The present study will introduce and present newly discovered inked inscriptions from the Hajiabad Estakhr Cave (Marvdasht Plain) written in Middle Persian and Pahlavi script. These inscriptions are a type of Middle Persian texts that were observed using a special ink on the rock wall of the Hajiabad Cave and were not carved on the rock like the Middle Persian inscriptions. An attempt has been made to read and analyze two inscriptions from the present collection. As will be seen, it seems that these inscriptions (at least in the two cases examined in the present study) are among the monumental inscriptions written by Zoroastrian Behdeens. The content of one of these inscriptions refers to a community of a group of Zoroastrian Behdins who most likely performed a ritual act, and the other is more related to the burial a Mazdayasna folower .What has kept this type of inked writings hidden from the eyes of those who visit the places wherethey were written, is that the writings were written with a very fine pen, and the passage of time and the presence of layers of sediment and dust have caused them to not only fsced by serious damage,, but also remain hidden from the eyes of researchers .It should also be noted that this research was conducted using field and documentary methods.
