Although this philosophical influence is generally acknowledged, 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. Even so, while dismissing the probability of some influences posited in Palacios' work, Gabrieli conceded that it was "at least possible, if not probable, that Dante may have known the "Liber Scalae" and have taken from it certain images and concepts of Muslim eschatology". Shortly before her death, 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 Turkish academic Orhan Pamuk in his novel "The Black Book".
