Angra Mainyu
In the "Shahnameh", the poet Ferdowsi draws on Zoroastrian scripture (with due attribution) and retains the association of "Aneran" with the Turanians. From the point of view of Ferdowsi's home in Khorasan, this identification coincides with the Avestan notion (e.g. "Vendidad" 7.2, 19.1) that the lands of Angra Mainyu (Middle Persian: Ahriman) lay to the north. The two sources do however diverge with respect to details. In the Avesta, Sogdia (Avestan "Sughdha", present-day Sughd and Samarqand Regions) is not Anērān – Sogdia is one of the sixteen lands created by Mazda, not one of the lands of Angra Mainyu.
