Persian hagiography This material formed the basis for the surviving hagiographical material of Zarathustra, which is found in Middle Persian or Pahlavi texts including the "Dēnkard" and the "Wizidagiha", and in New Persian texts including the "Zaratosht-nama" and the "Shahnameh". Using and developing the historiographical methods of the "muḥaddithūn" (scholars of the sayings and history of the Prophet), Persian scholars drew on oral tradition and their own observations to write about holy figures.

In other depictions he appears with a raised hand and thoughtfully lifted finger, as if to make a point. Zoroaster is rarely depicted as looking directly at the viewer; instead, he appears to be looking slightly upwards, as if beseeching. Zoroaster is almost always depicted with a beard, this along with other factors bearing similarities to 19th-century portraits of Jesus. A common variant of the Zoroaster images derives from a Sassanid-era rock-face carving.
