The hypotheses concerning the Arabic content in the Divina Commedia by Dante Alighieri do not examine the social and the cultural conditions of Florence in Middleages which motivated writers and poets to make use of transculturation, cultural transfer, and the crossing of cultures from one land to another in a free and boundless movement. In my opinion, it is necessary to adopt sociological element that can interpret the influences that a certain literature underwent, without investigating or denying the originality of the work in question, especially when it comes to the great works of the history of world literature. This article combines two divergent concepts, but they serve as tools to explain the famous concept of influence in traditional comparative literature and open a new window that contrasts the nationalist tendencies of this type of study. On the one hand, there is the so-called cultural mobility, in which we use a specific definition that was used in social studies, and it sets conditions for the transmission of thought and ideology, through language and literature, from one part of the world to another, and from generation to generation. On the other hand, there is the so-called pure literature with different definitions, but they share a common notion, a purifyed literary essences, which is the concept we used to liberate transmissible literary notions from their descriptive and contextual constraints.
