all this, there are issues on which Dante diverges from the scholastic doctrine, such as in his unbridled praise for poetry. Islamic Dante lived in a Europe of substantial literary and philosophical contact with the Muslim world, encouraged by such factors as Averroism ("Averrois, che'l gran comento feo" Commedia, Inferno, IV, 144, meaning "Averrois, who wrote the great comment") and the patronage of Alfonso X of Castile. Of the twelve wise men Dante meets in Canto X of the Paradiso, Thomas Aquinas and, even more so, Siger of Brabant were strongly influenced by Arabic commentators on Aristotle. Medieval Christian mysticism also shared the Neoplatonic influence of Sufis such as Ibn Arabi. Philosopher Frederick Copleston argued in 1950 that Dante's respectful treatment of Averroes, Avicenna, and Siger of Brabant indicates his acknowledgement of a "considerable debt" to Islamic philosophy. In 1919, Miguel Asín Palacios, a Spanish scholar and a Catholic priest, published La Escatología musulmana en la Divina Comedia (Islamic Eschatology in the Divine Comedy), an account of parallels between early Islamic philosophy and the Divine Comedy. Palacios argued that Dante derived many features of and episodes about the hereafter from the spiritual writings of Ibn Arabi and from the Isra and Mi'raj or night journey of Muhammad to heaven. The latter is described in the ahadith and the Kitab al Miraj (translated into Latin in 1264 or shortly before as Liber scalae Machometi, "The Book of Muhammad's Ladder"), and has significant similarities to the Paradiso, such as a sevenfold division of Paradise, although this is not unique to the Kitab al Miraj or Islamic cosmology. Many scholars have not been satisfied that Dante was influenced by the Kitab al Miraj. The 20th century Orientalist Francesco Gabrieli expressed skepticism regarding the claimed similarities, and the lack of evidence of a vehicle through which it could have been transmitted to Dante. The Italian philologist Maria Corti pointed out that, during his stay at the court of Alfonso X, Dante's mentor Brunetto Latini met Bonaventura de Siena, a Tuscan who had translated the Kitab al Miraj from Arabic into Latin. Corti speculates that Brunetto may have provided a copy of that work to Dante. René Guénon, a Sufi convert and scholar of Ibn Arabi, rejected in The Esoterism of Dante the theory of his influence (direct or indirect) on Dante. Palacios' theory that Dante was influenced by Ibn Arabi was satirized by the
