The volume contains forty-one papers dedicated to the distinguished Iranianist by colleagues, friends and former students, and a complete bibliography of the dedicatee. The papers deal with a variety of themes relating to Zoroastrianism, Manichaeism, Christianity, Buddhism and the multifarious religious history of pre-Islamic Iran approached mainly, but not exclusively, from a historical and philological point of view. The volume also contains a number of previously unpublished or untranslated religious texts as well as re-editions and new translations. The papers cover all Old and Middle Iranian languages, New Persian and other New Iranian languages.
