Bundahisn, 

Well known in the field of Iranian Studies as an essential primary source for scholars of ancient Irans history, religions, literatures, and languages, the Bundahisn is also a great work of literature in and of itself, ranking alongside the creation myths of other ancient traditions. The books
thirty-six diverse chapters, which touch on astronomy, eschatology, zoology, medicine, and more, are composed in a variety of styles, registers, and genres, from spare lists and concise commentaries to philosophical discourses and poetic eschatological visions. This new translation, the first in
English in nearly a century, highlights the aesthetic quality, literary style, and complexity and raises the profile of pre-Islamic Zoroastrian literature.
