Kirder and the Re-organisation of Persian Mazdeism

The ascent of the Sasanian dynasty had an enormous impact on the future development of Zoroastrianism, particularly in western Iran. This assumption is based on objective evidence, which is unfortunately not always fully considered by historians in all its heavy implications. This evidence consists of ritual and theological Mazdean sources organised according to patterns extablished and fixed in Persia. The author analyzes the ritual and religious innovations carried out by the great Zoroastrian priest Kirder.
