Catalan compiled, about 1280, an encyclopedia entitled "Sha'ar ha-Shamayim" (Door of Heaven), which contains many quotations and even whole treatises from previous translations of works written in Arabic. Following Shem-Tov ibn Falaquera, he divided his work into three parts, dealing respectively with: (1) physics, including natural phenomena, metals, plants, animals, man, and a chapter on dreams; (2) astronomy, taken chiefly from Al-Fargani and the "Almagest"; and (3) theology or metaphysics, which part, as Catalan expressly says, contains nothing new, but is a copy of Maimonides' "Book of the Soul". The Greek authors cited are Alexander of Aphrodisias, Aristotle, Empedocles, Galen, Hippocrates, Homer, Plato, Ptolemy, Pythagoras, Themistius, and Theophrastus; the Arabic: Ali ibn Abbas al-Magusi, Ali ibn Ridwan, Averroes, Avicenna, Costa ibn Lucca, Al-Farabi, Al-Fergani, Hunayn ibn Ishaq, Isaac Israeli, Ibn Tufail, and Ibn Zuhr. The work was published in Venice in 1547 and Rödelheim in 1801.
