König, Götz. 2019. The Idea of an Apocalyptic Fire According to the Old and Middle Iranian Sources. In Jochen Althoff, Dominik Berrens & Tanja Pommerening (eds.), Finding, Inheriting or Borrowing?

A reasonable method through which to approach the reconstruction of religious phenomena in Iran would be to view the phenomena involved from this double perspective involving vertical and horizontal relationships. Defining the perennial and the changing elements, kernels and agglomerations, etc., would surely be helpful in this respect. So too would the drawing up of chronologies related to the history of religious ideas in Iran. The idea of an apocalypse – and this idea is, as we shall see, essentially the idea of the end of the world in fire – is a good example upon which to base a historical analysis located in the aforementioned double bipolar field: Zoroastrianism and Manichaeism; Avesta and late antique religious text.
