Rezania, Kianoosh. 2017. The Dēnkard Against its Islamic Discourse. Der Islam 94(2).The Dēnkard is the most exhaustive Pahlavi work ever produced in Zoroastrianism. Due to the large amount of information included in it, this body of work has often been referred to within the field of Iranian Studies as a ‘Zoroastrian Encyclopedia’. This article discusses two main points. First, it holds that it was not the intention of the Dēnkard’s authors and editors to compose a Zoroastrian encyclopedia in the 9th and 10th centuries. By contrast, the independent texts which serve as the basis of this compilation deal with other religions or present a Zoroastrian apologetic. It also claims that the Dēnkard has not been perceived as an encyclopedia in later Zoroastrianism. Second, the article scrutinizes the editorial process that led to this book. It furthermore argues that the Dēnkard, in its current form, has been structured to resemble the Zoroastrian world history comprising nine millennia. This article aims, moreover, to show that the last three books of the Dēnkard aim to depict Zoroastrians as belonging to the People of the Book. The article finally argues that the Dēnkard should be considered entirely a theological apologetic within an inter-religious context, which was mainly carried by Muslim theologians.
