This article looks at the continuing fascination with the idea of monarchy in Iran, dismissed and condemned after the revolution but gradually rehabilitated through an engagement with the Shahnameh and a reinvigorated interest in ancient Iran. The interest in Sasanian Iran, as the cradle for the development of Islamic civilisation, has in turn enabled a popular re-acquaintance with Achaemenid Iran, previously frowned on for its association with Mohammad Reza Shah but legitimised by the enthusiastic endorsement of the figure of Cyrus the Great by President Ahmadinejad. This political myth of Cyrus the Great reflects the changing political dynamics of the Islamic Republic and the need to appropriate popular nationalist iconography to the state.

Although Zoroastrian Pahlavi literature preserves few geographical and ethnographic descriptions of non-Iranian historical regions, the popular book Ayādgār ī Jāmāspīg devotes several chapters to an extensive account of the landscape, social customs and religious practices of India, China, Arabia, Barbary, Ceylon (or the region of Slavs), Mazandarān and Turkestan. These descriptions share many similarities with the accounts of Muslim geographers between the ninth and twelfth centuries ce, though they also contain many Late Sasanian elements. In providing an English translation of these passages, this article aims to identify the inhabitants of these regions as well as to provide a more precise chronology of the chapters. It argues that Zoroastrian authors in the first centuries of the Islamic era, taking as a model the new Islamic science of geography, wrote or reworked these chapters with the intention of redefining and mapping the new world around them.
