This book studies, for the first time, the Ma?ni-yi Vahman Yasht , the New Persian version of the Zand i Wahman Yast , the most important Zoroastrian text in apocalyptic genre. Through offering a critical edition, translation, and commentary, Alimoradi argues that the MVY is not a translation of the extant Pahlavi ZWY and is derived from another recension of apocalyptic materials in Pahlavi. He also offers suggestions in identifying several unspecified characters and events referred to in the text whose identities have been debated for decades. The book is relevant to those interested in Zoroastrianism, Iranian apocalyptic traditions, and anyone studying the Arab conquests in Western and Central Asia in 6?? to 9?? c. CE.
