purely phonographic and that the remainder are logograms, as evidenced by mathematical analyses of Linear Elamite inscriptions. The archaeologist Jacob L. Dahl, who researches the decipherment of Proto-Elamite, has argued that Linear Elamite is not actually a writing system and cannot be deciphered as such, instead suggesting that it is an imitation of writing. Sign inventories An early inventory of Linear Elamite by , published in 1912, listed 64 distinct signs, noting some allographic variations. Since then, more recent discoveries have allowed more signs to be identified. In 2022, Desset and his colleagues published an updated inventory of 348 Linear Elamite glyphs, corresponding to between 80–110 graphemes, including 72 phonographic signs and their allographic variants, 4 undeciphered infrequent signs, and 33 hapax legomena. Relationship to other scripts Some scholars have suggested that Linear Elamite is derived from the older Proto-Elamite writing system. Desset and colleagues found new evidence for this; they argue that Linear Elamite is an evolution of Proto-Elamite, and that Proto-Elamite evolved, in parallel with Sumerian cuneiform, from a common substrate of simple signs and numerals used with accounting tokens and numerical tablets. He outlined some of their discoveries in public lectures, and formally published them in July 2022. As members of his research team, Desset lists the following scholars: Kambiz Tabibzadeh, Matthieu Kervran, Gian-Pietro Basello, and Gianni Marchesi.
