The Arshama Project is not new, but since it is a valuable resource for the study of Achaemenid history, we would like to introduce it briefly.I noted the existence of the Arshama Project in passing here, but this post will take you to a link for the project itself, which involves an archive of Aramaic parchments from Elephantine.
Pasts posts on the Elephantine papyri are here and many links. Cross-file under Aramaic Watch.
