I'm currently beaming in to #ISAWNYU PhD candidate Amber Jacob's public dissertation defense in which she's giving us a peek at the heretofore unpublished, fragmentary corpus of Demotic medical texts on papyrus (originating in Tebtunis) that she's edited and translated. To date only 5 demotic medical papyri have ever been published. She says probably 8 distinct manuscripts are represented in the Tebtunis material, comprising what appears to have been a collected medical compendium with some information concerning the identity of the original ancient compiler.
Jacob's text edition will appear in due time in the Carlsberg Papyri Series as P.Tebt.Med.dem.
