The dream of the conversion in Ramon Llull is related with the own author’s vital vicissitudes. Therefore, the Islamic influence in the lulian system is obvious, besides the knowledge of Arab sources on the part of the author. On the other hand, Mohammed’s vision and the Islam that Ramon Llull presents is intimately related with its apologetic plans, inserting it in the Christian tradition of rebuttal, being in to traditional way a topic like the Antichrist.
