The commemorative publication is dedicated to Dieter Weber, one of the most important scholars in the field of Iranian Studies, who is best known for his work on deciphering original documents in the extremely ambiguous Pahlavi cursive script, which was long considered ‘illegible’. In addition to an appreciation of his research and a bibliography of his publications, the volume contains twenty-eight contributions by renowned experts, reflecting the broad spectrum of the dedicatee’s academic interests and research work. The articles cover a wide range of topics and offer many new insights and original perspectives on religious, linguistic and historical problems, including several editions of previously unpublished texts.
