I've already got an answer!
Dear Mr. ,
many thanks for your enquiry. I don't recall hearing anything about
such a discovery.
Best regards,
Holger Essler.

> I take part in an online study group on Epicureanism. Currently, we discussed the Cyrenaic philosopher Hegesias of Cyrene. In an online article (https://www.academia.edu/39345959/THE_APOKARTERON?sm=b) it is claimed, essential parts of his work "The Apokarteron" were discovered in Herculaneum in 2018. Unfortunately, we are not able to find any other reference to "The Apokarteron" in any archives available. We would like to know, to what degree the posted version of "The Apokarteron" ist fictional. Do you know something about a 2018 find?
