefer ha-Derash, apparently a philosophic commentary on the Midrashim (Moreh ha-Moreh, II, 26, 287); a Commentary on the Torah and a Commentary on other books of the Bible (Moreh ha-Moreh, introduction, 116), and a Commentary on Proverbs (Moreh ha-Moreh, addendum chap. 1, 337; cf. Reshit Hokhmah, 10, and Sefer ha-Ma‘alot, 39). He also expresses his intention to write a Commentary on Ecclesiastes (Iggeret ha-Vikkuah, 71; trans., 37). Passages from Falaquera’s lost Bible commentaries and perhaps also from his Sefer ha-Derash have been preserved in two writings of Samuel ibn Sarsa. These have been edited and translated in Jospe, Torah and Sophia, 468–484 (from Ibn Sarsa’s Meqor Hayyim) and in Jospe and Schwartz, “Falaquera’s Lost Bible Commentary,” 186–200 (from Ibn Sarsa’s Mikhlol Yofi).
