Among the Achaemenid inscriptions, DPg has been the topic of several studies since the very beginning of cuneiform studies. The photographs prepared by the DARIOSH (Digital Achaemenid Royal Inscription Open Schema Hypertext) project at L’Orientale University of Naples shed light on some ambiguities of this specific inscription and led to the proposal of a new text edition of DPg. The purpose of this article is to follow the whole history of studies on DPg until today and then propose a new reading of the inscription and a discussion of related issues, including its unique creation formula and orthography.
