the thousand and one nights – or, as i prefer to call them in the following for purely practical reasons: the arabian nights – as we perceive them three hundred years after antoine galland’s epochal french adaptation bear a distinct arabic imprint. meanwhile, the commonly accepted model for their textual history acknowledges various stages in the conceptualization and effective formation of both the collection’s characteristic frame story and the embedded repertoire. the vast majority of tales in the preserved manuscripts of the nights has been integrated into the collection during two periods of arabic influence, the so-called baghdad and cairo periods (gerhardt 1963: 115–374). these “arabic” stages are preceded by an iranian version, probably dating to pre-islamic times, which in its turn profits from both structural devices and narrative contents originating from indian tradition. considering the eminent position that iran and iranian culture hold in the early stages of the textual history of the arabian nights, surprisingly few details are known concerning the collection’s relation to and its actual position within the iranian cultural context. in the following, i will discuss links between the arabian nights and iranian culture on several levels. in surveying these links, i will treat five major areas: (1) the iranian prototype of the nights; (2) tales of alleged persian origin; (3) persian characters within the tales; (4)persian translations of the arabian nights; and (5) the position of the arabian nights in modern iran

edwards uses the phrase "o who can express what the state of a soul in such circumstances is! " in order to illustrate that this type of suffering is unimaginable. the word "express" denoted that the state of a suffering soul is required to be described by any person, but it would not happen because no one can imagine how this suffering is felt.  

-show what might happen if the reader disobeys edwards is not correct because this is described trhough the text, not by the phrase used.

-describe what endless suffering looks and feels like is not correct because this description might be the porpuse of the excerpt provided, not the porpuse of using the phrase during the writting.

-prove that few people have survived limitless suffering is not correct because it is implied that the soul of a person is already suffering and doesn't have any way to escape.
