Zoroastrianism is ably treated by Darmesteter in the Introduction to his translation of the “Zend Avesta.”  Instructive lectures on the religion and literature of Persia may be found in the first volume of Max Mueller’s “Chips from a German Workshop;” also in “The Religion of the Iranians,” found in Ebrard’s “Apologetics,” vol. ii.  West’s and Darmesteter’s translations of “Pahlavi Texts,” in the “Sacred Books of the East,” are also suggestive.
