This (creepy) rendition uses a bit of dramatic license to reimagine the writing of the 2nd/3rd century CE curse tablet. With that being said, it is a Primary Source, so you're hearing the exact wording from one of the Cypriot curse tablets excavated from Amathus, Cyprus!
Our reader invokes the Furies and all the underworld chthonic deities to muzzle its intended target. You'll hear some unintelligible mutterings as well. These were written to be "magical invocations" that had no discernable meaning. If you haven't had a chance to listen to my interview with Drew Wilburn, check it out!
