The main objective of the post-doctoral research project is to read and examine the Pahlavi Papyri of the Austrian National Library with a novel methodology. The project aims at a translation of the documents as well the identification of Middle Persian terms and lexical borrowings within the broader context of Trans-Eurasian cultural contacts. It involves novel methods and approaches to reading and understanding cursive Pahlavi Papyri in a more developed manner. The methodology is founded upon the application of Five Principal Criteria, facilitating a more secure reading within the historical context of the Sasanian presence in Egypt as described by Daryaee (2003 and 2009). The number of Middle Persian loanwords in Eurasian languages is such that some non-Iranian contact languages of Iranian languages, such as Armenian, were previously mistakenly classified as Iranian up to Hübschmann’s discoveries (1877). Similarly, other contact languages of Middle Iranian, such as Syriac, exhibit a considerable number of Middle Persian loans that are not included in the extant Middle Persian corpora. For instance, the Syriac term my-pwhtk, meaning ‘mulled wine, lit. wine-cooked’, is derived from Pahlavi *my-pwhtk *may-puxtag. There are examples of Middle Persian borrowings in languages such as Chinese and Hungarian (cf. Hungarian nemez ‘felt’ from Middle Persian namad), as well as Japanese and even in the Qurʿān and Arabic language, as exemplified by Jeffery (1938). Such lexical exchanges sheds light on the distinctive geopolitical position of Middle Iranian speakers and the Sasanian empire, situated at the crossroads of southern Eurasia and the Middle East. The empire served as a main corridor between the east and west of the globe, spanning from China to Egypt and from Minor Asia and the Caucasus to India and Arabia. It is noteworthy that the majority of these loanwords are also attested in Zoroastrian Middle Persian texts and appear in Pahlavi Papyri, which predominantly contain items such as botanical and faunal items, as well as products and administrative terms.
