In his surroundings, man deals with the names of people, places, animals, plants, things, … for most of which, he has no idea as to the origin of their nomination. One of the questions, occupying the curious mind of man, is to find the actual relationship between the signifier and the signified.Nomenclature is widely used in literature especially in Gnostic texts. Due to their individual viewpoints, poets and Gnostics look around themselves differently which leads to a unique sense of creativity in the process of mystical nomination.
